Flower Farm Coreopsis verticillata

Yes, the blossoms shift in tone as the weather changes. You can expect a terracotta hue that deepens into a richer reddish-orange as the temperatures cool down in late summer and autumn.

Since this variety reaches a mature spread of 18 to 24 inches, you should space them about 20 inches apart to allow for proper airflow and healthy growth.

It is quite drought-tolerant once it has established a strong root system in your garden. During the first season after planting, you will need to water it regularly, but once established, it requires very little supplemental irrigation.

It performs beautifully in containers. Because of its compact 10- to 12-inch height and airy, threadleaf foliage, it makes an excellent choice for pots, provided you use a well-draining potting mix and place it in a spot that receives full sun.

This perennial is hardy in zones 5 through 9. If you live within these zones, it should return reliably each spring.

While not strictly necessary, deadheading spent blooms can encourage a tidier appearance and may stimulate a fresh flush of flowers, helping to extend the display through September.
