Mouse-ear tickseed

Coreopsis auriculata L., commonly known as mouse-ear tickseed, is a perennial herbaceous plant belonging to the Asteraceae family. This species is widely recognized for its ease of cultivation and its vibrant, daisy-like yellow flowers that bloom throughout the late spring and summer months, making it a valuable asset for various garden settings.

The native habitat of this species is North America, where it thrives in woodlands, meadows, and open rocky sites. Due to its origin in diverse climatic environments, it is exceptionally adaptable. It is now cultivated extensively across various temperate regions worldwide, serving as an important component in native garden projects and ornamental landscape designs.

Botanically, the plant features a low-growing habit, typically reaching heights between 20 and 45 cm. It produces basal leaves with distinctive, ear-like lobes, which serve as a diagnostic feature for the species. The inflorescences consist of solitary, bright yellow flower heads that rise on slender stems, attracting various pollinators, including bees and butterflies, into the garden environment.

Cultivation success relies on providing well-draining soil and a position with full to partial sun exposure. Coreopsis auriculata is relatively drought-tolerant once established but performs best when receiving consistent moisture during its peak flowering season. Maintenance tasks include deadheading spent blooms to promote secondary flowering and dividing established clumps every few years to maintain plant vigor.

Regarding its utility, the species is primarily used as a groundcover, in border plantings, and within rock gardens. It is susceptible to common garden pests like aphids and spider mites, and in overly humid conditions, it may suffer from powdery mildew. Proper spacing to ensure adequate airflow and avoiding overhead irrigation are recommended practices to mitigate these potential health issues.

• Thrives in a variety of soil types ranging from sand to clay-loam.
• Can be propagated easily by division or seed sowing in autumn.
• Excellent choice for wildlife-friendly and sustainable gardens.
