i think the caper bush is such a beauty. the leaves are solid and round, with a dark green sheen. the tutu-like flowers are white with lavender colored stamens. the buds of the caper bush are what is used in capers. the buds are picked when young and then pickled in brine to make those delicious yummy capers that we put in our pastas and salads, etc... if the buds are let to flower and fruit the fruit is the caper berry and can also be pickled, used in jams and curries.
BUT news to me was that nasturtiums have been called "poor man's capers" as you can pickle the young green seed pods to make a similar tasting tart treat! fascinating i say! nasturtiums are a wonderful plant for a garden, they grow fast and easily and the colorful flowers are edible and make a great addition to salads or garnishes on deserts. The leaves are beautiful and design-worthy in arrangements.
