Lemongrass, Cymbopogon citrates, is valued in the garden for its fresh lemony fragrance, carefree ornamental appearance and toughness. Unlike many ornamental grasses, it has no sharp edges to cut skin, so is safe to grow near walkways or where children play. Fleshy basal stalks are an essential flavoring ingredient in many Thai and Vietnamese recipes. Use the leaves for teas, cooking, and potpourri. Lemongrass is easy to grow, and adapts well to partial shade and moist conditions. Plants are fast growing and can get quite large – up to 3 feet tall and wide – but are not invasive.

Thai Chili Pepper, Capsicum frutescens, is a very hot pepper variety (50,000 to 100,000 on the Scoville pungency scale). It is known as prik ki nu in Thailand, its home of origin. Plants grow to about 12 inches, and become covered with 1 ½ inch to 3 inch long peppers that are green at first but ripen to red. Both colors appear on the plant at the same time, making this variety ornamental as well as edible. Peppers are thin fleshed. Use fresh or dried.

Leaves have a unique, mild flavor and can be used as a wrap for steamed fish, as an addition to stir fried dishes or prepared as tempura.  Shiso is also often seen as a garnish on sushi platters. This attractive warm weather annual grows to 3 feet tall. Large serrated heart shaped leaves are a bronzy red. Plant in full sun or afternoon shade. Pinch back frequently to keep plants bushy and to prevent flowering.
