Blue Buccaneers Delphiniums are impossible to miss—they're big, they're bold, and they're BLUE. These striking flowers are New Millennium hybrid delphiniums, bred in New Zealand for their notable height, unbeatable performance, and strong stems. Blue Buccaneers grow up to four and a half feet tall, with stunning, electric blue flower spikes that butterflies love. While classic delphiniums decline after two to three years, New Millennium hybrids return for several seasons. Although these delphiniums will need staking due to their towering height, their stems are strong and won't wilt. Plant in full sun with good support. Delphinium 'Blue Buccaneers'
