Shamrock’s uniqueness is due to the corms, which serve as a substitute for the regular root ball in the division. This is what you’ll plant; it resembles a little pine cone. These corms are great because they may be planted in any orientation.

Planting the corms sideways, upwards, or downwards will not affect the shamrock plant’s ability to thrive.


You can use potting soil and sand as a substrate for planting the corms after you have gathered them. Do not bury them deeply, but make sure the container is well-drained. Keeping the medium moist is critical to the success of shamrocks, so you don’t want to overwater them.

Corms can be stored in an 8-inch nursery pot, which can hold up to four shamrock divisions. The blunt face should be up, and the tapering end should be down at a depth of two inches, even though shamrocks aren’t particular about how they are planted. That manner, the part responsible for leaf production will be located at the very top.

When establishing shamrock divisions, where should they be located? When it comes to starting any kind of plant, the greenhouse is always the best option because it shields the delicate divisions from the harsh and unpredictable weather. It is best to place shamrock plants in a well-lit area that isn’t exposed to direct sunshine.

This plant, often known as a purple shamrock, is commonly offered during St. Patrick’s Day as a houseplant. Bulb division is a terrific technique to spread your purple shamrocks.

About Purple Shamrock

Shamrock leaves are three-leaved, and look like clover. The purple-shaded triangle forms on the leaves give this plant its scientific name, triangularis. The lavender flowers contrast with the reddish-purple foliage. Native to tropical Brazil and found in damp places at high elevations, purple shamrock is found in a variety of habitats. Purple shamrock is a common houseplant because of its sensitivity to cold temperatures.


During its dormancy, the purple shamrock can go for up to three months. The plant goes into “sleep mode” for a length of time during dormancy. For nearly three months, purple shamrocks are dormant. Signs of dormancy include a loss of vigor and a decline in the number of leaves on the plant. Reduce the amount of water and fertilizer you give your plant and keep it in a cool, dark place during this period. Dormancy has come to an end, as evidenced by the emergence of new growth.


Bulbs of Oxalis triangularis are the source of the plant’s reproduction. It is suggested by the University of Vermont Extension that bulbs be divided as soon as fresh growth appears at the conclusion of plant dormancy. Remove the bulbs from their pots and remove the smaller side bulbs. Baby bulbs can be planted right now because they’ve already been grown. Keep the soil always moist by replanting them slightly below the surface.

Plant Care

Do not let temperatures go below 30 degrees Fahrenheit if your shamrocks are grown in the garden. They should be stored in a cool spot until spring. In full sun and moist soil, the purple shamrock thrives, although it can also thrive in shaded areas. During the day, temperatures should range from 70 to 75 degrees Fahrenheit, and at night, they should range from 50 to 65 degrees.
