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

Whipple penstemon has distinctive magenta flowers with conspicuous white beards. It blooms a bit later than other penstemon, usually in July and August. Its foliage is green and just slightly hairy; grows 12 to 24 inches tall and half as wide. A Utah native.
Whipple penstemon tolerates richer soils and a bit more shade than other penstemons, though it still needs well-draining soils. It has a medium drought tolerance.
