Eriogonum umbellatum
SULPHUR FLOWER, BUCKWHEAT
SKU: 2010-005
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: Sow the seeds just under the surface and water in. Leave them at room temperature (20-22 °C, 68-72 °F) for 4 weeks. If they have not germinated after 4 weeks then a cooling period is required. Cover them with plastic and place in a fridge for 4 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15C, 59F) for them to germinate. Germination can be 30-60 days after the warming period, though some can take longer.
