The Starship Blue Cardinal Flower features tall incredibly erect spikes of deep violet blue flowers from mid summer through early fall. Starship Blue has a better rebloom than on any other blue variety we've grown over the years. The hummingbirds and butterflies won't have any trouble finding the flowers and will thank you for planting this one. A wonderful, easy to grow native that prefers moisture retentive soil and full sun to part shade. Plant it near patios, garden ponds and other outdoor sitting or living spaces where the brilliant flowers and hummingbirds feeding can be enjoyed from close up. Get all the details below!
