2017 Gardening: Septic Planting

Amaranthus gangeticus is considered a synonym of A. tricolor,[6] but has been recognized as a separate species in the past. A. gangeticus is also known as elephant-head amaranth. It is an annual flowering plant with deep purple flowers. It can grow from 2–3 feet in height. In Bangladesh, it has been used as a leafy vegetable. It may inhibit calcium retention in rice-based diets.[7]

This bizarre and slightly goofy annual flower bears congested sprays of deep purple flowers which resemble pointing fingers! Although it is native to South America, in India and Africa the leaves and stems have been eaten as a salad vegetable. It is usually steamed as a side dish in both China and Japan. Scientific study suggests that it may inhibit calcium retention, and in addition it has a high content of carotene, ascorbic acid, and folate and may prove an efficient antioxidant. http://www.plant-world-seeds.com/store/view_seed_item/4670
