Oxalis triangularis, commonly known as the Purple Shamrock or False Shamrock, is a tuberous geophyte native to Brazil. It is known for its striking purple, triangular leaves and delicate white or pink flowers. This plant is part of the Oxalidaceae family and thrives in seasonally dry tropical climates. It undergoes a dormancy period typically during the winter months.
Oxalis triangularis prefers bright, indirect light and moderate temperatures. It should be watered when the top inch of soil feels dry, and it benefits from higher humidity levels. During its dormancy period, reduce watering and allow the plant to rest.
土壌
This plant prefers well-draining loam soil. A mix that includes peat and perlite can help ensure proper drainage. Avoid waterlogged conditions to prevent root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 10-10-10. Fertilize monthly during the growing season, but reduce feeding during the dormancy period.
植え替え
Repot Oxalis triangularis every 1-2 years or when it outgrows its pot. Repot during the early spring before the growing season begins. Use fresh, well-draining soil and a slightly larger pot.
伝搬
Propagate by dividing the tubers during repotting. Ensure each division has at least one growing point. Plant the tubers in fresh soil and water lightly until new growth appears.
剪定
Prune dead or yellowing leaves to maintain the plant's appearance and health. Pruning can be done throughout the growing season as needed.
毒性
Oxalis triangularis is toxic to pets and humans if ingested. It contains oxalic acid, which can cause symptoms such as vomiting, drooling, and difficulty swallowing. Keep out of reach of children and pets.
追加
Oxalis triangularis can be grown both indoors and outdoors. It makes an excellent houseplant due to its unique foliage and relatively easy care requirements. Ensure it receives adequate light and avoid overwatering to keep it healthy.
