Hot off the presses and so so thrilled. Thanks to @inaturalist.bsky.social + computer vision we found something beautifully simple: Red and orange flowers bloom later than all the other colors in the eastern United States. Paper here: authors.elsevier.com/a/1kwzh3QW8S...

I started getting reports of an unseasonal Joshua tree bloom in the last few weeks, and looking over records on @inaturalist.bsky.social it's pretty widespread! So we're putting out the call for folks to record this "bonus bloom" and help us study it 🌿
