Gardeners' Notes:

I picked this up in a 4" pot one day because I loved the true-blue flowers. It looks very much like Forget-Me-Nots. It's lovely and extremely easy to grow, but one caveat: it spreads like wild fire if you let the seeds disperse. And those seeds are really something else! They stick to EVERYTHING. You'll track them in on your shoelaces if you even brush up against the plant. This summer, on a lark, I decided to gather these tenacious seeds and throw them around the whole flower bed. Well...guess what? I have the plants growing all over the place...duh! I don't find them to be deep rooted, though, and they're easy to dispose of if they get out of hand. (Mexican Primroses, for example, can be real pests, but these aren't in that category.) It's a lot easier, though, if you yank them before they set seed and hitch a ride on you like those birds that hang out on rhinoceroses.
