Hi @MarieMartin , technically no but buying them now will be more costly. You probably won't be able to buy 'packs' of bulbs at this time of year for most alliums as they will already be in there growing season. However, you will readily find bulbs that have been started off in pots in the garden centres. They will usually have small 9cm pots available, I saw some this weekend. But you will only get a few bulbs per pot unlike the packs where you would get more. Hope that helps 😊
@richard.spicer.7906 I didn't, just planted them. They probably prefer good drainage but think they might be more forgiving compared to the larger bulb varieties. That said, I don't know if all of ours have regrown yet, I'll keep you updated! I got mine free so wasn't expecting much, but they're one of my favourites now.
