About
Philodendron hederaceum, 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. While toxic under certain conditions, it is also under current review for numerous health benefits.
How to grow it
Layering and cutting are two of the favored techniques when it comes to propagating P. hederaceum. It is best to propagate during the spring and summer. To begin propagation, locate an axillary bud and cut a branch directly beneath it. This branch should then be placed in soil or water with a small amount of activated charcoal. Treatment includes moving the plant to a place of bright sunlight, but one should avoid direct sunlight.
Safety
Parts of the plant are known to contain calcium oxalate crystals in varying concentrations. These calcium oxalate crystals are deposited in organs such as the kidneys, and can cause cardiac-related issues in humans. Although the plant is known to be toxic to mice and rats, the current literature is conflicting with regards to its toxicity in cats.
Although Philodendron species can be harmful if ingested, they also have a reputation of being a source of potential therapeutic applications for medical research. This reputation is due to the presence of terpenoids and flavonoids, natural compounds that are of interest because of their biological abilities in acting as an antioxidant, anti-inflammatory, and disease preventative.
