I'd sow them now follow natures pattern.

I collected seeds from my Aquilegia plants, few weeks back and sowed them, have some coming up in trays.

Agreed, the seeds germinate far better fresh. If you do save some, then when dry, store in the Salad compartment of the fridge.

Thank you Moon grower, Dian and Owdboggy . . . the garden soil is currently dry and hard, so I'll sow them in trays. Would the cool of the cold frame be the best place for them . . . or the very warm greenhouse?!

Many thanks for your advice :)

Cold frame Sheila

Thanks Moon grower . . . they'll be fine until they germinate. (Had to move other seedlings as we seem to have a peckish (pesky?) mouse, but I don't want him killed.)
