I have three echinacea seedlings. Out of six or eight planted. I'm babying these on the kitchen windowsill because have had such difficulty getting any to transplant size, in the past. The other tray I sowed never germinated- I think that was from my self-saved seed. When I opened the packets noticed the bought seed was nice and plump, my gathered seed was flat. I'm guessing the seed I saved myself just wasn't viable.
