ssp. formosum & giganteum (er-ee-OG-uh-num jy-GAN-tee-um)
Family: Polygonaceae (Buckwheat Family)
Native to: San Clemente (var. formosum) and Catalina (var. giganteum) Islands; Dry slopes and
ridges, rocky cliffs in chaparral, coastal sage scrub.
Growth characteristics: perennial shrub mature height: 3-8 ft. mature width: 4-6+ ft.
Large rounded shrub with spreading branches and silvery-green foliage. Semi-deciduous.
Attractive gray-green foliage.
Blooms/fruits: Blooms May-Aug. Tiny pink-cream flowers in dense flat heads held above the
foliage. Flowering heads look like baroque lace (hence the name ‘St. Catherine’s Lace’. Showy.
Flowers turn to bronze-red as they age.
Uses in the garden: Tall informal hedge, on dry sunny slopes, erosion control, specimen plant. Dried
flowers can be used in arrangements. Nice against walls or in the back of beds. In large pots, it can
be pruned up to show its thick, rough trunk and branching structure. Showy and big, it requires
adequate space to showcase its character.

Hairstreak butterflies. Also good bird and small animal habitat: provides cover and seeds for food.
Requirements:
Element Requirement
Sun Full to partial sun
Soil Best in rocky, well-drained soils; any local pH
Water Little to no summer water (will be somewhat drought deciduous)
Fertilizer None needed
Other
Management: Easy to grow. Cut back after blooming. Hybridizes with other native buckwheats, so
don’t plant near native buckwheat stands.
Propagation: from seed: yes, use fresh seed by cuttings: hard/semi-softwood in late summer/
fall
