Hi, I bought some autumn clematis about 3 months ago. I tried putting 4 seeds in soil and a month passed and not 1 seedling, I dug them up and there they were the same seeds that I put in, it hadn't even sprouted. Also, I've tried to germinate them in a ziploc and nothing, also in a jar with wet cotton and nothing. The last one I've tried is that I put 3 seeds in a jar with wet cotton then I read to put them in te fridge then after 2-3 weeks to take them out of the fridge. I took them out yesterday but I doubt it's gonna work since nothing has worked. What other things can I do that has worked for you guys?

You are not waiting long enough - Sweet Autumn Clematis takes less time to germinate than most other clematis seeds - this is what I found on one of the websites when I googled SAC seed germination: Germination: Slightly difficult. Sow seed in late winter. Sow seed on good seed starting mix, covering seed very lightly leaving portions of seed exposed as light will aid germination. Place container inside sandwich baggie to retain moisture and place container in refrigerator for 3-4 weeks. Remove container and place in cool 60-65°F location. Seed should begin germinating in 10-30 days. Alternatively, sow seeds in late autumn/early winter in large container on good seed starting mix, covering lightly with mix. Place container in sheltered location, preferably on the north side of a house or building where it won't be exposed to direct heat of the sun. Bring container indoors in spring for germination, or leave outdoors and begin checking for germination as the weather warms.


Check out Brian Collingwood's website. He has been growing and hybridizing clematis seed for years. http://bcollingwood.com/index1.htm
