Anthurium magnificum

Anthurium magnificum is an evergreen climbing plant from Colombia. It belongs to the arum family, Araceae. In wet tropical forests, it grows on tree branches. This makes it an epiphyte, a plant that uses trees for support. Its fleshy roots grip bark as its stems climb or creep. Gardeners grow it for its leaves rather than its flowers.

The RHS lists a mature height of 3.3–4.9 feet (1–1.5 metres). Its stated spread is 0.3–1.6 feet (0.1–0.5 metres). The profile also describes plants reaching 3.9 feet (1.2 metres) under ideal conditions. Full size may take five to ten years. The heart-shaped leaves have a dark green, velvet-like surface. Pale green veins stand out against the darker blade. Leaves can reach about 3 feet (0.9 metres) across. Four-sided leaf stalks help tell this species from similar anthuriums. Its flowers have a green spadix within a pale green spathe. These blooms offer less visual interest than the leaves.

This tropical plant needs warmth and high air humidity. Give it bright light without direct sun. The RHS rates it H1A, for year-round growing under glass. Keep temperatures above 59°F (15°C). It suits a house, warm greenhouse, or conservatory. Use a loose growing mix that drains well, such as orchid compost. The RHS lists sandy or loamy media with acid or neutral pH. Its growing guide says to let the compost dry before watering thoroughly. Do not leave the pot standing in water. Long periods in water can cause root rot.

Rainwater or filtered water at room temperature suits this plant. Dissolved chemicals from hard tap water can build up and cause harm. The RHS suggests orchid fertiliser from April through September. It needs no routine pruning. Growers can make new plants from stem-tip or leaf-bud cuttings. Its main role is as an indoor foliage plant. The large leaves and pale veins provide its chief display.

The RHS reports few disease problems under suitable growing conditions. Red spider mites, mealybugs, and scale insects may attack it. Check for these pests while caring for the leaves and stems. This plant is harmful to people and pets if eaten. Contact may also irritate skin or eyes, or cause an allergic reaction. Wear gloves and suitable protection when handling it.
