The first snowdrops are out, and there's no more hard frost forecast. I've planted sixty Aquadulce Claudia, in pots. I's a pretty indestructible variety, though I've given up trying to overwinter it due to waterlogging, which does kill it. If the worst comes to the worst, I have more. Come April, I've got Red Epicure and Crimson-Flowered Broad Bean to go in, but they're not so hardy, and I don't want them flowering at the same time. I can cope with two varieties at opposite ends of the plot, as they're unlikely to cross-pollinate, but I'm not sure about three.
Someone in the States has sent me eleven named varieties of couve tronchuda. It's a rare old Portugese cabbage, which is apparently loose-leaved, somewhere between a modern cabbage and a kale. A couple of places used to stock generic seed, but it's now disappeared, So I asked around, and that's what I ended up with. I've now got more rare brassicas than I know what to do with; the seed is in the freezer as it'll take several years to grow it all out. I can probably manage two varieties a year if I net them on alternate days while they're flowering so they don't cross. The hedges round my plot do a lot to isolate it from the rest. I'm scrounging unusable net curtains from the church charity shop, which gets inundated with stuff that's fit for nothing but the rag man.
