Conservatory Greenhouse Shrubs

A tender, fast-growing shrub. Large green leaves are covered in fine hairs, with purple colouring along the veins. Spines protrude from the upper leaf surface and stems. Leaves and stems may display more purple colouring when young. Suitable for use in tropical style, ornamental planting. If given a long growing season it will produce white flowers, followed by orange fruits. Juice is made from the fruits when grown in tropical regions, but the fruits are covered in tiny hairs and may not fully ripen in the UK, so caution is advised
