Know before you buy
To keep the plant blooming throughout the summer, shear it back by about one-third in mid-summer. This deadheading process encourages a fresh flush of bright golden flowers.
Yes, once the root system is established in your garden, it is highly drought-tolerant. However, you should provide regular water during its first growing season to help it settle in.
Coreopsis verticillata 'Zagreb' is considered deer resistant. While no plant is entirely deer-proof, it is generally ignored by deer compared to more palatable garden favorites.
This plant thrives in loamy, well-drained soil. Avoid planting it in heavy clay or areas that remain waterlogged, as good drainage is essential for its health.
We recommend spacing them 12 inches apart. This allows enough room for the plants to reach their mature 18-inch width while still creating a cohesive, filled-in look.
While it is primarily used for garden borders, its compact 18-inch size makes it suitable for containers. Ensure you use a high-quality, well-draining potting mix and place the pot in a spot that receives full sun.
