My pretty 2 year old clematis has seeds this year. I've cross pollinated my indigo-with whipped cream in the middle looking clematis (I ordered a red one, got this), with my mother in law's huge lavender hybrid type. The seeds are getting big, but are still green surrounded by fuzz. What next? Do I wait for them to fall off, do I store them dry, or in a fridge? Please help! I only have 2 successful babies out of 30 from last year!
