Oxalis Versicolor
Often called the "Candy Cane Sorrel," this South African gem is a favorite among bulb collectors for its whimsical, striped appearance. Before the flowers fully unfurl, they look exactly like tiny peppermint sticks tucked into a bed of green clover. It is a cheerful winter-growing plant that brings a touch of holiday magic to windowsills and rock gardens just when most other plants are going dormant.
The Oxalis versicolor is a master of "Nyctinasty"—the biological rhythm that causes plants to close their petals at night. This isn't just for show; it protects the pollen from dew and keeps the flower's reproductive organs warm during chilly South African nights!
To grow an Oxalis Versicolor plant, you can follow these steps:


To fertilize the Oxalis Versicolor plant, use a balanced liquid or granular fertilizer with an N-P-K ratio of 10-10-10 or similar. Dilute the liquid fertilizer as per the instructions on the packet or use the recommended amount of granules.
Apply the fertilizer during the plant's active growing season, typically from spring to early fall. Avoid fertilizing during the winter months when the plant goes dormant.
Before applying the fertilizer, make sure the soil is moist. You can water the plant the day before fertilizing to ensure the soil is adequately hydrated.
Carefully follow the instructions on the fertilizer packaging for the correct amount and method of application. Generally, you can either sprinkle the granules evenly around the base of the plant or mix the liquid fertilizer with water according to the recommended dilution and pour it onto the soil.
Avoid getting the fertilizer directly on the leaves or stems of the plant as it can cause burning or other damage.
After fertilizing, water the plant lightly to help the nutrients settle into the soil and prevent any potential root burn.
Repeat the fertilization process every four to six weeks during the growing season or as directed by the specific fertilizer's instructions. Monitor the plant's response to the fertilizer and adjust the frequency or dosage if necessary.
Remember to always read and follow the instructions provided by the fertilizer manufacturer, as different products may have slightly varied application methods and timing recommendations.
When selecting soil for Oxalis Versicolor, it is important to choose a well-draining soil that retains moisture without becoming waterlogged. This plant prefers a slightly acidic to neutral pH, ideally ranging between 6.0 and 7.0. The soil should be rich in organic matter and nutrients to support healthy growth.
A recommended soil mix for Oxalis Versicolor could include a combination of peat moss or coconut coir, perlite or vermiculite, and a high-quality potting mix or garden soil. These components help ensure good drainage and aeration, preventing waterlogging and root rot.
Peat moss or coconut coir is beneficial in retaining moisture, which is particularly important for Oxalis Versicolor, as the plant prefers slightly moist conditions. The perlite or vermiculite improves drainage by preventing the soil from compacting and becoming too dense.
To further enrich the soil, you may consider adding compost or well-rotted organic matter that will provide additional nutrients for the plant's growth. This organic matter helps improve the soil structure, encourages beneficial microbial activity, and provides essential nutrients for overall plant health.
When potting Oxalis Versicolor, ensure that the container has drainage holes at the bottom to allow excess water to escape and prevent the soil from becoming waterlogged. It is also advisable to avoid using heavy clay-based soils that tend to retain too much water, as this can lead to root rot.
Regularly monitor the moisture levels in the soil and water the plant when the top inch of soil feels dry. Taking care not to overwater or underwater is essential for maintaining optimal soil conditions, which will promote healthy growth and vibrant foliage for your Oxalis Versicolor plant.
