Corydalis flavula (Yellow Fumewort) [15 Seeds]

(1 customer review)


Germination Information: It’s pretty easy to get yellow fumewort established if you sow fresh seed soon after it ripens (in mid-May through July). Start in a pot or a nursery bed, just covering the seeds, and look for seedlings to start emerging in late summer or early fall. I have had good luck transplanting the seedlings in September and October to the spots where I want them to flower in spring.

Yellow fumewort (Corydalis flavula) is a dainty little species with deeply cut, blue-green to light green foliage and clusters of small, yellow flowers in early to mid spring, followed by reddish seedpods that are hidden under the leaves. The clump reaches 6 to 10 inches tall and wide in full bloom. After flowering, it declines quickly and is usually gone by early to mid June, but it will drop seeds before that. Self-sown seedlings usually appear in late summer to early fall, then overwinter as small plants.

Yellow fumewort grows happily in deciduous shade (sun in early to mid spring, then shade) with average to moist (but not soggy) soil. This species is native to many parts of the eastern half of the United States but isn’t especially abundant anywhere. I collected these seeds from plants I grew from seed of a Pennsylvania Piedmont ecotype. Annual (technically a winter annual).

Collected in mid- to late May 2023. At least 15 seeds per packet. PA ecotype. Shipping to US addresses only.

    I’m purchasing Corydalis flavula for a second time from Nan. This is a rare native plant in my area and difficult to find seed sources. The first round of seeds are doing well in my growing zone (9A). The early pollinators will appreciate the blooms this spring. The seeds were well packaged, delivered quickly and the customer service is at another level. Nan will do everything in her power to get you the best possible seeds in a timely manner.
