Eupatorium hyssopifolium (Hyssop-Leaf Thoroughwort ) [15 Seeds]


Germination Information: I recommend these seeds only for gardeners who have experience with seeds that need a chilling period.

The easiest approach is to surface-sow the seeds in a pot in fall to early winter, setting them outdoors in a spot protected from mice so they can get a natural chilling period and then germinate when conditions are right in spring.

If you sow after January, give the pot-sown seeds an artificial chilling period of about 2 months before moving them to a bright place for germination.

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

Hyssop-leaf thoroughwort (Eupatorium hyssopifolium) produces upright stems somewhat sparsely clad in short, narrow, grayish green leaves. In late summer through early fall, the 2- to 3-foot-tall stems are tipped with flattened clusters of many tiny, white flowers. The blooms are favored by a variety of pollinators and beneficial insects. Hyssop-leaved thoroughwort spreads moderately by underground rhizomes and looks right at home in a meadow (where mine grows naturally, on a dryish slope) or in a naturalistic border with grasses and other late-flowering perennials. Full sun to light shade. Perennial; Zones 4 to 8.

2022-collected seeds are sold out. I hope to collect again in mid to late October 2023. At least 15 seeds. PA ecotype. Shipping to US addresses only.
