Giant Wildrye

Leymus condensatus

Giant Wildrye (Leymus condensatus) is a landscape plant valued for its form and structure as much as its bloom. It reaches roughly 8.5 ft at maturity and blooms in mid spring. Match it to full sun to part shade and keep the root zone consistently moist. One caveat: like any plant, its published range is a guideline, not a guarantee, for the specific microclimate of your yard. Given a spot that matches its light and water needs, it is a dependable, low-drama addition to the yard.
