Plant Profile: Coreopsis auriculata

Coreopsis auriculata, commonly referred to as mouse-eared tickseed, is a native perennial belonging to the Asteraceae family that spreads through stolons. This plant is easy to cultivate and requires minimal upkeep, making its prolonged flowering period particularly appealing for garden borders and beds, where it tends to establish itself naturally. While it handles humidity well and can endure some dry spells, it is not as drought-resistant as certain other Coreopsis varieties. Additionally, it is known for its resistance to deer damage.

Although deadheading spent flower stalks can be a laborious task in larger plantings, doing so encourages further blooming. To maintain a tidy appearance and promote a second bloom in the fall, shear the plants in mid-summer. Given optimal growing conditions, Coreopsis auriculata gradually spreads, creating a visually pleasing mass planting. However, if you wish to control its spread, rest assured that it is easy to manage. In spring, you can divide clumps to either enhance your garden or share with friends.

The 'Nana' variety is a compact selection that typically reaches heights of 6 to 9 inches, making it ideal for the front of borders or along edges. It is important not to propagate this cultivar from seeds collected from your own plants, as they will not produce true-to-type offspring. Instead, consider dividing or taking cuttings for propagation.

This plant was honored as the 1991 NC Wildflower of the Year, a recognition managed by the North Carolina Botanical Garden with financial backing from the Garden Club of North Carolina.

In terms of pests and diseases, Coreopsis auriculata does not face significant issues; however, crown rot may develop if it is planted in consistently moist, poorly drained soils. In fertile and wet conditions, the plant may spread excessively and can experience foliage burn during hot summer months.
