Kris Plant

The Story

Plant Bio

Alocasia sanderiana is an evergreen, clumping tropical subshrub native to the wet tropical biomes of the Philippines, characterized by an upright, architectural foliage structure. The plant grows from a creeping underground rhizome, producing striking, deeply-lobed leaves that resemble the blade of a traditional kris sword.

The large, peltate leaves feature a glossy, dark metallic green to blackish-green upper surface contrasted by prominent white to yellowish-white veins and margins, with a deep reddish-purple underside. In summer and fall, it occasionally produces pairs of creamy-white spadixes enclosed by pale green, hooded spathes.

Uses & Benefits:

Highly architectural foliage with dramatic, kris-shaped leaves and contrasting white venation makes a striking indoor focal point.

Serves as a long-lived, evergreen container specimen when kept in warm, humid indoor environments.

Provides minimal outdoor ecological value in North America as it is grown almost exclusively as an indoor houseplant.

Planting

How to Grow

Select a container with exceptional drainage holes and fill it with a loose, organic-rich aroid potting mix.
Position the plant in a location that receives bright, indirect light, ensuring it is completely shielded from direct midday sun.
Water consistently to keep the soil evenly moist, but never allow the pot to sit in standing water.
Maintain high indoor humidity above 60 percent and protect the plant from cold drafts below 50 degrees Fahrenheit.

Pro Tip

Avoid heavy, dense potting soils; instead, plant in a highly aerated, loose aroid mix containing orchid bark and perlite to prevent the rapid root and corm rot caused by stagnant moisture.

Care Guide

Do

Wipe dust from the large leaves weekly with a damp cloth to maintain their glossy appearance.
Apply a balanced, water-soluble liquid fertilizer diluted to half strength monthly during the active spring and summer growth.
Prune away naturally yellowed or dead lower leaves by cutting cleanly at the base of the petiole.

Don't

Do not use heavy, water-retaining garden soils that suffocate the roots and cause rapid corm rot.
Never expose the plant to direct, hot sunlight, which quickly scorches the foliage.
Do not fertilize during the autumn and winter dormancy period when active growth stops.
Avoid exposing the plant to temperatures below 50 degrees Fahrenheit, which triggers premature collapse.
