Most orchids take their nutrients from the air, rooting to trees or rocks for stability, not for any nourishment. The bamboo orchid grows naturally in the ground, rooting in the acid soil surrounding Kilauea Volcano in Hawaii. It sends up tall flower spikes that tend to have one bloom at a time at the top. The spikes resemble bamboo, thus the name. Each size is limited to 25 copies. Free shipping and mailing within the USA. Other sizes and prices available.
