Research group investigating physiology, ecology, evolutionary biology and conservation of genus Rhododendron. Sharing research, gardens, plant exploration, art, culture, events, anything and everything Rhododendron
Identifying observations for others is one of the most impactful things you can do on iNaturalist — and you don't need to be an expert to start.
Join us on March 19th (Taxonomy Day!) at 9am PT for a free webinar on how to help your fellow iNat community members: tr.ee/7Opp8zGkIQ
One of my first plant friends 🥰🤩
Well hello Rhododendron minus
HOT PINK form!
This specimen is from
Sawnee Mountain in Northern Georgia
Interesting that the white forms seemed to emerge first and later flowers were more pink, this is the last location to bloom and it is definitely THE MOST pink
Que guay nice work Burquenos
YES! rhododendron are members of family ericaceae!
Ooooh 🤩
high relevance for rhododendron!
New research reveals that the Rhododendron pseudochrysanthum var. taitunense is a distinct subspecies, uniquely characterised by its glabrous leaves, larger seeds and specialised pollen morphology.

I wait for cherry blossoms
scattered on wet pavement
for fat gold rhododendron buds
new pine-bough tips
bright as candleflame.
Meanwhile in the clovered grasses
rain meets earth,
quiet as murmured love.
Rain & rain & rain—
soon softer skies & flowers.
Always you.

Yay! It’s Rhododendron”s yummy cousin, blueberry! such cute tiny flowers!
Colors are one of my favorite things about plants (and life in general lol) so I was excited to see how small a difference I could see between colors
What's My JND? 0.0032
Is that good?

Nice! Are you at Philmont Ranch?

A fun talk on Rhododendron minus pigments
how they protect plants from stressful conditions
how they vary across the species range
and some ideas on why we have a preponderance of cold hardy purple flowers, while yellows and reds are more common in tropical species
Rhododendron sure has some
Complex Species Complexes!
(Aka, Taxonomic uncertainty)
Analysis of Rhododendron pseudochrysanthum species complex shows
R. pseudochrysanthum ssp. morii Yamazaki is distinct from R. morii Hayata, as well as R. pseudochrysanthum Hayata, and R. hyperythrum Hayata!

Florida's pink pinxter (Rhododendron canescens) azalea is displaying pink flowers with the plant's green leaves visible against a backdrop of leaf litter and a pine tree trunk at the upper left
Pink pinxter azaleas are in bloom this week. #nativeplants #nature #bloomscrolling #ECK #wildflowers #Florida #spring
White azalea with light green flare, a hybrid I believe
Violet rhododendron with dark red flare, big round trusses, maybe Nova Zembla?
When grief becomes too heavy
An angry world
where hearts are broken
I recall you in your garden
I bring your spirit out to play
If only for a moment
May we feel your joyful presence
here with us, again, today

Fire red orange azaleas with large flowers about 5 inches across and dark orange flare, is it a hybrid? calendulaceum, or canescens? Your guess?
Pink azalea with hot pink centers, flowers about 3 inches across and star shaped, maybe R periclymenoides?
Yellow azalea with pale green flare. A ball truss with about 6 flowers each about 4 inches across, I think a hybrid
White azalea with large pink stamens like hooked beaks, R arborescens?
Winter’s grip is breaking
Bulbs are slowly waking
Next up will be amazing

Pink rhododendron blooms
The rhododendrons are getting ready to bloom in the Seattle area. The flower between mid-March & mid-May. So, they should appear in time for St. Patrick's Day. Knowing parks & neighborhoods are about to explode with color warms my heart. Despite the cold, snow, & slush around us, spring will come.
Not from Ventura, I grew up on a different part of the “Mexican Foods of the World Map”, but I always very much enjoy to see the many different local variations on the theme, first time hearing about Corn Burrito, and it looks yummy 😋
Potted rhododendron in a greenhouse covered top to bottom in orange flowers, the greenhouse light is altering the flower color, in real life the look more brick red-orange
Close up of the Rhododendron kiusianum flowers, this picture is more color accurate showing their brick red petals and magenta flare
Rhododendron kiusianum doing its best to impress an audience of one in the greenhouse today
#bloomscrolling
Rhododendron make great lifelong friends! Nibbling the flowers sounds fun and a bit exciting!
Significant resistance of alpine Rhododendron chrysanthum to UV-B damage includes biosynthesis of phenylalanine, tyrosine, & tryptophan & accumulating L-phenylalanine and L-tyrosine, transcrption factors exhibit both synergistic & antagonistic regulatory roles in amino acid metabolic pathways

Taking a lot of great quality photos like you have is excellent of course, then probably think about dried pressed and maybe frozen samples if it came to that, fresh flower buds are used for genetics analysis of Rhododendron
The story of the provenance is actually what intrigues me about it, there are many such stories we run across in rhododendron, especially vireya, and some of them are true! There is a nonzero possibility that it is a lost or undescribed species is too important to pass by
Great! 👏🏼👏🏼👏🏼
I think Yasper will first be looking to see if it matches the descriptions of described species which haven’t been seen for a long time, there are about 100 at least that were described 1800-1900s and now essentially lost to science. I will DM once I get info from him
If you would be willing to share samples a student in our lab from Papua who also knows the Vireya flora of Papua New Guinea very well is doing a taxonomic revision for their PhD and would have the skills to be able to try and answer this
I know someone who can tell us the answer to this mystery, hold my beer, I’ll be right back
This is egregious scientific misconduct and the entire journal should definitely be de-indexed and removed from all reputable search engines
Frankly this saddens me, peer reviewed and trustworthy science is one of the most important pillars of society, pretty sure this is how the dark ages started
