May Apple vs Oxalis Triangularis Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
May Apple
Podophyllum peltatum
Mayapple is a perennial herbaceous plant typically found in woodland areas. It grows from a long, creeping rhizome. Each stem produces either a single, large, umbrella-like leaf or two leaves. The plant produces a solitary white flower that blooms in the spring, hidden beneath the leaves. This flower develops into a greenish-yellow fruit that is edible only when fully ripe. Mayapples are primarily grown for their unique foliage and woodland aesthetic. It is an outdoor plant and faces significant challenges when grown indoors.
Oxalis Triangularis
Oxalis triangularis
Oxalis triangularis is a rhizomatous perennial plant known for its striking, triangular, purple leaves that resemble shamrocks. The leaves fold up at night and reopen during the day in response to light, a phenomenon called nyctinasty. It produces small, trumpet-shaped white or pale pink flowers. It's primarily grown as an ornamental plant, both indoors and outdoors in warmer climates, for its unique foliage and interesting movement. While it can be grown indoors, it thrives with ample bright light.

❓ Frequently Asked Questions — Comparing These Plants
May Apple
What are the light requirements for May Apple?
May Apple requires shade to partial shade. Direct sunlight can easily scorch the leaves, leading to unsightly brown patches and stunted growth. The ideal location is under a deciduous tree canopy that provides dappled sunlight or in an area that receives morning sun only.
How do I care for May Apple?
May Apple thrives in moist, well-drained soil rich in organic matter. Plant in a shady location, as direct sunlight can scorch the leaves. Water regularly, especially during dry periods, keeping the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced, slow-release fertilizer to promote healthy growth and flowering.
How do I propagate May Apple?
May Apple is best propagated by division in early spring or fall. Carefully dig up an established colony and separate the rhizomes into individual sections, ensuring each section has at least one bud or growth point. Replant the divisions in a shady location with moist, well-drained soil.
Oxalis Triangularis
What are the light requirements for Oxalis Triangularis?
Oxalis Triangularis thrives in bright, indirect light. Too much direct sunlight can scorch its delicate leaves, causing them to turn brown or yellow. Insufficient light, on the other hand, can lead to leggy growth and a loss of color intensity. An east-facing window is often ideal, providing gentle morning light. A west-facing window can work if the plant is shielded from the intense afternoon sun.
How do I care for Oxalis Triangularis?
Oxalis Triangularis thrives in bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Ensure the pot has drainage holes to prevent root rot. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
How do I propagate Oxalis Triangularis?
Oxalis Triangularis is easily propagated through division. During dormancy, carefully remove the bulbs from the soil. Gently separate the bulbs, ensuring each section has roots. Plant the bulbs in fresh, well-draining potting mix. Water thoroughly and place in bright, indirect light.
