How to Choose a Plant Variety - Ep. 179

You may have an idea of what you want to grow in terms of vegetables in your garden – say zucchini and tomatoes, for example. If you open the seed catalog or website to the page for zucchini you may find as many 18 to 25 different varieties to choose from, each with their own unique set of attributes in terms of shape, size, color, growing conditions, disease resistance, pollination type, and more. Move on to tomatoes, well now you’re talking hundreds of varieties in different classes from cherry to beefsteak to sauce types. And that’s just one supplier. It can be overwhelming, and we can fall victim to the dreaded analysis paralysis – spending so much time gathering information while trying to decide that we fail to decide.

Let’s take a little bit of the overwhelm out of the equation by defining what exactly it is we are looking for in each of the types of vegetable or fruits we want to grow before we even dive into the catalogs or walk into the garden center. If you’ve got a list of attributes you’re looking for ahead of time it makes it easier to make a decision about what will do well in your garden, meet your goals, and eliminate some of the distractions. Let's dig in.


Don't forget to answer the question of the month for January: How do you plan your garden each season?

00:00:00
This is positively farming media.

00:00:04
Perusing through seed catalogs can be absolutely enjoyable, but

00:00:09
it can also be very overwhelming if you let it.

00:00:12
The same thing goes for the kiosks at the garden center or

00:00:15
plant selection. At the nursery, you may have an

00:00:18
idea of what you want to grow in terms of vegetables, say

00:00:21
zucchini, tomatoes, carrots and lettuce, for example.

00:00:24
And if you open the seed catalog or website to the page or pages,

00:00:28
plural usually for zucchini, you may find as many as 18 to 25

00:00:33
different varieties to choose from, each with their own unique

00:00:37
set of attributes in terms of shape, size, color, growing

00:00:40
conditions, disease resistance, pollination type, and all kinds

00:00:43
of other stuff. Move on to tomatoes and well,

00:00:47
now you're talking hundreds of varieties in different classes,

00:00:50
from cherry to beef, steak to sauce types.

00:00:53
And that's just one supplier. Flip through multiple catalogs

00:00:56
or websites and holy cow, it can be overwhelming and we can fall

00:01:01
victim to the dreaded analysis paralysis, Spending too much

00:01:05
time gathering information while trying to decide that?

00:01:08
We fail to decide, so let's take a little bit of the overwhelm

00:01:14
out of the equation by defining what exactly it is we are

00:01:18
looking for in each of the types of vegetables or fruits that we

00:01:22
want to grow before we even dive into the catalogs or walk into

00:01:26
the garden center. If you've got a list of

00:01:28
attributes you're looking for ahead of time, it makes it

00:01:32
easier to make a decision about what will do well in your garden

00:01:35
and meet your goals and eliminate some of the

00:01:38
distractions. Plus, you'll better be able to

00:01:41
make those impulse purchases when you go to the farmers

00:01:44
market and a grower maybe has a really cool looking variety that

00:01:48
you've never seen before. You'll know what to ask about

00:01:51
the variety and know whether it will fit your garden plan based

00:01:55
on those answers. And this goes not just for

00:01:58
fruits and vegetables, but also herbs, flowers and other

00:02:01
companions in the garden. Let's dig in.

00:02:08
Hey, I'm Karen. I started gardening in a small

00:02:10
corner of my suburban backyard and now 18 years later, I've got

00:02:13
a degree in horticulture and operate a 40 acre market farm.

00:02:17
I believe there is power in food and that everyone should know

00:02:20
how to grow at least a little bit of their own.

00:02:23
On this podcast I share evidence based techniques to help you

00:02:25
plant, grow, harvest, and store all your family's favorites.

00:02:29
Consider me your friend in the garden.

00:02:31
So grab your garden journal and a cup of coffee and get ready to

00:02:35
just grow something. So don't forget to answer the

00:02:47
question of the month for January.

00:02:48
This is a new segment for this season and I'm already getting

00:02:51
some great responses from you, so keep them coming.

00:02:54
You can use the link in the show notes to leave me a voice

00:02:56

00:03:14
The goal of these questions is to engage as a community and

00:03:18
help each other out by passing these ideas back and forth.

00:03:21
So the question of the month for January 2024 is how do you plan

00:03:27
your garden each season? You have until January 31st to

00:03:31
give me your answer and have it included in the February

00:03:34
episode. And of course, as we're talking

00:03:36
about gardening planning, that also means that I'll be opening

00:03:39
up registration for my plan like a pro garden planning course

00:03:44
here in a couple of weeks. If you'd like to be on the wait

00:03:48
list to get more information as soon as the course opens and

00:03:51
maybe get access to a couple of bonuses in the process, just

00:03:54
head to the courses page on my website and drop your info in

00:03:59
the form there. Or you can use the link that I

00:04:01
will leave in the show notes. So what are some of the

00:04:04
considerations when choosing varieties of specific things we

00:04:09
want to grow? Let's talk specifically about

00:04:11
vegetables and small fruits here, more so annuals, but this

00:04:15
could also apply to perennials too, especially when we're

00:04:17
talking about fruit varieties. To a lesser extent, these

00:04:21
guidelines would also apply to culinary herbs and florals,

00:04:26
though some of the considerations for fruits and

00:04:28
veggies may not apply to those. The first thing is to assess

00:04:32
your space. Now, I'm not really talking

00:04:34
about determining how many plants of each type will fit

00:04:39
into your garden. That's kind of a whole other

00:04:41
discussion. But just consider your overall

00:04:44
space. If you're gardening in small

00:04:47
containers, for instance, you should be looking for dwarf or

00:04:51
compact varieties. If you don't have areas for

00:04:55
trellises, then you'll be wanting things like Bush

00:04:57
varieties of tomatoes or beans, or short varieties of peas.

00:05:01
If your garden isn't located in full sun, you'll want to

00:05:05
prioritize varieties that can tolerate shade.

00:05:08
So think about the unique attributes to your overall

00:05:12
gardening space and how that might affect the growth of your

00:05:16
plants, and then look for varieties that fit those

00:05:20
attributes. Now the second consideration is

00:05:23
how many frost free days do you have to garden in?

00:05:28
What are your average daytime and night time temperatures

00:05:32
during those days? This information is going to

00:05:35
help you determine if you need to grow faster maturing

00:05:38
varieties of certain plants things maybe with a shorter

00:05:42
number of days to maturity. If you garden in an area with a

00:05:46
limited number of frost free days and daytime temperatures

00:05:50
that don't get much above maybe 80 Fahrenheit or 26.6 Celsius,

00:05:56
then you'll need very fast maturing varieties of things

00:06:00
that really like the heat, like melons or okra.

00:06:04
Conversely to that, if you live in an area that gets very little

00:06:08
frost and temperatures warm up quickly, you'll need varieties

00:06:12
of cool weather crops that mature more quickly so you can

00:06:15
avoid the heat. So think about your average

00:06:19
first and last frost dates and the average temperatures When

00:06:24
you're looking at the days to maturity or temperature specific

00:06:28
requirements for different varieties that you want to try.

00:06:31
That can help to narrow down your options.

00:06:35
The next thing to think about is what do you and your family like

00:06:39
to eat the most? Is there a specific variety or

00:06:43
varieties that fit those preferences?

00:06:46
Especially if they're more expensive than other types to

00:06:49
buy in the grocery store or at the farmers market, then you may

00:06:52
want to really put those on your list.

00:06:54
Heirloom tomatoes are a really good example of this.

00:06:57
If your family lives off tomato sandwiches in the summertime and

00:07:01
you prefer big heirloom beef steak types, you may decide to

00:07:07
grow more of those varieties than, say, the standard round

00:07:10
slicers, because the slicers are cheaper and easier to come by if

00:07:13
you need to buy them. Or do you not eat fresh tomatoes

00:07:17
a whole lot at all in the summer, but you make a lot of

00:07:19
spaghetti sauce and salsa? You might choose paste varieties

00:07:23
or Romas to grow rather than slicing, or cherry tomatoes that

00:07:27
you can pick up only whenever you need them, rather than

00:07:30
taking up space in your garden. Now, a major consideration for

00:07:35
choosing A variety is the pest and disease pressure in your

00:07:38
area. If you've gardened for a few

00:07:41
years in your current space, you likely have encountered whatever

00:07:45
routinely plagues your favorite crop in your area.

00:07:49
Are your tomatoes susceptible to early blight?

00:07:51
Do your melons get attacked by pickle worms?

00:07:54
Think about what things you've battled in your garden in

00:07:57
previous years and look for hybrid varieties of those plants

00:08:03
that have some sort of resistance bred into them.

00:08:07
Oftentimes, heirloom varieties are going to be more open to

00:08:11
attack from diseases because they haven't been selectively

00:08:14
bred to resist those diseases. So if you've had bad luck in the

00:08:18
past with an heirloom type of squash, for example, getting

00:08:23
really bad powdery mildew, then maybe look for a newer variety

00:08:27
that has resistance to that. It's no fun spending so much

00:08:30
time trying to grow something only to have it taken out by a

00:08:33
specific pest or disease when there are so many options out

00:08:37
there that can help you sort of work around that problem.

00:08:41
Now Speaking of heirloom versus hybrid, that's consideration #5.

00:08:45
Do you want to save your own seeds, or do you have some other

00:08:51
reason for wanting to grow open pollinated varieties?

00:08:55
Remember, if you want to save seeds for the next season,

00:08:58
you're gonna have to grow a variety that is not an F1

00:09:03
hybrid. An F1 hybrid is the first

00:09:06
generation of offspring from 2 distinctly different parent

00:09:10
plants. The idea is that the offspring

00:09:15
takes the best genetics from the parents and combines it into one

00:09:18
plant, making it better in some way or another than the parent

00:09:22
plants were. Now the great thing about F1

00:09:25
hybrids is that they can be more resistant to diseases in certain

00:09:28
paths, or they can be more drought tolerant or shade

00:09:30
tolerant depending on what they've been bred for.

00:09:34
They can display what we call hybrid vigor, which means a

00:09:38
stronger growth habit than either parent had on their own,

00:09:42
and they can often be more consistent in terms of shape,

00:09:45
size, flavor and production. Those can all be really great

00:09:50
benefits. The downside to this is if you

00:09:53
save the seeds from these F1 hybrids, even if they're

00:09:58
pollinated with another of the same variety or they are self

00:10:01
pollinated, the resulting offspring, which is known as the

00:10:05
F2 generation, can vary wildly from not just each other but

00:10:11
also from their F1 parents. So the variety at the F1 stage

00:10:17
is not considered to be stable. Open pollinated varieties on the

00:10:22
other hand are stable and if they are pollinated by other

00:10:26
plants of the same variety or they are self pollinated, their

00:10:30
offspring will be very similar to the original.

00:10:33
The drawback to that though is that oftentimes open pollinated

00:10:37
varieties aren't considered to be improved.

00:10:40
This means they may look and taste great, but that look and

00:10:45
flavor likely won't be uniform to each other even on the same

00:10:51
plant, and they will have fewer of those improved traits like

00:10:54
disease resistance or drought, you know, tolerance or those

00:10:58
other types of desirable traits. The most typical example I can

00:11:02
give you of this is like of heirloom tomato varieties.

00:11:05
If you take something like a Cherokee purple tomato, which

00:11:08
was one of my favorites, it's got great flavor and if you save

00:11:12
the seeds, the resulting plants, so long as it didn't cross

00:11:15
pollinate with something else, will be the same as the one you

00:11:18
saved it from. But every tomato on that plant

00:11:21
is going to be different from the next.

00:11:24
They are very prone to cat facing.

00:11:26
They are very prone to cracking and they have very little in the

00:11:30
way of disease resistance. But if you love the flavor of

00:11:34
Cherokee Purple, but you want something that's more

00:11:37
predictable in terms of growth and it's also open pollinated,

00:11:42
then you can look at the variety called carbon.

00:11:45
It's another purple type tomato. It has the same great smoky

00:11:49
flavor as the Cherokee Purple, but way more consistent in size,

00:11:54
shape, and production. So when choosing varieties to

00:11:58
grow in your garden, understanding what you want from

00:12:03
your plants can also help you narrow down the list of

00:12:06
contenders a little bit. Now, right alongside choosing

00:12:15
between open pollinated varieties and hybrids is

00:12:18
considering what grows well in your area.

00:12:23
When we talked about choosing a seed supplier last week, I

00:12:26
mentioned a local company here called Buffalo Seed Company.

00:12:29
They specialize in bio regionally adapted seeds.

00:12:33
What does that mean? They take seeds from around the

00:12:37
world and they use climate modeling to identify seeds that

00:12:42
are collected from locations that match the climate in our

00:12:45
region. And then they grow those seeds

00:12:49
in eastern Kansas and western Missouri on their farm and

00:12:52
through a network of other growers in the area.

00:12:54
And then they collect the seeds from those plants from the

00:12:58
specimens that grew the best without any supplemental

00:13:01
irrigation. This means that those seeds are

00:13:05
well suited for growing in this region, better so than seeds

00:13:08
that would be shipped in from somewhere else and just

00:13:10
immediately planted. If you can find varieties like

00:13:14
this that are bio regionally adapted or that were native to

00:13:20
your area or areas similar to yours, you may decide that these

00:13:24
should be first on your list to select.

00:13:27
This is part of the reason why the West Coast of the US,

00:13:30
specifically Northern California along the coast, can grow crops

00:13:35
that others can't. They have a climate very similar

00:13:38
to the Mediterranean. So things that are native or

00:13:42
originally came from the Mediterranean.

00:13:44
You know, things like grapes do phenomenally well there.

00:13:48
They are bio regionally adapted. So if you live somewhere that is

00:13:54
hot and dry most of the time, look for varieties that

00:13:58
originated in or were bred specifically for hot and dry

00:14:01
climates. Same thing goes for hot and

00:14:03
humid areas or cool and damp areas.

00:14:06
Look for things that are regionally adapted to where you

00:14:09
are gardening now. Consideration #7 is to repeat

00:14:14
your top performers. If you've gardened before, you

00:14:18
likely have had one or two things in your garden that just

00:14:21
did phenomenally well for you. What was the variety of that?

00:14:25
Repeat that one. Stick with that one.

00:14:28
If you're trying a new type of fruit or vegetable in the garden

00:14:30
and you don't have any kind of historical data to go on, then

00:14:34
get recommendations for varieties from local sources,

00:14:37
garden clubs, your local Master Gardeners group, your local

00:14:40
university Extension Service. For us, the University of

00:14:44
Missouri has a planting guide that not only lists the best

00:14:47
dates to plant vegetables, but also gives a list of the

00:14:51
suggested varieties that have done well in trials at the

00:14:55
university or historically with local growers.

00:14:58
So check to see if your local university has a list like that,

00:15:02
or has trials that they have done on different crops that you

00:15:06
can use as a guide for what does well in your area.

00:15:09
Use other local gardeners as a resource for suggestions in what

00:15:13
varieties have done well for them, especially when you're

00:15:16
dealing with plant disease and varying dates to maturity.

00:15:21
Tip #8. If you were in North America,

00:15:24
check out All American Selections.

00:15:27
So All American Selections, or AAS, was founded in 1932.

00:15:32
It is an independent, nonprofit organization that tests new,

00:15:37
never before sold varieties specifically for home gardeners.

00:15:41
So they do a full season of anonymous trials by volunteer

00:15:46
horticultural professionals, and the top garden performers are

00:15:51
given the AAS Winner Award for superior performance.

00:15:57
So there's three different types of awards.

00:15:59
There's four different categories of trials.

00:16:01
So there's the AAS Gold Medal award, which they only give out

00:16:05
once or twice a decade, and that is reserved for like significant

00:16:08
breeding breakthroughs. The standard award is the AAS

00:16:13
national winner. And so that's going to recognize

00:16:17
an ornamental or an edible for significant breeding

00:16:20
achievements, things that are proven to demonstrate really

00:16:24
superior garden performance as compared to others that are like

00:16:28
it on the market. So the judges are asked to

00:16:31
evaluate on things like earliness, taste, disease,

00:16:35
resistance, the uniqueness, It all depends on what species it

00:16:38
is that they're judging. And then there is also the AAS

00:16:42
regional winner. This one is given to varieties

00:16:46
that maybe didn't do well in all regions, but they did show

00:16:51
specific performance to be really, really good in just a

00:16:54
few specific regions of North America.

00:16:58
So those different awards are given in four categories.

00:17:01
Ornamentals from seed, ornamentals from vegetative

00:17:04
cuttings, edibles, which is both fruits and vegetables from seed.

00:17:08
And then they added herbaceous perennials in 2018.

00:17:13
The AAS does not actually advertise their award winners.

00:17:18
They kind of rely on like consumer magazines and

00:17:20
newspapers, garden and lifestyle blogs, Garden Club bulletins and

00:17:25
your Cooperative Extension agents to introduce the AAS

00:17:29
winners to home gardeners. But you can also go to their

00:17:34
website and download a complete list of every winner since 1932.

00:17:39
It's all in an Excel spreadsheet.

00:17:41
I will leave a link to their website in the show notes and

00:17:46
the plant breeders themselves and the plant catalogs will

00:17:50
usually mark a variety as an AAS winner because it is kind of a

00:17:54
big deal. So if you see the AAS winner

00:17:58
seal on a variety in a catalog or on a plant tag in the garden

00:18:02
center, you know that it has been, as their tagline says,

00:18:06
tested nationally and proven locally.

00:18:10
Now the 9th consideration for variety selection would be the

00:18:13
pricing and quantity available. Sometimes you can read the

00:18:18
description on a variety and it seems like a fantastic plant

00:18:21
that you would like to try, but the price point is completely

00:18:25
out of your budget. I mentioned this last week when

00:18:27
I was looking at that new bell pepper variety.

00:18:30
Or maybe it wasn't last week. It might have been at the end of

00:18:31
last season. Anyway, as much as I'd like to

00:18:34
give it a shot, I just can't justify the cost of that bell

00:18:37
pepper. This can happen with just about

00:18:40
any new variety. There is a lot of time and

00:18:43
effort that goes into plant breeding, and if something has

00:18:46
solved a particularly difficult problem, it likely took more

00:18:50
time to get to that solution, which of course means more

00:18:52
expense to recoup. The flip side of this is seeds

00:18:56
that may only come in larger quantity, possibly way more than

00:19:01
what you might need. Yes, most seeds will survive

00:19:06
beyond just one season, but not everybody is willing to hang on

00:19:09
to seeds from year to year, and some seeds really are only

00:19:11
viable for a short time. So if the variety you're

00:19:14
eyeballing only comes in a bulk package, that may be a reason to

00:19:18
either choose something else or see if you have a gardening

00:19:22
friend that might want to grow the same variety.

00:19:25
Usually though, in most cases it's the the limiting factor is

00:19:28
the price. If it's too expensive for my

00:19:30
taste, I just mark it to revisit the next season because often

00:19:34
times the price will go down after it's been out on the

00:19:38
market for a year or two. And then the final consideration

00:19:42
for deciding on a variety is who are you gardening with or for?

00:19:47
Are you going to have small children in the garden with you?

00:19:51
If so, think about growing some dwarf or miniature varieties.

00:19:55
Cherry tomatoes are enticing to little hands, miniature

00:19:58
cucumbers, Parisian carrots, brightly colored varieties of

00:20:03
anything that usually keeps their interest, at least for a

00:20:05
little while. And the more that they have a

00:20:08
hand in the garden, the more likely they are to eat the

00:20:10
things that come out of it, in my experience.

00:20:13
If you're gardening and you're bringing a box to your elderly

00:20:16
neighbors each week, maybe they have a specific variety that

00:20:21
reminds them of gardening with their parent or their

00:20:23
grandparent. Whether it's a type of vegetable

00:20:25
or it's a type of flower, choose one to grow that they'll be

00:20:29
excited to receive. And maybe you're gardening just

00:20:32
for yourself and you just want to try something new, something

00:20:35
fun or different that you've not grown before.

00:20:39
Go for it. This doesn't all have to be so

00:20:41
analytical. You should absolutely grow

00:20:44
something just for the fun of it.

00:20:46
I love growing multi colored carrots, even though they never

00:20:50
produce as much as my standard orange ones.

00:20:53
I like purple kohlrabi and yellow cauliflower because they

00:20:58
add interest in the garden and it's not just the same old, same

00:21:01
old. They don't taste any different,

00:21:03
and they don't grow as well most of the times, but they're just

00:21:06
fun. So don't be afraid to go to the

00:21:09
garden center or the farmers market and check out the

00:21:11
varieties that they have available and pick out something

00:21:14
new and different at the spur of the moment.

00:21:22
So that's 10 things to consider when choosing the plant

00:21:25
varieties that you'll put in your garden.

00:21:26
There are, of course, other things you could be considering

00:21:29
in your own personal space that are specific to you and your

00:21:32
style of gardening. But assessing your space?

00:21:35
Knowing the number of frost free days and your growing

00:21:38
conditions, What you and your family eat the most?

00:21:42
Your pest and disease pressures. Deciding between open pollinated

00:21:46
and hybrid varieties? Considering regionally adapted

00:21:50
seeds and your top performers from previous years?

00:21:53
Looking for all American selections, winners, pricing and

00:21:57
quantity, and who you are gardening for are all general

00:22:00
considerations for choosing the best varieties for your garden

00:22:04
in any given season. Check out those plant

00:22:07
descriptions and make your best educated guess and avoid the

00:22:11
analysis paralysis that comes with seed catalog overload.

00:22:15
