In a genus known for morphological and taxonomic challenges, the vibrant floral bracts of Castilleja have long fascinated botanists. Despite the group's high diversity in the western U.S., Castilleja coccinea, the scarlet paintbrush, is one of the few eastern species and displays striking flower color polymorphism. While scarlet is predominant, a yellow morph appears in some populations, primarily in the Midwest region. In “Selection maintains floral color polymorphism in the scarlet paintbrush Castilleja coccinea (Orobanchaceae)” in this Special Issue (“Paradigm Shifts in Flower Color”), Fetterly et al. explore abiotic and biotic factors shaping this polymorphism. They identify habitat differences as potential drivers of color divergence, while floral trait variation suggests pollinators and environment act together to maintain distinct morphs.

Please share! Our lab is recruiting a PhD student to join us starting fall 2026. Our group is broadly interested in plant molecular evolution and comparative genomics. More info about our lab and grad programs at Colorado St. is available on our lab website.

As a Harvard international graduate student… I’m sad. And scared. Really scared.

Harvard has just under 6,800 foreign students enrolled. Every one of them would have to give up their dreams of an education in the US or transfer elsewhere, if Noem's attack on Harvard is upheld.

None of them have done anything wrong, they're just collateral damage to Trump.

🌼The first episode of the BSA's new podcast---A Botanical Podcast!---is now available on all major streaming services!🌼

In this episode, Andrea Berardi explores the #evolution of flower color & why plants change their colors.

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...
Visual abstract: “we test hypotheses about floral diversity with community science data and an advanced computer vision model. Red/orange flowers have delayed flowering that matches hummingbird migratory patterns”

Going to do some hummingbird pollination observations this spring, and exploring having backup camera/photos to supplement in-person observations. Curious if anyone has successfully used camera traps/game cameras to capture hummers? Don't want to use regular video cameras if I can help it.

I am excited to share that I will be joining the Department of Biology at James Madison University as an assistant professor this fall! Looking forward to starting my lab, where we will study floral color evolution, Silene speciation, and plant pollinator interactions! #newPI
