Letting a few clematis plants grow is the closest that I’ve come to playing the lottery. It looks like I’ve won, judging from the first flower that opened last week.
Let me explain. I have a half-dozen or so clematis plants of named varieties that I got from nurseries. A few years ago, I started noticing small plants – seedlings of the named varieties, especially from near a Nelly Moser plant – sprouting near the mother plants. I meant to save a couple; I even transplanted some. But these first seedlings succumbed to neglect. More recently, I’ve paid closer attention to the seedlings, especially those that sprouted fortuitously near the fence around the vegetable garden.
The gamble was that some seedlings would be gardenworthy. (Not that big a gamble: If not gardenworthy, I could just dig them out and walk them to the compost pile.) Named varieties of clematis, such as my plant named Nelly Moser, are propagated by cloning – that is, every Nelly Moser plant is genetically identical to every other Nelly Moser plant. Clones of any plant are propagated by root, leaf or stem cuttings, by grafting or by some other method of asexual propagation.
My seedlings arose from seeds that dropped from a pollinated flower – that is, the seedlings are the result of the sexual union of pollen and egg cells. Whatever jumbling around of genes happened during that union will be reflected in the plants’ growth and flowers.
My first seedling flower spread open clear blue petals: beautiful. It’s a keeper. If I deem it truly and uniquely spectacular, I could give it a name and multiply it asexually to spread the joy. Then it would become a named variety – or, to use the more professionally acceptable term, “cultivar,” from the words “cultivated variety.” The word “cultivar” grates on my ears; I refuse to use it.
That unspeakable “c-word” came about because the word “variety” was too general; it could mean two different things, plantwise. One meaning is a garden variety, as in Nelly Moser clematis. The other kind of “variety” is a botanical variety.
In the classification of plants, a botanical variety is a subclassification sometimes occurring within a species. That occurs if there are populations within the same species that are sufficiently similar to distinguish themselves from other populations within a species, and the differences are inheritable. (Both populations are, of course, sufficiently similar to be included within the same species.)
Botanists have not chosen to bastardize the English language with so ugly a word as “botanivar” to mean a “botanical variety.” Likewise, there’s no reason for horticulturalists to bastardize our language with the word “cultivar.” I’ll stick with “cultivated variety” or, if the sense is obvious, just “variety.”
The flowering habit of my clematis seedlings is also of interest – that is, when does it flower? Some clematis flower only on new growth, which means that they flower later in the season. Some clematis flower only on old growth, which means that they flower early in the season. And still other clematis flower on both new and old growth, which means that they flower early and late, over a long season.
As I detail in my book The Pruning Book, pruning technique varies depending on a clematis plant’s flowering habit. Early bloomers are best pruned right after they finish blooming. Late bloomers are pruned before growth begins for the season. And you do a little of both for plants that bloom early and late. (My book groups cultivars – whoops! I mean varieties – of clematis according to their flowering habits and pruning needs.)
My seedlings have mostly appeared near the “feet” of Nelly Moser, which flowers early in the season, so presumably will be similarly inclined. That is the case with the seedling that recently unfolded its blossoms. But it could flower again this season.
For now, I’m enjoying the flowers of the first bloomer and looking forward to what unfolds on the stems of other seedlings.
“How to Grow a Lot of Vegetables with Little Space, Time and Effort” is the topic for an upcoming workshop that I’ll be holding here at my farmden in New Paltz on June 23 from 9 to 11:30 a.m. (The growing season is still young: It’s not too late to get more out of your garden; it’s not even too late to start a garden!) The cost is $50 and space is limited, so registration is necessary. For questions or registration, contact me at (845) 255-0417 or [email protected]
