Already if you are a gardener, you want this "rare in cultivation" plant. You can hardly wait to find out what plant it is and are thinking about where you will put it, though you know nothing about it except it is "rare in cultivation".
"Rare in cultivation" is quite enough info for you to decide that if I have it and it is "rare in cultivation", you want it, too. And you are hoping it isn't too expensive or too hard to find.
Rare in cultivation!
You just have to have it. Case closed.
Yes, if you want to get a gardener to want a plant, you need only describe it as "rare in cultivation".
That's it. With those three magic words-- "rare in cultivation"-- gardeners will clamor for whatever the plant is, insist they must have it, and lie awake nights figuring out how to get it.
My red maple, Acer rubrum, is certainly not rare in cultivation. The one pictured above in my back garden is either 'October Glory' or 'Autumn Blaze'. The one in my front garden is either 'Autumn Blaze' or 'October Glory'. I have no way to tell the difference between them at this point, and I suspect even a well-trained nurseryman couldn't.
Based on the names they were given, I knew both would have good fall color. And they do.
Nice, Carol, but what is this "rare in cultivation" plant you have that I want!
Another plant with a nice fall show in my garden is Begonia grandis.
I don't think hardy begonia is "rare in cultivation" but I don't see it for sale that often and thus I don't think a lot of gardeners think to grow it in their shady areas. But if I told everyone it was "rare in cultivation", they'd be asking, begging, clamoring, for seeds and starts and divisions and cuttings--whatever they could get to get it started in their own gardens.
Again, Carol, what is this "rare in cultivation" plant you have that I want!
"Rare in cultivation" is indeed a magic phrase. You could show a gardener a picture of foxtail and describe it as "rare in cultivation", and suddenly, gardeners will want it.
This foxtail is technically "rare in cultivation" because it is a common weed and no one would cultivate it knowingly. Fortunately, it is also an annual weed so if I get out there quick and cut off those seedheads, maybe next year, I'll have less of it.
You trickster, Carol, you don't have a"rare in cultivation" plant to share, do you?
I love a "rare in cultivation" plant as much as the next gardener. I just don't have any particular one to show right now. I just know "rare in cultivation" is a sure way to get a gardener to want a plant!
