California Buckwheat

Eriogonum fasciculatum

California Buckwheat is one of the most important native plants for pollinators in southern and coastal California. This semi-evergreen shrub typically grows 2–4 feet tall and wide with fine-textured, needle-like foliage and a rounded, mounding form that brings structure to dry landscapes.

From late spring through fall, the plant produces tight clusters of small white to pink flowers that gradually darken to reddish-brown seed heads, adding extended seasonal interest. These flowers are a magnet for many pollinators and beneficial insects and are considered one of the top nectar sources for Southern California butterflies.

Its deep roots make it highly drought-tolerant once established, perfect for erosion control on slopes or in fire-wise plantings. California Buckwheat thrives in full sun and well-draining soils and fits beautifully into dry gardens, habitat restorations, and native hedgerows.

Maintenance Tips

  • Prune lightly in late fall or early winter to remove old seed heads and maintain shape.
  • Avoid overwatering - excess moisture can lead to rot.
  • Allow flowers to go to seed to provide food for birds and additional structure.
