Helleborus dumetorum (Hellebore) [10 Seeds]


Germination Information: I recommend these only for gardeners who are experienced with handling seeds that have multi-cycle germination patterns (in this case, 3 months of warmth and moisture followed by cool temperatures). The germination period takes anywhere from about 5 months to a year or more, and then it may take the plants another 3 or 4 years to reach flowering size. The entire process requires care and patience. If you are hoping to have flowers quickly, you are better off buying started plants, if you can find them.

For best results, purchase these seeds in June, July, or August. Sow them immediately upon receipt, about 1/3″ deep, and leave them outdoors so they experience a warm-moist period before the weather cools. In mild areas, the seeds may sprout in November or December; elsewhere, they should appear in spring.

If you sow from September through May, still plant the seeds immediately and leave them outdoors; they may not sprout until fall of the following year, or the spring after.

Whenever you sow, check regularly to make sure the soil does not dry out completely throughout the germination process. Also, protect from mice, which will happily feast on the seeds.

Note that this information will not appear on the seed packet you receive.

Please read the description as well before ordering.

Helleborus dumetorum isn’t one of the showiest hellebores, but it’s worth growing if you appreciate subtle beauty. This uncommon species is also an excellent addition to a collection if you enjoy exploring the variety of traits this genus has to offer.

I raised my plants from seed I purchased from Will McLewin many years ago. As shown in one of the photos here, they tend to emerge with near-black leaves (which soon turn green), but I don’t know if this trait will carry through the seeds. The slow-growing plants reach about 8 inches tall and bloom in late winter to mid-spring, with small (1-inch) green flowers. Unlike most hellebores, H. dumetorum is deciduous. It is also more decidedly a shade-lover, so keep that in mind when siting it. It is reportedly hardy in USDA Hardiness Zones 4 to 8.

Also, please know that I do grow other hellebore species and hybrids. H. dumetorum starts flowering earlier than my others, and its seedlings seem to come true here. I don’t know how likely it is to cross with others, but I just want to be honest that there is a possibility.

Collected in late May and early June 2022. Each packet contains at least 10 seeds. Very limited quantity; 1 packet per person.

Please read the Germination Information section of this listing before placing an order for these seeds.
