Corsican Mint vs Oxalis Triangularis Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Corsican Mint
Mentha requienii
Corsican Mint is a very low-growing, creeping perennial herb that forms a dense mat. It is best known for its intense minty aroma, released when walked upon or crushed. The plant features tiny, rounded, bright green leaves. It's primarily grown outdoors as a ground cover, between paving stones, or in rock gardens. While it can be grown indoors, providing the right conditions can be challenging, and it may not thrive as vigorously as it does outdoors. People grow it for its fragrance and ornamental value.
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
Corsican Mint
What are the light requirements for Corsican Mint?
Corsican Mint flourishes in partial shade to full shade. Direct sunlight, especially during the hottest hours of the day, can scorch its delicate leaves. An ideal location would be under the dappled shade of trees or on a north-facing patio. If growing indoors, place it near an east-facing window or a few feet away from a south-facing window to provide bright, indirect light.
How do I care for Corsican Mint?
Corsican Mint thrives in partial shade to full shade, requiring protection from intense direct sunlight, especially during the hottest part of the day. Water regularly, keeping the soil consistently moist but not waterlogged. Proper drainage is crucial to prevent root rot. Use a well-draining soil mix amended with organic matter. Fertilize sparingly with a balanced liquid fertilizer every 4-6 weeks during the growing season (spring and summer).
How do I propagate Corsican Mint?
Corsican Mint is easily propagated through division or stem cuttings. For division, carefully dig up a mature plant and gently separate the root system into smaller clumps. Replant each clump in its own pot or directly into the ground. For stem cuttings, take 2-3 inch cuttings from healthy stems, remove the lower leaves, and place them in water or directly into moist potting mix. Keep the cuttings in a humid environment until roots develop.
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.
