Senna marilandica (Wild Senna) [20 Seeds]


Germination Information: I recommend these seeds only for gardeners who have experience with seeds that benefit from or require a chilling period. The easiest approach is to sow the seeds (just barely covered with growing medium) in a pot in fall to late winter, setting them outdoors in a spot protected from mice so they can get a natural chilling period and germinate when conditions are right in spring.

If you sow after February, give the pot an artificial chilling period of about a month.

It is possible that these seeds could germinate (through perhaps at a less than optimal percentage) if you sow them in warm, moist, bright conditions. (Consider soaking them in warm water for a few hours before sowing.) But if you try that and no seedlings appear within 4 weeks or so, then try the artificial chilling period.

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

Wild senna (Senna marilandica, formerly Cassia marilandica) is also known as American senna and Maryland senna. It grows in shrubby clumps of upright, 4- to 6-foot-tall stems with oval leaflets and large clusters of yellow flowers in mid- to late summer, followed by long-lasting black seedpods. It’s a beauty in a large border or as an herbaceous screen. This US native is popular with bumblebees and is a host plant for several kinds of butterflies. Full sun for best flowering. Perennial; Zones 4 to 9.
