With its low-growing habit, this plant is popular as a ground cover and brings a soft, natural atmosphere to rock or cottage-style gardens.

This article explores its key traits, cultural background, historical significance, and care tips.

Cultural Significance Around the World

Species in the Trifolium genus have long been valued across Europe for their roles in pasture and soil enrichment. Trifolium arvense, in particular, caught the attention of gardeners for its soft, decorative flower heads and compact habit.

In the UK and France, the plant’s fuzzy spikes have inspired the nickname “Bunny’s Ears” in some ornamental cultivars. These selections are now used in naturalistic garden designs and wildflower landscapes. In Japan, its soft appearance and ease of cultivation have led to increased use in rock gardens, container arrangements, and as ground cover.

Historical Background

Trifolium arvense has a long history in European agriculture. It was used as green manure and forage during Roman times, helping to maintain soil fertility and feed livestock.

Its value as an ornamental plant began to be recognized in the 20th century. The plant’s gentle form and unique flower heads led to the development and distribution of cultivars for garden use. In regions like England, where rabbit-related folklore is rich, the nickname “Bunny’s Ears” resonated with gardeners and gained popularity as a trade name.

Gardening Advice

Sunlight

Prefers full sun. Adequate sunlight ensures healthy growth and better flowering.

Watering

Tolerates dry conditions. In the ground, it rarely requires watering. For potted plants, water thoroughly when the surface soil becomes dry, but avoid waterlogging.

Soil

Well-drained, sandy or gritty soil is ideal. Add perlite or pumice to improve drainage when planting in containers.

Fertilizer

Minimal fertilization is required. Apply a small amount of slow-release fertilizer in early spring. Avoid overfeeding to prevent leggy growth.

Pruning

Remove spent flowers to encourage reblooming and maintain a tidy shape. Light trimming helps control spread.

Cold Tolerance

Fairly cold hardy. In areas with frost or snow, apply mulch at the base for protection. Above-ground parts may die back in winter but usually return in spring.

Conclusion

Trifolium arvense, or hare’s-foot clover, is a charming perennial with soft, fluffy flower spikes that have inspired the nickname “Bunny’s Ears” in some cultivated varieties. Historically used in agriculture, the plant has since gained popularity as a decorative ground cover in natural-style gardens.

With its gentle appearance and low maintenance needs, it brings a calming presence to garden spaces while preserving its ties to both agricultural heritage and modern design.
