- Description
-
The native leadplant can typically be found growing in well-drained open spaces such as sandy flats and valleys, hillsides, streambanks, woodlands, glades, and prairies. It does best in sunny, sandy or rocky, well-drained soil. If grown in a shady location, it will sprawl along the ground towards a more sunny area. Its tiny purple flowers are grouped together in showy terminal spikes. The leaves are covered with short, dense hairs. This covering gives a gray tint to the leaves, making the plant appear as have been dusted with lead. Thus the common name.
Its roots can reach depths up to 4 feet and sometimes deeper. These deep roots help the plants survival during wildfires.
Insects, Diseases and Other Plant Problems: Although this plant has no serious disease or insect problems, there is some susceptibility to leaf spots, rust, canker, and powdery mildew. It needs to be protected from deer, rabbits and other herbivores.
