A species from wet tropical forests of Colombia, where it grows as an epiphyte, perching on tree branches and climbing or creeping along them, using its fleshy roots to cling to the bark. The plant produces heart shaped, dark green, velvety leaves, with prominent, pale green veins. In ideal growing conditions in cultivation, the plant can grow to 1.2m and have leaves 90cm across. It resembles some of the other anthurium species in appearance but is identifiable by its four-sided leaf stalks. The plant produces flowers consisting of a pale green sheath-like spathe, surrounding a green spadix or column. The flowers are not especially ornamental, and it is the spectacular foliage that is the main feature of this plant

How to Grow

Cultivation

A light, open, well-drained growing medium such as a proprietary orchid compost is required, along with warmth, bright, but indirect sunlight and high atmospheric humidity for the plant to do well. Watering the plant with rainwater or filtered water such as by reverse osmosis, at room temperature is beneficial, as it can be sensitive to the build-up of chemicals dissolved in hard tap water, if used. The compost should be allowed to become dry before thoroughly watering again. Plants should not be allowed to sit in water for long periods, which can cause the roots to rot. Feeding with a proprietary orchid fertiliser is beneficial during the growing season April to September. See Anthurium and Houseplant cultivation for further advice
