Rose Verbena
Glandularia canadensis
In the United States:
Native
· also called rose verbena, rose vervain
Honeybees forage on Rose Verbena for nectar and pollen during its main summer bloom, peaking in June-July to support colony needs in mid-season. This low-growing perennial forms mats in sunny, dry sites and self-seeds prolifically, potentially requiring occasional thinning to prevent overcrowding. It tolerates drought but may act as an annual in colder northern zones.
