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.

I grow several species of leather flower- (or leatherflower-) type clematis in my garden and adore them all. I normally sell their seeds in a mix, but I’ve finally decided to offer this species by itself as well. Whiteleaf leather flower (Clematis glaucophylla) flowers later than the other species here, usually starting  in early July and continuing into October, so there’s little chance of it crossing with the other species. (It may begin as early as late spring in the South.) I find self-sown seedlings of it every year, indicating good viability, and so far, all of the seedlings have been true to type. Like the other leather flower clematis, this one flowers on the current season’s growth; here, it dies all the way to the ground every year. The vines reach 10 to 12 feet long: just right for climbing up one side of an arbor, over the top, and cascading down the other side a bit. Rich pink on the outside and creamy yellow on the inside, the thick-petaled blooms turn into showy clusters of golden and then brown, fluffy-tailed seeds, enhancing its ornamental value. Hummingbirds love the flowers too! Full sun to partial shade. The species is native to the southeastern US; as far as I know, it is hardy in Zones 6 to 9.

Collected in late October and early November 2022. At least 15 seeds. Unknown ecotype.
