Scutellaria incana (Downy Skullcap) [15 Seeds]


Germination Information: I recommend these seeds only for gardeners who have experience with seeds that need a chilling period to germinate. The easiest approach is to surface-sow the seeds in a pot in late 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 much after December, give the seeds an artificial chilling period of about 2 months.

It is possible that these seeds could germinate if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear within 2 months or so, then try giving them an artificial chilling period as described above.

The last time I grew downy skullcap from seed, the seeds I sowed in a pot outdoors on January 1 started germinating on March 30, and those I sowed indoors (under lights, on a heat mat) on March 1 started germinating on April 12. Both sets of seedlings flowered in their first summer.

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

Downy skullcap (Scutellaria incana), also known as hoary skullcap, grows in bushy clumps typically 2 to 3 feet tall, with spike-like clusters (technically racemes) of hooded, purple-blue flowers in mid to late summer. The overall effect is something like a large catmint (Nepeta), adding beautiful color to the front to middle of a border and looking great with oxeye (Heliopsis helianthifolius) and purple and orange coneflowers (Echinacea and Rudbeckia). Deadheading may extend the bloom period, or you could let the interesting seedheads form, in which case you may find self-sown seedlings in following years. Popular with bumblebees and other pollinators, downy skullcap is native to much of the eastern half of North America. Full sun to partial shade. Perennial; Zones 4 to 9.

Collected in early September 2023. At least 15 seeds. Ecotype unknown. Shipping to US addresses only.
