Do oxalis come back every year?

As a gardening and landscaping expert, I can provide you with detailed information about oxalis and whether or not it comes back every year.

Oxalis, also known as purple shamrock or purple oxalis, is a perennial plant, which means it has the ability to come back each year. However, its growth pattern is such that it goes dormant during the winter months. This dormancy period is a natural part of the plant’s life cycle and is necessary for its overall health and longevity.

During the winter, purple oxalis will start to show signs of wilting and yellowing of the leaves. This is a clear indication that the plant is preparing for dormancy. It is important to note that this wilting is not a sign of distress or poor care, but rather a natural response to the changing seasons.

To ensure the survival of your purple oxalis during the winter months, it is recommended to dig up the plants and store them indoors before the first frost of fall. This will protect the bulbs from freezing temperatures and prevent any potential damage.

To store the plants, gently dig them up, taking care not to damage the bulbs. Shake off any excess soil and allow the bulbs to dry for a few days. Once dry, you can place them in a container or paper bag with some dry peat moss or vermiculite. Make sure to label the container with the name of the plant and the date of storage.

Store the container in a cool, dark location, such as a basement or garage. Avoid exposing the bulbs to direct sunlight or extreme temperature fluctuations. Check on the bulbs periodically throughout the winter to ensure they are not drying out or rotting.

In the spring, as the weather starts to warm up and the danger of frost has passed, you can replant the purple oxalis bulbs outdoors. Choose a location that receives partial shade to full sun and has well-draining soil. Plant the bulbs about 2-3 inches deep and space them about 4-6 inches apart.

When the new growth starts to emerge, you can resume regular watering and fertilizing. Purple oxalis prefers consistently moist soil, but be careful not to overwater as this can lead to root rot. Fertilize the plants with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season to promote healthy growth and vibrant blooms.

It is important to note that purple oxalis can be invasive in some regions, so it is recommended to check with your local garden center or extension office before planting it in your garden. Additionally, keep in mind that oxalis is toxic to pets if ingested, so take appropriate precautions if you have furry friends around.

Oxalis is a perennial plant that does come back every year. However, it goes dormant during the winter months and requires proper care and storage to ensure its survival. By digging up the plants and storing them indoors before the first frost, you can maintain the health and longevity of your purple oxalis for years to come.
