Seacliff Wild Buckwheat
Eriogonum parvifolium
Eriogonum parvifolium, commonly known as Seacliff Buckwheat, is a low-growing, perennial shrub native to coastal California. It features small, leathery, gray-green leaves and produces clusters of tiny, white to pink flowers that bloom from late spring through summer. It is drought-tolerant and attracts pollinators, making it a valuable plant for coastal gardens and restoration projects.

Salvia clevelandii
Cleveland Sage
Salvia clevelandii
Cleveland Sage and Seacliff Buckwheat share similar water and sun requirements. Their contrasting foliage and bloom times create visual interest, and both plants attract pollinators.
Achillea millefolium
common yarrow
Achillea millefolium
Yarrow provides a different flower structure and color palette, complementing the buckwheat. It is also drought tolerant and can thrive in similar conditions.
Baccharis pilularis
coyote brush
Baccharis pilularis

Coyote Brush can quickly outcompete Seacliff Buckwheat due to its more aggressive growth habit and larger size, especially in less managed garden settings.

Aphids

Aphids are small, soft-bodied insects that suck plant sap, causing yellowing leaves, stunted growth, and the production of sticky honeydew. They can infest the stems, leaves, and flower buds. Infestations can also lead to sooty mold development.

Scale Insects

Scale insects are small, sap-sucking pests that appear as bumps on stems and leaves. They weaken the plant, cause yellowing, and can lead to plant decline.

Steps:

    • Collect seeds from mature plants in late summer or fall.
    • Sow seeds in well-draining soil, either directly in the garden or in containers.
    • For cuttings, take semi-hardwood cuttings in late summer.
    • Root cuttings in a well-draining potting mix, keeping the soil consistently moist.
    • Transplant seedlings or rooted cuttings to their permanent location after the last frost.
