Thanks for the interesting thread I've been thinking of getting this plant for a while now.
Some of the seed suppliers have said that they need a peroid of cold in a fridge to get them going. Gary- Was this your experience? I'm all for growing from seed, I can wait to see a result, but can't be doing with the faff of having to put them in the fridge before they germinate.
I want to grow them as they attract bees & butterflies.
I started mine in gritty compost in early spring (from seeds ollected the previous autumn) and did little else than watch them grow after leaving the seed trays in a shady corner of the garden. They pop up everywhere once you have them (which I like) and the bees, butterflies and moths absolutely adore them.
Once you have them you can either grow them from the seeds they produce or wait to replant their offspring (or both).
