Sulphur Flower Buckwheat Eriogonum umbellatum

Sulphur flower is a buckwheat family perennial native to parts of the western US, where it can be found in dry rocky soils in forests, foothills slopes and mountain ridges. Needing little moisture to perform well, they are suitable for water-wise gardens.  Allowing the soil to remain wet can be fatal to this plant.  

Individual plants can look different from one another, making it difficult to identify.

It is highly variable in shape and color. The red tinged buds open to reveal yellow flowers that bloom from the summer into fall, giving color to its location for an extended period of time.  Flowering occurs at the top of the stems forming dense clusters up to 4" wide.  As the blooms dry, they become a rusty color, making them a great addition to dried arrangements.  

Its matting habit, spreading to up to 3' wide, make this plant a great ground cover in locations that include hot and dry conditions.  During the cooler months, the foliage will turn to shades of red/burgundy, which will extend the season for this semi-evergreen plant.  

Propagation is best by planting seed.  This plant is difficult to divide due to its long taproots.  The roots also make transplanting a challenge.  

Insects, Diseases, and Other Plant Problems:  No serious issues.  Powdery mildew and rust are occasional problems.
