Chasmanthium latifolium (Northern Sea Oats) [25 Seeds]

$4.25

Germination Information: The easiest approach is to surface-sow (do not cover) the seeds in fall to midwinter, 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 before moving it to a warm, bright place for germination.

Transplant the seedling (in groups) to individual pots when they’re 1 to 2 inches tall. Use groups of 6 to 8 or so if you want bigger clumps faster, or 3 to 5 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

Northern sea oats (Chasmanthium latifolium, formerly Uniola latifolia) is a 3- to 4-foot-tall, perennial grass with flattened flower- and seedheads in summer and fall. The dangling heads look terrific in fresh or dried arrangements, adding a playful touch as they nod and sway with the slightest movement.

Be warned, though: While the plants of this US native grass are clump-forming, they will self-sow freely in the garden. For that reason, you might want to consider keeping northern sea oats in a meadow planting or “wild garden,” where it can seed around without being a problem, or in a tough site where daintier plants don’t thrive (in a roadside planting, for instance). Or, commit to cutting off the seedheads in mid- to late fall. Full sun to partial shade. Perennial; Zones 4 to 9.

Harvested in mid October 2022. At least 25 seeds. Ecotype unknown.
