Superbena Imperial Blue verbena's deep blue-purple flowers are clustered in large umbels that cover its deep green foliage. Like all verbena in the series it is vigorous and mildew resistant. Great for containers where it plays the role of 'spiller' but also a standout in the landscape, where it is best planted at the front of the bed due to its low habit. It will grow and bloom without needing to deadhead. You and the butterflies will enjoy its beauty from planting to frost. Resists deer.

Deer resistant.
Try planting 'Wizard of Ahhs' Veronica hybrid in combination containers or near the front of the border where its prolific thick spikes of deep violet blue flowers can make an impact.
