Growing Tips
Plant in a well-drained soil that has been slightly enriched with organic matter.  Too much organic matter tends to make
short lived penstemons that require staking.  Loving a pH range of 6.0-7.0 and full sun location, penstemons are easy to
cultivate plants that attract hummingbirds and butterflies in masses.
