Water Saving Tip:

Even during our hottest months we don't need to water daily.

Give your plants a chance to breathe.

Water late at night or in the early morning hours to avoid losses to wind and evaporation.

  • Description

  • Notes

This beautiful perennial reaches 2'-4' tall and 3' wide. It spreads by underground colonies so it's a good plant for difficult slopes. Thick upright stems have large, hairy, gray leaves. Fragrant pink and white, star shaped clusters of flowers bloom in spring and summer. This plant does well in poor, dry, well draining soil in full sun. Monarch butterflies lay their eggs on the leaves and stems so don't spray plants with chemicals. Is winter dormant.
Frost tolerant to 20 F. Also try Asclepias linaria.
