Product Information

Oxalis triangularis is a very beautiful plant, with small, trumpet-shaped flowers that come in white, light pink, and lavender colors. The flowers bloom in the spring and summer and last a good few weeks. Each stem will have three triangular leaves, which look like three butterflies sitting nose-to-nose. Most similar plants of the species will have green foliage of the same shape, but the Oxalis triangularis is special due to its unique, eye-catching purple leaves. Next, add a layer of potting mix to the pot, leaving enough room for about 1 inch of potting soil above your plant’s bulb and another inch or so of space between the top of the soil and the top of the container.

Oxalis triangularis plants are easy to care for, and can live for a long time—up to 100 years! This means they often become “heirloom plants”, passed down from generation to generation, in most cases becoming part of a much-loved family tradition. Place your plant’s bulb or rootball on top of the bottom layer of potting mix. Fill in around and over the roots and bulb with potting mix. Gently pat the potting mix down. Oxalis Triangularis are highly “photophilic”, which means their flowers and leaves react to the amount of sunlight they are given. In bright light, they open wide. In little or no light, the closed flowers and leaves look like butterflies. When selecting or creating a potting mix for Oxalis triangularis, the most important thing to remember is that the soil must be well-draining and should have good aeration. Any potting mix that is too heavy will hold too much moisture and put the plant at risk of root rot. Apply a balanced liquid houseplant fertilizer diluted to half-strength every one to two weeks. For best results, add the fertilizer to your regular watering routine when appropriate. Do Oxalis Triangularis Plants Need to Be Pruned?

Moderate or average indoor humidity is fine. In exceptionally dry conditions, you can increase humidity by running a humidifier, misting the plant once a week, or adding a humidity tray with pebbles and water below the plant. When the flowers die, prune them off to keep them from causing other problems, such as rot or disease. During the plant’s dormant period, trim away and remove dead foliage. Neem oil is a natural pesticide. Follow the instructions on the label for diluting the oil, then spray it all over your plant, making sure to get under the leaves and on the stems. Before you cover your plant, test the oil in one area to be sure the oil is properly diluted. Neem oil deters bugs and prevents bugs from growing. It will take a few days to actually kill the bugs, but is proven to be very effective. Water your plant about once every week, and water it very lightly/gently. The stems of this plant are delicate and can easily break if treated roughly. Only water when the top inch or so of the soil is dry. Too much water can cause root rot, and too little water can cause the plant to go dormant, which we’ll discuss later.

You’ll need a rich and well-draining potting mix, a container with drainage holes, and a location in your home that receives plenty of sunlight. Somewhere near a south-facing window would be ideal.

Water the plant thoroughly, until water drains from the bottom of the pot. Allow all excess water to drain before placing your plant in the desired location. Repot bulbs while the plant is dormant, but try to do it toward the end of its dormancy. The plant needs time to rest, and the stress of repotting and replanting isn’t good for a plant freshly out of dormancy. Allow it some time to recover. Propagating Oxalis Triangularis Keep this plant somewhere it can get a lot of indirect sunlight. While direct sunlight can be too harsh for this plant in hot climates, the leaves do require medium light levels to produce energy. If the lighting conditions aren’t bright enough, your plant won’t grow as robustly, and it will tend to become unkempt and leggy, with uneven growth and flopping stems.

Plenty of nutrients in your plant’s potting soil will encourage growth and flowers. You should fertilize an Oxalis triangularis plant during the growing season only.A dormant Oxalis triangularis requires a different care routine than a non-dormant plant. Once your plant has gone dormant, remove dead foliage. Dead and damaged flowers and leaves cause stress to the plant and take up energy that could be directed elsewhere. By removing these stressors, air can flow better through the plant and encourages better energy distribution, which results in a healthier, stronger plant. You can feel the potting mix with your fingers to test the moisture level or use a moisture probe, which simplifies the watering process (especially during dormancy). Conversely, plants that receive less sunlight or that are placed in cooler or more humid environments will require less frequent watering. The Oxalis triangularis can occasionally go dormant, typically after the growing season and when the plant is experiencing temperature extremes. During this time, the plant may look like it has died. Foliage will droop and the flowers won’t open to the light. Allow this to happen; it doesn’t always mean that your plant has died! Propagation is much like the repotting process. Just gently remove the plant from the pot and separate it into sections. Try not to cause too much damage to the roots; be sure you’re getting the whole root clump, bulbs, and all. The roots might be tangled together; if this is the case, use clean scissors to cut them apart, trying to keep as much of the root intact as possible.
