Syngonium podophyllum, commonly called arrowhead vine, is native from Mexico to Ecuador. It is an evergreen climbing vine that typically grows to 3-6’ long.

Juvenile leaves (to 5.5” long) are ovate with heart-shaped bases and sometimes with silver variegation. Leaves mature to arrow shape. Later leaves become pedate (to 14” long), each with 5-11 leaflets. Tiny green to greenish-white flowers on a spadix are surrounded by a greenish-white spathe (to 4.5” long). Flowers are born in groups in the leaf axils. Flowers give way to brown-black berries. Plants rarely flower in cultivation. Synonymous with Nephthytis triphylla.
