Description

A knockout pollinator plant, Josephine horkelia is an endemic species to Jackson, Josephine and Douglas Counties in southwest Oregon and extreme northwest California in Del Norte County, where is grows on a variety of substrates, including serpentine. It is a taprooted perennial in the rose family (Rosaceae) that inhabits meadows and open woods at mainly low elevations. This species has pinnately compound, silky, hairy leaves, and the inflorescence is a cyme, with cup-shaped, white to cream colored flowers that are highly attractive to a wide variety of pollinators. When a clump of Josephine horkelia is in bloom it will be buzzing with lots of different species, from bees, flies, beetles, and butterflies. It is also a larval host plant for the two-banded checkered skipper and other butterflies that use horkelias as larval host plants. Josephine horkelia grows to about 12-20″ tall and is very drought resistant. It grows in dry locations that may be moist in the spring. Vernal moisture is fine as long as it dries out in mid summer to early fall. This variety (ssp. nemorosa) grades into Shaggy horkelia (Horkelia congesta ssp. congesta) north into the Umpqua and Willamette Valleys in Oregon, which is a rare and protected species. Josephine horkelia germinates readily and grows quickly in the garden environment, and with a little, occasional supplemental water, it will flower in its second year.

Josephine horkelia (Horkelia congesta ssp. nemorosa) seed packets contain approximately 120 seeds per packet.
