Anthuriums

Anthuriums, like bromeliads, orchids and pinguins, are epiphytes, a nonparasitic plant that grows on another plant, but gets its nourishment from the air - thus, the name “air plant”.

Anthuriums can grow on the ground, on rocks, or up in trees. The local varieties are Anthurium cordatum (heartleaf), Anthurium crenatum (scrub brush) and a hybrid of these two.

The heartleaf is more common in moist forest areas. It produces beautiful foliage that sometimes is home for tree snails and nests of wasps called Jack Spaniards. The heartleaf anthurium produces a long pointy reddish-green stalk-like flower.

The scrub brush anthurium has long green leaves with seasonal red fruit. The dried dead leaves have been used in the past to scrub pots and pans. They are just as effective as the commercial pot scrubbing products used today, plus they have the advantage of being easily disposable, non-rusting and biodegradable.

The heartleaf anthurium is common in the Lesser Antilles. The scrub brush anthurium is found in the Greater Antilles. They seem to have met on the islands of St. John and Tortola to produce a hybrid variety (anthurium selloum) which is only found on these two islands. It is sterile and cannot reproduce. The hybrid looks just like what you would expect a mixture of the two parent varieties to look like. See if you can identify one.

Anthuriums (Araceae) - from NPS sign Reef Bay Trail
(Anthuriums) Arum Family

There are 500 varieties of these plants native to Central and South America and the Caribbean Islands. Anthuriums are perennials that grow on the ground or up in trees. The local variety along the trail are anthurium acaule, (scrub brush) and anthurium cordatum, (heart leaf). Both are foliage species not of the flowering group of anthuriums.

Scrub brush has long green leaves with seasonal red fruit. Dead leaves form a lacy "skeleton" that is used traditionally to scrub pots and pans.

Heart leaf produces beautiful foliage that sometimes is home for nests of jack-spaniards (wasps) and tree snails. The pistil of this plant is a long, rough green "whip."
