Philodendron hederaceum,[1] the heartleaf philodendron (syn. Philodendron scandens) is a species of flowering plant in the family Araceae, native to Central America and the Caribbean which is common in the houseplant trade. Philodendron hederaceum var. hederaceum, the "velvet philodendron," is a subspecies which is in the houseplant trade under its previous name of Philodendron micans.[2]
It is an evergreen climber growing to 3–6 m (10–20 ft), with heart-shaped glossy leaves to 30 cm (12 in) long, and occasionally spathes of white flowers in mature plants. With a minimum temperature requirement of 15 °C (59 °F), in temperate regions it must be grown under glass or as a houseplant.[3] Under the synonym Philodendron scandens it has gained the Royal Horticultural Society's Award of Garden Merit.[4][5]
Parts of the plant are known to contain calcium oxalate crystals in varying concentrations. Although the plant is known to be toxic to mice and rats, the current literature is conflicting with regards to its toxicity in cats.[6][7][8] Its possible toxic effects on humans are currently unknown although likely very mild if not harmless.[9]
