SULPHUR FLOWER, BUCKWHEAT
Eriogonum umbellatum
SKU: 2010-005
Description
Eriogonum umbellatum is a species of wild buckwheat known by the common name sulphurflower buckwheat, or simply sulphur flower. It is native to western North America from California to Colorado to central Canada, where it is abundant and found in many habitats, including the sagebrush steppe and alpine areas. It is an extremely variable plant and hard to identify because individuals can look very different from one another.
It is a popular larval host, feeding the bramble hairstreak, desert green hairstreak, lupine blue, Mormon metalmark, Rocky Mountain dotted blue, Sheridan's hairstreak, Sonoran metalmark, and western green hairstreak.
The wildflower gardening author Claude A. Barr complemented sulphurflower buckwheat as a "treasure in appearance and in adaptation in my garden." It is valued for its very low water usage for xeriscaping.
These seeds are very rare and are in limited supply.
Type: Hardy perennial
Hardiness zones: 4-9
Height: 25cm, 10"
Seeds per pack: 5
Germination: Start these seeds right away to preserve viability, no matter the time of year. These seeds require a period of cold. Sow the seeds just under the surface of a sterile seed-start mix, and water in. Leave them at room temperature for 2 weeks. They will not grow yet. Then cover them with plastic and place in a fridge for 5-6 weeks. Be sure they stay moist. After the cold stratification period they are then brought back to room temperature for them to germinate. If possible, the best location for sowing in March, April and May, is in cold frame or a cold greenhouse where they will receive the cold period and fluctuating temperatures naturally.
