The leaves of this nasturtium are mottled white and green, while the flowers are deeply hued pastels. The combination is a striking one, and you may be tempted simply to stand back and behold the plant's beauty. But do get closer--nasturtium is edible! Its leaves and blooms have a nice peppery flavor; they enliven any salad. The immature seeds, when pickled, make a terrific substitute for capers. Nasturtiums can play a starring role in any edible landscape.
