Tulbaghia violacea --Variegated Society Garlic--

Looks like a nice silver-streaked clumping grass, plus almost-year-round lily-like light purple blooms! Also can be eaten like a regular garlic, though unrelated. Very easy care, can be planted in very wet areas but is also highly drought tolerant. Less garlicky scent than the solid green variety. Full sun, up to 1' tall, 2' wide.
