Butterfly Flag Overview
Diplarrena moraea is a rhizomatous, perennial, herbaceous species in the Iris family, Iridaceae. It is endemic to Australia and produces attractive white flowers which resemble those of Irises and tend to be produced on wiry stalks in clusters of 2-3 blooms, they are generally scented and do not last very long. Flowers have parts in multiples of three, they are white with purple and yellow colouring in the centre. Foliage is grass-like, linear to sword-shaped and measures approximately 30cm in length. It has an upright habit and is half-hardy, coping with temperatures down to -5 degrees Celsius, plant in a position of full sun, in moist, well-draining soil for optimal growth. This plant grows best in neutral to slightly acidic soil and if planting in a hot site, can cope with partially shaded light. The main difference between this plant and the other related species in Diplarrena is the size, this species doesn't typically exceed 60cm in height.
