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.

Sunny border blue speedwell is a perennial flower that grows as a tidy clump of dark green, coarse, wrinkled leaves. In early summer, the deep-blue flowers are densely arranged on upright terminal spikes. It will rebloom if the stalks of spent flowers are cut off.
Sunny border blue veronica has been a great perennial flower at the Xeriscape Demonstration Garden. Although not quite as showy as blue salvia, it is a very dependable plant that seems to hardly be affected by Colorado's erratic weather. It has attractive blue flowers and a nice, upright shape.
Cut back the stalks of spent flowers to a set of healthy leaves to encourage rebloom. Cut old stems and leaves to ground level in late winter.
