Threadleaf coreopsis is a long-blooming drought tolerant perennial that attracts butterflies and goldfinches to the garden. Add a few long time favorites and colorful new introductions to your landscape.
Moonbeam and Zagreb are long time favorites. These hardy plants produce yellow daisy-like flowers on compact plants and are hardy in zones 3 to 9.
Ladybird produces red flowers on compact plants. Hardy in zones 5 to 10, it provides a nice spot of color in the garden.
Buttermilk has light yellow flowers and grows 15 inches tall. It is hardy in zones 5 to 10 and like the other threadleaf coreopsis it prefers full sun and well-drained soil.
Consider buying just a plant or two when trying new introductions in the garden. You can evaluate how they perform in your garden before investing in more plants.
A bit more information: Showstopper coreopsis has bright rose-pink flowers on larger 20 inch tall plants. It is larger than Limerock and appears to be hardier.
