Citrus reticulata – Mandarin OrangeCitrus reticulata, the mandarin orange, is an evergreen citrus with rounded orange fruit, neat branching and sweetly scented white blossom. In a container it forms a small tree with aromatic leaves and seasonal mandarin fruit colour. Give it very bright light, warmth during active growth, a free draining citrus mix and deep watering with slight drying between waterings; protect it once nights fall below about 10C.
