"cobaea scandens"

"Soak the seed for 2 hours in lukewarm water before sowing. Sow at 65-75F in a good seed sowing mix. Sow the seeds on their edge and just cover with sowing mix. Keep soil damp but not wet, sealing in a plastic bag after sowing is helpful. Germination usually takes 21-30 days"

Thanks.

I just soak them in water overnight and plant them the following day. Mine usually sprout within 10 days and I've always had just about 100% germination. I cover the pots to retain moisture and keep them somewhere warm but I don't use bottom heat. My problem is that my growing season isn't long enough and if not started very early inside I don't get flowers.
