I took advantage of Hemlady's seed giveaway last fall, and received twelve different kinds of crosses. I wintersowed three seeds of each in half-gallon translucent jugs, in December. Every jug has at least one germinated seed and most have two or three healthy looking babies. I'm delighted how easy this was. Well, so far. Heh.
I intend to pot them all up so I can keep track of who's who, at least for a while!
