Wedelia is a plant that has some very mixed reviews, and rightly so. While praised by some for its small, bright yellow flowers and ability to prevent erosion, it is also reviled by others for its aggressive spreading tendencies. Keep reading to learn both about growing wedelia groundcover and the dangers of wedelia propagation.
How to Grow Wedelia
Wedelia (Wedelia trilobata) is an herbaceous perennial that’s hardy in USDA zones 8b through 11. It tends to grow to between 18 and 24 inches (46-61 cm.) high. It thrives in full shade, full sun, and everything in between, but it produces flowers most impressively in full sun. Its flowers are its most appealing feature: small, yellow, daisy-like, and very prolific. It can handle a wide range of pH levels and will perform well in virtually any soil. In other words, wedelia plant care is extremely low maintenance. It will grow and thrive almost anywhere as long as the weather is warm enough. The plant is extremely tough and can handle pruning almost down to the ground. The optimal height for blossom production is about 4 inches (10 cm.).
Managing Wedelia Plants
The main aspect of wedelia plant care isn’t making sure it grows well, but rather making sure it doesn’t grow too well. Whenever wedelia stems touch the ground, they take root. This means the plant has an extremely aggressive spreading habit. While this is good news for those who want to hold down soil in otherwise barren sites that are prone to erosion (one of wedelia's most common uses), it makes it very unsuited to backyards and gardens, where it is likely to completely take over. In some states, it is classified as an invasive species. Check with your local extension office before planting. Even if it’s not an invasive species where you live, be very wary of planting this aggressive groundcover. If you do decide to plant, keep it in check by providing it with only minimal water and fertilizer. With ample amounts of either, it will truly take off and overwhelm you.
