Evelyn, I got a whole variety of them - 25 species.
Multiple species of Antennaria, Dianthus, Globularia & Iberis - mainly because I've been successful with others of these species in the past.
But I also have branched out with a bunch of others which I either haven't tried or wasn't successful with in the past. This whole seed-sowing thing is new for me, so I'm just diving in and crossing my fingers.
