The unidentified flower which tormented so many for so long torments no more. Ann drilled down to the exact species, with help from Achrachno, with Adrian and F hot on her heels. And here it is, the Mount Hood Pussypaws, Cistanthe umbellata.
That is indubitably it. Excellent job, my botanical detectives! I’ll be keeping a special eye out for specimens this summer: it’s become our flower, and your triumph.
The question now becomes, do I show you a kindness and only post stuff I’ve (roughly) identified? Or was this exercise in botanical mystery solving something you care to repeat again in the future?
