New And Nutritious Crops For St. Croix By Jay Reynolds Blue Chip Farms, Frederiksted The tropics contain more different types of plants than most of the world. In our island of St. Croix, however, we use only a fraction of the great variety of plants which grow here. The purpose of this article is to mention several vege- table plants which grow on the island successfully and to share with you my experiences with them. Two green vegetables are available which are vigorous, fast growing, and nutritious. Two root crops are also men- tioned which are productive and space saving. All of these can be grown in a home garden and one is suitable for con- tainer or hydroponic growing. Amaranth The green vegetable amaranth (Amaranthus dubious, A. gangeticus, A. hybridus) is an extremely ancient plant once cultivated by the Aztecs as a grain. The amaranth I am writing of here is known as vegetable amaranth, "spinach", Kallaloo, or Bajee. It already is collected here in St. Croix from wild plants and is a common ingredient in local kalla- loo stews. The reason for mentioning it here is because, while most wild amaranth only grows short (1-3 foot) plants with small leaves, other varieties which grow to 6 feet tall and with 8-10 inch leaves are now available by seed and in several forms growth and color. Amaranth has another distinctive feature, it grows fast! A plant only 6 inches high, when well supplied with water, can grow up to 12 inches in one week, and after cutting it back, be ready for harvest in two weeks. The long stems and leaves of the young plant and the top 8-12 inches of older plants are harvested and the taste is vaguely like spinach, but no chalky aftertaste. The interior of large amaranth stems provides a crisp treat similar to broccoli stems. One drawback, however, in growing amaranth is pest control. All amaranths, wild and planted, will require con- trol of caterpillars (worms) weekly or else they will destroy the crop. They can be easily protected, however, by a safe, organic spray of Bacillus thurigiensis (Bactospiene) which can be used up to the day of harvest and is harmless to man, animals, and other insects. This productive, fast growing green is a natural for this island, it's always been here wild and new varieties make it better. Water Spinach Water spinach (Ipomoea aquatica) is an edible green which is a member of the same family as sweet potatoes. This plant prefers a life in a swampy environment, but some varieties can also be grown in soil with adequate moisture. It grows as a sprawling vine if left uncut but if cut produces a clump of shoots which grow back after cutting. It can be easily propagated by seeds or cuttings planted 6 inches apart. Due to its ability to grow in wet swampy places many schemes of cultivation are possible. In Malaysia, it is grown in fish ponds, the spinach is fed to pigs, the pig manure is used to fertilize the ponds, and thus three products, fish, spinach, and pigs can be harvested at the same time. A friend of mine grows it on a portion of concrete pation in 1- 2 inches of dirt which is frequently flooded with water from a leaking roof gutter. I believe it could be grown in any container holding water or hydroponically at home with ease. Water spinach grows in moist rich soil or water. The leaves can be used for salad or kallaloo and has a mild pleasant flavor. The young shoots of the plant 6-12 inches long are cut back, the leaves and hollow stems are chopped for use in salads, stir fries, soups, and stews. They have a mild olive spinach flavor but also no aftertaste. The fresh leaves have a protein content of 2-4.5%. Amaranth and water spinach contain low levels of oxalic acid, unlike other spinach which can block calcium absorption in the body. Jicama The jicama is native to South America and is grown com- mercially in Mexico. It is a unique plant which grows like a vegetable but produces a turnip shaped root which tastes like an apple! The plants are grown from seed spaced one foot apart and mature roots are up to 6 Ibs. in 120 days. In St. Croix, my jicima have grown to 2 Ibs. and are excellent used raw in salad or in stir fry dishes. Jicama is a member of the
