rose vervain

Rose vervain (Glandularia canadensis 'Shauna Ann') should be watered once or twice a week depending on your regional climate and the season. During the winter, water less often as the plant enters a period of dormancy. During the growing season (spring through summer), water the plant deeply but not so much that the plant becomes waterlogged. The soil should be allowed to dry out in between waterings. Water the plant at the base of the stem, avoiding the foliage which may get damaged by water droplets.

Rose vervain (Glandularia canadensis 'Shauna Ann') prefers full sun to part shade for best results. It can tolerate light shade but too much shade can cause the plant to become lanky and stunt its growth. Plant it in an area that receives full sun in the morning and part shade in the afternoon for optimal growth. It's important to provide at least 6 to 8 hours of direct sunlight each day during the growing season for Rose vervain to bloom properly. During times of high heat, provide light afternoon shade to prevent stress.

Rose vervain (Glandularia canadensis 'Shauna Ann') should be pruned annually in late winter before the new growth emerges in late spring. Pruning should consist of removal of dead, damaged, or weaker stems and cutting back plants to a height of 8-12 inches. It is important to keep the center of the plant open to allow for air circulation and prevent disease. Hand pruners, loppers, and hedge shears can be used for Rose vervain pruning. During the growing season, remove any damaged or faded flowers and light tip pruning can be done to promote bushier growth.
