Groundcovers
Leptinella squalida ‘Platt's Black’
Platt’s Black Brass Buttons
Leptinella squalida 'Platt's Black' is an attractive ground cover known for its unique dark foliage, which creates a dramatic contrast in the garden. The fern-like leaves range from deep purplish-black to dark green, providing year-round interest and adding a rich, moody tone to the landscape. In late spring to early summer, small, button-like yellow-green flowers appear, though they are often overshadowed by the bold foliage, which is the plant's main attraction.
