Blue Vervain

Verbena hastata

Plant Details:

Plant Type: Perennial
Plant Family: Verbenaceae
Plant Description: Rough, sharply toothed foliage grows in irregular clumps. Attractive flower spikes sit high above the foliage on hairy, extremely slender candelabra-like branching stems. The spikes are made of tiny, densely packed, purple-blue flowers and are enjoyed for most of summer and may even last into early fall. Blue Vervain prefers wet soil (although it can handle moderate dryness) making it perfect for rain gardens, bioswales and along waterways.

Maintenance:

Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
