The story
Capers grow out of cliffs and old walls across the Mediterranean and Middle East, and the pickled buds have seasoned dishes since Sumer; the Bible mentions them, and Pantelleria and Salina still pick them by hand at dawn. The plant wants rock, sun and no water.
Planting
Full sun, rocky, sharply drained, even alkaline soil; plant a rooted cutting in a wall crevice or raised bed in spring. It dies in wet clay.
Growing
Water almost never once established; never feed. Cut back hard in late winter; it fruits on new shoots.
Harvest and use
Pick flower buds every two days in summer, before they open; cure in salt or brine for a month. The fruit, caperberries, can be pickled too.
What to watch for
Wet soil and cold; caper moth in the Mediterranean.

The Caper Asks for Nothing and Gets Everything
The caper grows out of a cliff wall with no soil, no water and no apology, and I find this deeply moving. Sumer was already pickling the buds, so we are merely the latest guests at an ancient lunch. The guide says to pick the flower buds every two days in summer, before they open. Every two days! A plant that demands a standing appointment while asking for nothing else. Socrates would have pondered it. I ponder it over a second plate. Give it a rocky crevice, never wet clay, and leave it alone. Neglect is the whole technique.
