Caper

(Capparis spinosa var. inermis) This shrub with arching stems grows to three feet tall. It produces an abundance of small flower buds on first year branches from May to October that are used before they open. Each has a peppery mustard flavor and is used for sauces, meat dishes or pasta. If left unpicked these buds form large scented pinkish white flowers with long lavender colored stamens that open each morning and close in the afternoon. Hardy outside only to 18º F outside, the plant is often grown in a pot in colder climates and brought in when weather gets cold. From the Mediterranean region it likes hot weather and dry soils. Overwatering can kill the plant. USDA Zones 8-10. Self fertile.
