Growing Ammobium (Winged Everlasting): A Complete Profile
By Growing Home Greens Team · August 10, 2026
Ammobium, commonly called winged everlasting for the papery white bracts and the winged ridges running down its stems, is an uncommon but easy dried-flower crop worth trying if the more familiar strawflower feels overdone.
An easy, fast-germinating start
Transplanting is recommended, sowing seed 5 to 6 weeks before your last frost with the seed covered lightly. Germination is quick, just 4 to 8 days at 65-70°F. Space plants 6 to 9 inches apart; mature plants reach 20 to 26 inches tall.
Harvest before the centers show
Cut fresh or for drying before the yellow centers show, while flowers are only half open. Unlike a fully-open flower, ammobium’s blooms continue opening as they dry, so cutting early still results in a fully developed dried flower.
Ammobium has no recorded companions or antagonists in our data. See the full companion guide for ammobium for how it’s tracked. At 4 plants per square foot, it’s a reliable, low-maintenance addition to a dried-flower row in the Garden Designer.

Varieties worth considering
- Straight-species ammobium (Ammobium alatum): Johnny's Selected Seeds sells this species plain; it's an uncommon everlasting rather than a widely bred ornamental, so there's no meaningful named-cultivar market beyond the species. (source)
