Care Guide for Oxalis triangularis ‘Plum Crazy’

Light Requirements

Oxalis triangularis ‘Plum Crazy’ thrives in filtered bright to medium light, preferably in the morning. It should be kept away from direct sunlight, as it grows best when it’s not exposed to intense light. The glass in windows filters out a lot of the light intensity, reducing the risk of burning the plant. To promote even foliage growth, rotate the pot every two weeks.


When it comes to watering Oxalis triangularis ‘Plum Crazy,’ it’s important to strike a balance. It prefers consistently moist soil but doesn’t tolerate waterlogged conditions. The general rule of thumb is to provide the plant with 0.5 cups of water approximately every 9 days when it doesn’t receive direct sunlight and is potted in a 5″ pot. Remember to adjust watering frequency based on the specific conditions in your home. It’s always a good idea to check the moisture level of the soil before watering.

Humidity and Temperature

Oxalis triangularis ‘Plum Crazy’ appreciates a humid environment. Misting the foliage or using a pebble tray filled with water can help create a slightly more humid atmosphere. Keep the plant in normal room temperatures between 65-75 degrees Fahrenheit. It cannot tolerate temperatures above 80 degrees, so avoid placing it in areas with excessive heat, such as near radiators or vents.


To promote healthy growth, feed Oxalis triangularis ‘Plum Crazy’ once a month during the spring and summer months with an all-purpose houseplant fertilizer. Follow the instructions on the fertilizer packaging for proper dosage.

Propagation of Oxalis triangularis ‘Plum Crazy’

If you want to expand your collection of Oxalis triangularis ‘Plum Crazy’ or share it with fellow plant enthusiasts, propagation is the way to go. There are several methods you can use to propagate this variety:

  1. Division: During the plant’s dormancy period, when it dies back, the bulbs can be repotted into separate pots. Plant the bulbs 1-2 inches deep in moist potting mix. If multiple bulbs are planted together, space them out. Once the dormancy period ends, new plants will sprout from the bulbs.

  2. Offsets: This variety produces offsets around its base. When offsets reach about 3/4″ in diameter, they can be removed from the mother plant with sharp pruning shears. These offsets should then be repotted in fresh potting mix and placed in a humid area until new growth emerges. Once the new growth appears, they can be moved back to the regular growing area.

  3. Bulbs: Healthy and well-established bulbs are suitable for propagation. If the top growth starts to encroach on the bulb, the bottom of the bulb should be pruned back. The bulb should then be placed in a pot with rich soil and watered until water drains from the bottom. After being placed in a sunny window for 4-6 weeks, allowing new leaves to appear, the bulb can be moved back to the growing area.
