Cnidoscolus aconitifolius subsp. aconitifolius

Chaya, or tree spinach, is a fast-growing tropical shrub prized for its highly nutritious edible leaves, which must be cooked before eating to neutralize natural toxins. It thrives in warm, frost-free climates with moderate watering and tolerates a range of soils as long as drainage is adequate. Prune regularly to encourage a flush of tender new growth and to keep the plant bushy and productive.
