Plant Information

Leptinella is a creeping perennial ground cover that spreads quickly by rhizomatous runners just under the soil surface. Leaves are feathery or fern-like with colors ranging from grayish green to bright green with gray, purple and black tints. Flowers are tiny button-like heads without the petal-like ray florets usually associated with daisies. Colors of flowers range from white to yellow or even black.
Leptinella stays evergreen during the majority of Portland’s winters and grows well in shade or sun. Once established, Leptinella forms dense mats that can withstand regular foot traffic. This ground cover looks great in many different types of gardens, such as fairy, Japanese, and woodland. In terms of function, Leptinella is useful as a durable lawn substitute, living patio, or planting between pavers
or along the edges of pathways

Culture: Thrives in moist, well-drained soil that is rich in organic matter. Tolerates full sun and full shade, but best in part shade. Hardy in zones 4-10.
Maintenance: Regular water and annual fertilizing. Transplants easily if bare spots arise due to drought or cold.
Additional qualities: Evergreen. Tolerates light foot traffic.
Pests and Disease: Few insect and disease problems. May die off in areas where soil is too compact or dry and hot.
