( / )

Please select all options.

The plant’s showy floral display and pleasant scent make it appropriate for where a larger, short-lived wildflower is desired. These large, evergreen lupines usually behave as a biennial: mostly vegetative the first year, with a few flowers, then display an impressive amount of blooms in the second year. The flowers provide pollen and nectar for bumblebees and other native pollinators and beneficial insects.
