Germination Information: I recommend these seeds for experienced seed-starters only, because germination may be slow and irregular.

One option is sowing in fall or winter and leaving the pot outdoors; then the seeds can sprout when conditions are right in spring. Or, you could try sowing in warm, bright conditions; if no seedlings appear in 4 to 6 weeks, then refrigerate the pot in a plastic bag for a month or so before moving it back to warm, bright conditions.

Either way, I’d suggest surface-sowing (gently press the seeds into the surface of the growing medium). Sow them into cell packs, or sow them all in one pot and transplant them (in groups) to individual pots when they’re 1 to 2 inches tall. Use groups of 6 to 10 or so if you want bigger clumps faster, or 3 or 4 per pot if you want a larger number of starter plants.

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

Description

Purpletop tridens (Triodia flava, formerly Tridens flavus), also known as greasegrass or tall redtop, is a clump-forming, warm-season grass with airy, reddish brown to deep purple panicles atop 4- to 6-foot-tall stems in mid- to late summer, and yellow fall color. It is an interesting addition to meadows, prairie-style plantings, and naturalistic gardens. (I’m not sure I’d advise it for a typical garden border because of its tendency to self-sow.) Purpletop tridens is a larval host for some butterfly species, including common wood nymph and several kinds of skippers. U.S. native (seed collected from my meadow in Bucks County, PA). Full sun. Perennial; Zones 5 to 9.

2020-harvested supply sold out. I expect to collect fresh seed in October 2021. At least 40 seeds.
