The Delicate Delight of Redwood Sorrel: A Guide to Oxalis Oregana

For those seeking a touch of elegance in their home greenery, the redwood sorrel, or Oxalis oregana, might just be the perfect answer. This charming little perennial, native to the coastal forests of western North America, boasts delicate clover-like leaves and dainty white or pink blossoms. But its appeal goes beyond aesthetics – redwood sorrel thrives in shady corners, making it ideal for brightening up low-light areas in your home.

Having successfully cultivated these little gems in my own flat, I’m here to share my experience and guide you through the joys of caring for Oxalis oregana.

How to Care for Oxalis Oregana?

Redwood sorrels are relatively low-maintenance plants, but understanding their basic needs is key to keeping them happy and thriving. Here’s what you need to know:

  • Light: Redwood sorrels prefer dappled sunlight or indirect light. Avoid harsh, direct sunlight, which can scorch the leaves.
  • Water: These plants enjoy consistently moist soil, but not soggy. Water deeply when the top inch of soil feels dry, and allow excess water to drain freely.
  • Soil: A well-draining, fertile potting mix is ideal. Opt for a mix rich in organic matter, like compost or peat moss.
  • Temperature: Redwood sorrels prefer cooler temperatures, ideally between 55°F and 70°F (13°C and 21°C). Avoid placing them near heat vents or drafty windows.
  • Humidity: Moderate humidity is beneficial, especially in drier climates. Mist the leaves occasionally or place the pot on a pebble tray filled with water.

How Many Oxalis Oregana in a Flat?

There’s no magic number when it comes to how many Oxalis oregana you can have in your flat. It ultimately depends on the size of your space and the desired effect.

  • Single statements: For a pop of color in a small corner, a single plant in a well-proportioned pot can be very effective.
  • Clustered effect: Group several plants of varying sizes in a larger pot to create a lush, cascading effect.
  • Hanging baskets: Redwood sorrels can also thrive in hanging baskets, their delicate foliage trailing gracefully. Consider the weight of the basket when planting multiple Oxalis oregana.

Remember, these plants spread through underground rhizomes. So, if you plant several in a single pot, they’ll naturally fill out the space over time.

How to Propagate Oxalis Oregana?

The beauty of Oxalis oregana is its ease of propagation. Here are two methods you can try:

  • Division: During repotting, you can gently divide the main clump into smaller sections, each with a healthy bud or rhizome. Plant each division in its own pot with fresh potting mix. Water thoroughly and maintain consistent moisture until new growth appears.
  • Bulblets: Redwood sorrels produce tiny bulbils at the base of the leaves or along the rhizomes. Carefully remove these bulbils and plant them in shallow pots with moist soil. Keep them in a warm, well-lit location (indirect light) and mist regularly until they sprout.

Additional Tips for Redwood Sorrel Success

  • Fertilizer: During the growing season (spring and summer), a light application of liquid fertilizer diluted to half strength every four to six weeks can benefit your redwood sorrel. Opt for a balanced fertilizer formulated for houseplants.
  • Deadheading: Regularly remove spent flowers to encourage continued blooming. Simply pinch off the flower stalk at its base.
  • Dormancy: Redwood sorrels may go dormant during the winter months. Reduce watering frequency and avoid fertilizing during this period. New growth should resume in spring.

With a little care and attention, Oxalis oregana will reward you with its delicate charm and enduring presence. So, why not bring a touch of the redwood forest into your own home?
