I do remember Buckwheat in the 'Little Rascals'. What a fun program, I don't think I missed any of them.
This is my second year with it, and it seems to be a slow grower. It isn't much bigger than when I got it. As soon as our summer dry weather arrives it get a heavy wooly coating on the leaves. There are a number of species here in Eastern Oregon, the wooly covering protects them in the high desert summer heat.
The blooms are really interesting, starting out pale yellow and morphing into red as they age.
You might like to give it a try, just give it very fast draining soil to grow in.
