Use the plant water needs as a guideline. Actual plant water needs will vary for several reasons, including weather conditions, soil type, sun exposure, root depth, wind and elevation. Adjust your watering schedule as needed to meet the plants' needs at your site. Water recent transplants more often than established plants.

Bridges' penstemon is a perennial flower native to the southwestern United States. It is a somewhat shrubby, long-lived plant with tufts of dark, evergreen foliage.
The slender trumpet-shaped flowers are orange-red and bloom prolifically through the hot summer months. While most penstemons bloom early, Bridges' Penstemon will flower later in the summer. This little-known southwestern native wildflower is noted for having a longer life span than most other penstemons.
Bridge's penstemon is a good choice for a hot sunny location. It has grown well at the Xeriscape Demonstration Garden. The show of scarlet flowers is quite impressive and is a welcome sight later in the growing season.
This plant needs little to no maintainence. It may be pruned lightly in the spring to remove any winter-kill and to create a more compact plant.
