Monstera acuminata

Monstera acuminata is an evergreen vine in the arum family, Araceae. Its native range runs from Mexico through Central America. It grows in a wet tropical climate. The RHS also calls it the shingle plant. This compact plant can climb or trail. Gardeners grow it indoors for its dark green leaves. It suits homes, conservatories, and greenhouses where warmth and shelter are available.

In cultivation, it reaches about 3.3–4.9 feet (1–1.5 metres) tall. Its spread is about 1.6–3.3 feet (0.5–1 metre). Growth is slow, and full size may take 10–20 years. The leaves are small, narrow, glossy, and heart-shaped. Many holes break up each leaf surface. These holes, called fenestrations, have oval or teardrop shapes. The plant keeps its leaves through the year. Its trailing habit and modest size suit container growing.

Plants in pots seldom flower, so foliage provides the main display. When blooms do appear, they have cream-yellow spathes. Do not expect flowers as a regular part of indoor growth. Give the plant bright light without direct sun under glass. The RHS also lists partial shade as a suitable position. Moderate to high air humidity supports its cultivation. Choose a sheltered place rather than an exposed site.

Use a peat-free potting mix with a loam base. Keep the mix moist, but allow water to drain freely. Water during the growing season, then keep it just moist in winter. Apply a balanced liquid feed each month during active growth. The RHS lists acid, neutral, and alkaline soil as suitable. Its UK hardiness rating is H1B. It can spend summer outside, with temperatures in the 50–59°F (10–15°C) range. Grow it under glass for protection outside suitable summer conditions.

Scale insects and glasshouse red spider mites may attack this plant. The RHS reports few disease problems. It lists the species among low-maintenance plants for indoor and subtropical settings. Propagation options include seed, root-tip cuttings, leaf cuttings, and summer layering. The plant is harmful to people who eat it. It can also irritate skin and eyes. Wear gloves and other protective gear when handling it. Treat it as an ornamental plant, not a food crop.
