Pedicularis centranthera Observations
(purple-flowered lousewort)
Submit Data Observations
Introduction to the NPN Native Species Observation Program
This member of the snapdragon (Scrophulariaceae) family is found in semi-desert, foothills, shrublands, and woodlands. Early spring walkers will find this delightful plant under and near Junipers. The flowers can be up to 2 inches and are typical of the hooded and beaked flowers of the Pedicularis genus. Flowers fade in a few weeks, the leaves rapidly grow much longer, and the entire plant dries and is gone by early summer. Leaves are about three inches long and have the typical purple cast to them. "Centranthera" refers, according to William A. Weber, to the "pointed" (Greek "centrum") and spurred "anthers".

You should record when two well-defined phenological events occur for purple-flowered lousewort:
- First bloom (FB) First select an approximately 1 by 1 meter plot for observation, and then record the date when first flowers are open in at least three places on the observed plants.
- Mid bloom (MB) Within the same 1 by 1 meter plot used for first bloom, this is the date when 50% of the flowers are open on the observed plants.
