Clever Gardening Technique

Control African Daisies
Although they create swaths of color with bright yellow and orange flowers, African daisies (Dimorphotheca sinuata or D. aurantiaca) have shown invasive tendencies in desert areas. Their seeds are easily transported by wind. With housing developments adjacent to mountain preserves and natural areas, African daisies may out-compete the native wildflowers that creatures in the region have relied upon for centuries. They also take over wildflower plantings in landscapes. In a few years, there will be a monoculture of African daisies in your wildflower meadow. Pull the plants before they go to seed. Next fall, scatter seeds for native alternatives, such as desert marigold.
