White wand beardtongue

White wand beardtongue should be watered at least once a week, giving the plant about 1-1.5 inches of water. It likes the ground to be kept moist but not soggy. During summer, the plant should be watered more often (every 4-5 days) due to increased evaporation. During winter, you can reduce the amount of water given and stretch the watering cycle to once in 10-14 days.

White wand beardtongue prefers full to partial sun, with at least 4 hours of direct sunlight each day. This plant species likes to be in an area with bright, indirect light and will thrive with some light shade during the hottest part of the day in the summer. Direct sun in the later afternoon is recommended, as this is when the foliage is able to cool off and thrive. This species may do best when in an area that receives the majority of its daily light in the first half of the day, allowing the leaves of the plant to dry quickly and the soil to remain relatively cool. The White wand beardtongue will receive the most sun during the spring and fall, with the sun reaching its peak intensity in the early morning and late evening hours.

White wand beardtongue (Penstemon tuba-florus) should be pruned in early spring when the plant is still dormant. Pruning back the plant to 6-8 inches is recommended. This will help to stimulate healthy new growth and ensure that the growth does not get too large and out of hand. Pruning should be done sparingly as it can limit flowering and cause damage to the plant. After pruning, some light fertilization may be required to help the plant reach its full potential.
