Oxalis oregana, commonly known as Redwood Sorrel, is a perennial plant native to the moist, shaded understories of coastal redwood forests in North America. It features trifoliate leaves that resemble clover and delicate pink to white flowers. The plant goes dormant in the winter and re-emerges in the spring.
Oxalis oregana thrives in moderate temperatures and prefers bright, indirect light. It requires consistently moist soil and benefits from a humid environment. Avoid direct sunlight as it can scorch the leaves.
土壌
This plant prefers well-draining loamy soil that retains moisture but does not become waterlogged. A mix of garden soil with organic matter like compost works well.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize once a month during the growing season to support healthy growth.
植え替え
Repot Oxalis oregana every 2-3 years or when it outgrows its container. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repot in the spring before the growing season begins.
伝搬
Propagate by dividing the rhizomes in early spring. Carefully separate the rhizomes and plant them in individual pots or directly in the garden. Keep the soil moist until new growth appears.
剪定
Pruning is generally not required for Oxalis oregana. Remove any dead or yellowing leaves to maintain the plant's appearance.
毒性
Oxalis oregana contains oxalic acid, which can be toxic to pets and humans if ingested in large quantities. Symptoms may include vomiting, drooling, and difficulty swallowing. Keep out of reach of pets and children.
追加
Oxalis oregana can be sensitive to overwatering, so ensure the soil is moist but not soggy. It can also be grown as a ground cover in shaded garden areas.
