Rudbeckia fulgida var. deamii (Deam’s Orange Coneflower) [20 Seeds]
Germination Information: I recommend these seeds for experienced seed-starters only, because they may require some patience. The easiest approach is to surface-sow (do not cover) the seeds in fall to mid-winter, setting them outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.
If you sow after February, give the pot 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 3 weeks or so, then try the artificial-chilling approach mentioned above before moving them back to warmth and light.
Note that this information will not appear on the seed packet you receive.

If you’re looking for something a bit different from the widely planted Rudbeckia fulgida var. sullivantii ‘Goldsturm’, consider giving this variety a try. Its flowers are about the same size, but Rudbeckia fulgida var. deamii starts flowering several weeks later than ‘Goldsturm’, providing a splash of welcome color in late summer and early fall (late July to early September in my southeastern Pennsylvania garden). The branching stems usually reach 2 to 3 feet tall, with an abundance of dark-centered golden blooms that attract butterflies, and the long-lasting seedheads supply a wealth of seeds for birds as well as plenty of self-sown seedlings. This variety of orange coneflower is native to parts of the central US. Full sun to light shade. Perennial; Zones 4 to 9.
Collected in late September 2022. At least 20 seeds. Unknown ecotype.
