A most unusual and rare, epiphytic cycad from Panama, where it grows on the branches of large atlantic-coastal rainforest trees between near sea level and 1000 m (3300 ft.). Its short trunk holds a crown of up to 10, usually drooping, flat, yellowish-green leaves to 3 m (10 ft.) long. In cultivation this cycad prefers a protected spot out of full sun. In a humid, tropical climate, it will thrive in the garden right on a large, established tree. In all other climates it will do best in a wire or a large orchid basket, rooted in a coarse, very open and freely draining mixture, such as one commonly used for epiphytic orchids containing pine bark, sphagnum, peanut shells, tree fern fibers, cork pieces, charcoal, perlite, pumice or styrofoam. It must be repotted before the mixture breaks down, taking great care of the brittle roots. Z. pseudoparasitica tolerates cool periods but no frost.
