One of our favourite Arisaemas! Arisaema Costatum is an excellent choice for any garden, proving hardy here even in unimproved heavy ‘Devon Red’ clay soil in light shade. Appearing in late Spring or early Summer, the single trifoliolate leaf is large and glossy with attractive veining. The spathe is brightly coloured, and even though it is held beneath the leaves, stands out and demands closer inspection.
The spathes have white stripes that contrast brilliantly with the maroon background, and the spadix appendage trails away in a twisted and tortuous fashion, often ending up in a coiled bunch at the base of the plant.
