This photograph is courtesy of John Harvey. I’d previously suggested John’s site as a photo resource link, including the section on Learning Photography. John participates from time to time on the UBC Botanical Garden Forums, where he submitted this (and other) photos via the BPotD Submissions Forum. Thanks John!
I don’t think I can add much to what Richard Hebda of the Royal BC Museum has written about showy Jacob’s-ladder, so I suggest visiting that web page to learn more. Since the species occurs in Washington state, the ever-reliable Burke Museum of Natural History and Culture has a section on Polemonium pulcherrimum with a variety of photographs.
