Warriner Lytle Buckwheat, Eriogonum fasciculatum 'Warriner Lytle', is a low horticultural selection of the perennial soft woody shrub species Eriogonum fasciculatum (California Buckwheat). This tough and drought tolerant native cultivar combines the hardiness and habitat value of the species, with the garden versatility of its selected low-growing form. This dependable groundcover plant is adaptable and easy to grow.

Warriner Lytle Buckwheat can reach 1-2' high but is often more prostrate. Its arching branches can spread 4'-5' wide. Fine dark-green, needle-like green leaves are topped in the summer by globe shaped clusters of pinkish-white to cream flowers, that then age to a rusty red-brown in late summer or autumn. It adds floral color to the summer native garden, and is a major draw in butterfly, pollinator, and bird habitat gardens. This low buckwheat makes a good ground cover, or an accent plant beside patios and pathways for enjoying the blooms and many butterflies they attract. With its dense foliage coverage and deep roots this ground cover is good for erosion control, slope stabilization, suppressing weed germination, and dry hot slopes.

California Buckwheats are a favorite nectar source for many butterfly species, native leaf cutter bees, and honey bees. As the summer progresses into autumn the birds will flock to feed on the seeds. Warriner Lytle Buckwheat will tolerate almost any soil type, including clay when planted on slopes or raised mounds, and take summer's high heat. Once established it needs very little water, one can provide occasional deep watering or none. Eriogonum fasciculatum 'Warriner Lytle' was selected and introduced for gardens by the Theodore Payne Foundation in Los Angeles, who named it for one of their dedicated volunteers.
