Delphinium Delgenius Series (Pacific Plug & Liner)
Delgenius is a new series with three colors from hellebore and echibeckia breeder, Bart Noordhuis. This Delphinium takes a crop that has traditionally given growers a hard time with many problems and makes it easy. No more small plants. Delgenius fills large pots with only one liner and produces a multi-branching habit in a short amount of time. No more single blooms. Delgenius has multiple semi-double blooms and will rebloom if cut back. There is no need to use plant growth regulators either, as they are genetically compact. USDA Hardiness Zone: 3-9
Glitzy is the newest member of the Delgenius family, with deep-blue flowers and a white bee. Glitzy is a 2022 introduction.
