Hi, Julie, Part of the challenge in locating Delphinum Connecticut Yankee may be your location. Seeds for it appear (on a Google search) to be available in the States. (It was selected as an “All-American Selection” in 1963, which means it’s high-quality and AAS plants are usually almost eternally available; FWIWhttps://all-americaselections.org/product/delphinium-connecticut-yankee/ and here’s a seed company description [there are others] https://www.redemptionseeds.com/delphinium-belladonna-connecticut-yankee-mix-seeds.html#:~:text=Delphinium%20belladonna%20Connecticut%20Yankee%20Mix%20is%20a%20celebrated%20All%20American,lavender%2C%20light%20rose%20and%20white.).
Coming up with a replacement is not easy—thinking color, height, double flower, and any other desirable features. But I Delphinium Double Stars https://gracefulgardens.com/delphinium-double-stars (this vendor appears to be in New York state). Another is Delphinium NEWMILLENNIUM but the page was only a plant description and the text reads “Selected in New Zealand … ” so it’s not clear where it’s available.
With that, I would only say try larkspur, which is a close relative. We hope this helps!
