Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.

  • Description

  • Notes

Bush penstemon forms a bushy, woody sub-shrub that forms a rounded mound up to 3 feet tall. Fragrant flowers emerge in clusters near the tops of branches, and are pale pink to white with deeper pink reverse. Blooms most heavily in May, and than sporadically through October. Flowers are reminiscent of phlox. Narrow bright green leaves. A Utah native. Attractive to native bees.
Grow in full sun and well drained soil. Will grow in sandy soils. Will not tolerate over-watering. Extremely drought tolerant.
