Sulphur buckwheat
Eriogonum umbellatum
Evergreen mat, pollinator favorite, perfect at the front of a park strip.
In a Salt Lake Valley yard
Sulphur buckwheat is a perennial for full sun that needs very low water once established, reaching 8–12 in tall, 2 ft wide. Expect bloom june–august, yellow aging to rust. Hardy to USDA 4–8, which covers every neighborhood from the valley floor to the bench.
Plant in fall if you can. Water weekly the first summer, then taper. On drip, one or two emitters per plant is plenty; on a park strip, set it high in gravel so the crown stays dry in winter.
Start with the strip.
