Clematis glaucophylla (Whiteleaf Leather Flower) [15 Seeds]

Germination Information: I recommend these seeds only for experienced seed-starters, because germination may be very slow and irregular, requiring a good bit of patience. The easiest approach is to sow the seeds 1/4 to 1/2 inch deep in fall to midwinter, setting them outdoors in a spot protected from mice so they can germinate when they decide conditions are right. (That’s how I got my original seeds started.)

If you sow much after December, you could try giving the pot an artificial chilling period of about 3 months before moving it to a warm, bright place. It may take several alternating cycles of cold and warm temperatures for the seeds to germinate.

Please, be warned that growing these clematis is not likely to be easy. I feel confident that the seeds themselves are good: I very carefully separate the best-looking seeds from those I know aren’t viable, and I sacrifice some of the good batch as I clean them to make sure that the seed coats enclose healthy-looking centers (cutting them open to check). Some references say that it may take anywhere from one to three years for sprouting to occur. I find a fair number of clematis seedlings in my garden each year, but I have no way of knowing exactly how long it took each one to appear. Recently, I heard from a customer who sowed in early summer 2020 and just started seeing sprouts in late October 2021.

If you’re able to find a source for an already-started species plant, that is really the best way to go; otherwise, trying from seed may be your only option.
