Spineless Caper (Capparis spinosa var. inermis): Thornless Caper Bush for Easy Harvesting

Botanical Profile

Family: Capparaceae
Genus: Capparis (KAP-ar-iss)
Species: spinosa (spy-NO-suh)
Synonyms: Capparis inermis, Capparis rupestris, Capparis spinosa var. inermis, Capparis spinosa subsp. rupestris

Description

Spineless caper is a selection of the caper bush lacking the sharp spines found on the species. It forms a low, spreading shrub 2–3 feet tall and 3–5 feet wide with fleshy, rounded, blue-green leaves. The spectacular flowers are large (2–3 inches), white with masses of long, purple-pink stamens, opening in the morning and fading by afternoon. Blooms from late spring through summer. The flower buds (capers) and immature fruits (caper berries) are the commercial harvest.

Cultivation

Requires full sun, excellent drainage, and lean, rocky or sandy soil. Very drought tolerant. Hardy in zones 8–10; in cooler zones, grow in containers and overwinter dry and cool. The spineless form makes harvesting much easier and safer. Prune lightly after flowering.

Culinary Uses

Capers (pickled flower buds) and caper berries (pickled immature fruits) are essential Mediterranean condiments—salty, tangy, floral. Used in pasta puttanesca, piccata, tartar sauce, salads, and as garnish. The spineless variety produces the same high-quality buds.

Advantages

Eliminates the hazardous spines of the wild type. Easier to prune, harvest, and manage in gardens. Same ornamental value: beautiful flowers, attractive foliage.
