Spineless Caper is a thornless variety of the classic Mediterranean caper plant, grown for its tender flower buds rather than its fruit. Hardy in zones 8-10, this shrubby perennial reaches about three feet tall with graceful arching stems that produce an abundance of small buds from May through October. The buds are harvested before they open, brined with salt and herbs, and develop a distinctive peppery, mustard-forward flavor that enhances sauces, meat dishes, and pastas. If left unpicked, the buds transform into delicate pinkish-white flowers with striking lavender stamens that open each morning and close by afternoon, adding ornamental appeal to the edible garden.

This thornless selection removes the prickling hazard of traditional capers while delivering the same peppery, mustard-tinged brine-cured buds that Mediterranean cooks prize. The abundance of harvestable buds appears from late spring through fall on first-year growth, making it a remarkably productive edible despite its modest three-foot stature. Beyond the kitchen, the ephemeral flowers with their long lavender stamens provide genuine ornamental value, blooming daily throughout the warm months and closing each afternoon like clockwork.
The flower buds are the prized harvest, picked before they open and brined with salt and herbs to create the classic caper condiment used in Mediterranean cooking. Brined capers add sharp, peppery depth to sauces, complement meat and fish dishes, and brighten pasta preparations. The buds should be harvested at their peak readiness before flowering to ensure the tender, flavorful texture that makes capers valuable in the kitchen.

Seeds germinate in temperatures between 60-75°F. Start seeds indoors in a seed-starting mix 6-8 weeks before your last spring frost to give plants time to establish before transplanting.
Transplant seedlings outdoors after the last frost date once they have developed true leaves and the soil has warmed. Space plants at least three feet apart to allow room for their spreading habit. Harden off seedlings gradually over 7-10 days before moving them to their permanent location.
Harvest flower buds in the morning before they open, beginning in May and continuing through October. Pick buds when they are still firm and tightly closed; they should be about the size of a small pea. Once harvested, brine the buds immediately using salt and herbs to preserve them and develop their characteristic peppery flavor. If buds are left unharvested, they will open into pinkish-white flowers, which signals you've missed the optimal harvest window for that bud.
Prune lightly after flowering ends in late fall to maintain the shrub's shape and encourage bushier growth. Remove any dead or damaged wood in early spring. Light pruning of the arching stems encourages branching and increases bud production on new growth.
