Thriving in warm, wet conditions Okinawa Spinach does best in subtropical and tropical areas; it is sensitive to frost. An attractive plant with shiny leaves that are green on top and purple underneath; the flowers are very small and orange. It grows best in full sun to partial shade. It needs ample water, rich, fertile well-drained soil that is kept mulched and prefers a pH of between 6.1 and 6.5.
USES
Food: It is a very nutritious vegetable, eaten raw or cooked. The leaves and young shoot tips are steamed, used in stir fry, tempura, stews, and soups. Try not to overcook it as it can become slimy. The leaves have a crisp, nutty taste with a faint hint of pine. In Okinawa the leaves are often fried and served as tempura. It can also be steamed with rice if it is added for the last 7 minutes of cooking time. This leafy green is also known as cholesterol spinach, and there are many claims that it lowers cholesterol. Young leaves have a much better flavour than the older leaves.
Edible Landscaping: The vivid leaf colour makes this a good choice as a background plant in ornamental beds. Okinawa Spinach can be used in landscaping as a groundcover in full sun (with enough water) or it does well in partial shade. It is very adaptable to container gardening and hanging baskets and will grow inside on a windowsill with good light.
