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] While toxic under certain conditions, it is also under current review for numerous health benefits. [3]

Etymology

The name Philodendron originates from the Greek words "Philo", meaning "love", and "dendron", meaning "tree". P. hederaceum are most comfortable growing in an upwards fashion, usually up the trunk of a tree, hence, the name Philodendron. [4]

Description and cultivation

Philodendron hederaceum var. hederaceum, sold under the trade name Philodendron micans, or velvet-leaf philodendron, at the Boltz Conservatory in Madison, Wisconsin Philodendron hederaceum kz1.jpg

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. [5] Under the synonym Philodendron scandens it has gained the Royal Horticultural Society's Award of Garden Merit. [6] [7] P. hederaceum have simple leaves that are arranged in an alternate fashion, meaning single leaves are born on alternating nodes. [8]

P. hederaceum can grow with its roots both in and out of the soil, deeming it a semi-epiphyte. [9] Its uses include ornamental household decoration. It is a popular choice for such display due to its striking green coloration, spiraling, fast growing leaves, and convenient size. P. hederaceum are also easy to maintain, requiring medium sunlight and moist soil. [10] Philodendron hederaceum will eventually grow white flowers (approximately 15 years after planting). Inflorescences are rare; spike inflorescences are the most common when one does appear. They have the capacity to bear fruits as well. Philodendron fruits are typically orange, red, or white berries. [11] Philodendron are particularly skilled at eliminating toxins such as formaldehyde from the air. [12]

Toxicity

Parts of the plant are known to contain calcium oxalate crystals in varying concentrations. When ingested in large quantities, P. hederaceum cannot be properly digested. These calcium oxalate crystals are deposited in organs such as the kidneys, and can cause cardiac-related issues in humans [13] Although the plant is known to be toxic to mice and rats, the current literature is conflicting with regards to its toxicity in cats. [14] [15] [16]

Although Philodendron species can be harmful if ingested, they also have a reputation of being a source of potential therapeutic applications for medical research. [17] 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. [18]

According to the American Society for the Prevention of Cruelty to Animals, Philodendron hederaceum can cause oral irritation, a painful and swollen mouth, lips, and tongue, drooling, vomiting (except in horses), and difficulty swallowing in animals. [19]

Propagation

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. [20] 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. [21] Treatment includes moving the plant to a place of bright sunlight, but one should avoid direct sunlight. [22]

<i>Philodendron</i> Genus of flowering plants

Philodendron is a large genus of flowering plants in the family Araceae. As of June 2024, the Plants of the World Online accepted 621 species; other sources accept different numbers. Regardless of number of species, the genus is the second-largest member of the family Araceae, after genus Anthurium. Taxonomically, the genus Philodendron is still poorly known, with many undescribed species. Many are grown as ornamental and indoor plants. The name derives from the Greek words philo- 'love, affection' and dendron 'tree'. The generic name, Philodendron, is often used as the English name.
