Growth Habits and Garden Considerations
Beyond its height, Verbena hastata exhibits certain growth habits that are beneficial for gardeners:
- Self-Seeding: This plant may readily self-seed in garden environments where conditions are favorable, allowing it to naturalize and spread over time. This can be advantageous for creating a wild garden aesthetic or filling in larger spaces.
- Ideal Placement: Given its height, American Blue Vervain is best planted where it won't overshadow smaller plants. It works well in:
- Pollinator gardens
- Rain gardens
- Native plant landscapes
- The middle or back of a perennial border
Understanding its potential height and width helps in proper placement and garden design, ensuring it has adequate space to thrive without becoming overcrowded.
