Other pollinators such as hummingbirds and butterflies will come and feast as well. Due to the height of this perennials it’s large enough to compete against many kinds of weeds and puts on a very pretty show when blooming. Blooms can last up to 4 weeks.

Penstemon Family: There are over 250 Penstemon species, mostly native to our western states and Mexico. Their flowers range from blue to white to red, with several bi-colors. The common name, Bearded Tongue may surprise wildflower gardeners, since many of the wild Penstemons are called Beard Tongue.

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
