dew flower

The dew flower prefers moderate levels of water, but cannot tolerate soggy soil. Water deeply once every week or 2, allowing the top 2 to 3 inches of soil to become dry before re-watering. In extremely hot weather, water the plant more frequently. Water in the morning or early evening to prevent evaporation and avoid water pooling on the leaves. If possible, water at the base of the plant rather than from overhead to reduce the risk of fungal infection and leaf scorch.

The dew flower (Penstemon cobaea var. purpureus) needs at least 4 to 6 hours of full sunlight each day for optimal blooming and growth. If possible, it should be kept in direct sun for most of the day, and should not be too shaded. It should not be planted in a location where it will get more than 8 hours of direct sunlight a day, as this could cause the plant to become dried out and stressed. In addition, the plant should be placed in a spot that is protected from strong, direct winds.

For pruning dew flower (Penstemon cobaea var. purpureus), it’s best to prune in early spring before the plant blooms. Pruning should be done judiciously, as too much pruning can remove the flower buds for the coming season. A light pruning of around 1-third of the previous season’s growth is enough to encourage new growth. Remove old dead stems, as well as any overly spindly or weak stems. Cut just above a leaf joint for the best results. After it blooms in summer, it can be lightly pruned again to keep it neat and tidy.
