Wow 1001 that’s cool! Congratulations 🎉 And 10 Rhododendrons!

This one flower bud on my Rhododendron atlanticum is… 🚨EXTRA FANCY🚨 It’s on a very tall branch that I often see on azaleas, I call them the “Superman arm” cuz they kind of punch up 😹 Anybody have a guess “why”? This bud is so different? my guess - Superman arm has apical dominance hormones

Very interesting article for Rhododendron!

Well planted Rhododendron do indeed thrive on neglect But they do demand to be admired everyday!

Feel that rain? Come get some plants at Nobody Nursery today and tomorrow, 10-6 I just got back from a three day seed collecting trip on the east side of the north Cascades, and the only photo I thought to take was of this Rhododendron neoglandulosum (mountain Labrador-tea). Available next year?

There are over 10,000 named varieties of azaleas, with many more hybrids and species existing, although the number in active trade is much smaller. All azaleas belong to the genus Rhododendron. Azalea Society of America 🌱🌿👨‍🌾🌻 #TheOutpost Learn about azaleas share.google/Ybksm2N6fkfN...

Rhododendron varieties are approximately 1,000 species with a vast number of hybrid cultivars like 'P.J.M.', 'Nova Zembla', and 'Roseum Elegans', which offer diverse flower colors, leaf shapes, and bloom times. #TheOutpost 🌻🌱🌿👨‍🌾 21 Different Types of Rhododendron share.google/VuWLSkXPl4Jh...

Delightful autumn blooms!

I found this birding book along the side of the road on the Tamiami trail in the Everglades on 8/25/25. It is so well loved with sightings going back decades. If you're a birder (I am not) please spread the word and hep me find the owner so they can be reunited

Genetic diversity was assessed for Rhododendron arboreum, a keystone tree species in the Himalaya facing threats from habitat-loss, limited regeneration, overexploitation, and climate-change. They examined populations at nine different altitudes, finding interesting patterns of heterozygosity 🧪🍁🌿🌎🌐

A very interesting study about the factors shaping plant communities in Greenland, includes data on two Rhododendron species (formerly Ledum), Rhododendron groenlandicum and Rhododendron palustre 🧪🌎🌿🍁

Lots of rhododendron on Sumatra, feeling this record breaking heat wave!

Fantastic Fall color is, IMHO, one of the most under appreciated aspects of Rhododendron! With fall colors that are just as pretty as their blooms, showing off on the greenhouse today is Rhododendron pilosum AKA Minibush Native to Northeast US, including Pennsylvania and Ohio #bloomscrolling

Oh Hai! I made Mr and Mrs Bacon and their little baby Eggbert

growth and regulatory mechanisms of Rhododendron moulmainense to high-temperature stress shows interconnected pathways of starch-sucrose metabolism and ABC transporters and may help us better understand the domestication processes of Rhododendron 🧪🌎🍁🌱

Chornohora is the highest mountain range in the Ukrainian Carpathians located on the border of Zakarpattia and Ivano-Frankivsk regions. It is especially beautiful at a time when the slopes of the range are covered by flowering rhododendron. Photo by: Alexander Kotenko. #StandWithUkranie

Have you ever seen the rhododendron bud blast fungus Seifertia azaleae? As the name suggests this fungus is a pathogen of rhododendrons and azaleas! #Mushrooms

Years after years, I still enjoy my field trips to the mountain forests of Yunnan. Yesterday, we were selecting sites in the fir–rhododendron woodlands of Jiaozi Snow Mountain, surrounded by the lush flora thriving after the monsoon rains.

Rhododendron "President Roosevelt" is a cultivar of Rhododendron with striking variegated leaves and trusses of bright red flowers that fade to white in the centre.... It is named after the 26th president of the United States, Theodore Roosevelt.... Here seen in Hou (Denmark)....

Yet another report showing Rhododendron secondary compounds effective against infectious diseases this time it’s H1N1 induced pneumonia The pace of this research on Rhododendron is increasing & rightly so w/dozens of species identified as VERY promising #medicinal #plants thousands more to assess

This study found the Ericoid mycorrhizal fungal community was highly diverse among co-occurring Rhododendron hosts within the same community, especially at higher elevations. Rhododendron Host species identity played a “predominant role” in shaping the composition of the fungal community 🌿🍄

Study of clonal structure and reproductive performance of Rhododendron aureum, comparing populations with different snowmelt in the Taisetsu Mountains of northern Japan They conclude that heterogeneous ecological situations in the alpine ecosystem lead to habitat-specific seed production patterns

The Blyth’s Tragopan (Tragopan blythii) roams the Eastern Himalayas and forests of Northeast India, Myanmar, and Bhutan, where dense rhododendron groves hide its secretive life.

Fun day doing thermal imaging of Rhododendron minus leaves Leaf temperature data extracted from these photos will be used to understand drought responses of R minus plants, and how that might differ for plants from Alabama, Georgia and North Carolina

This article contains some really excellent Rhododendron musings, the genus has very interesting patterns of biomass allocation

Great day for rhododendron at Holden Forests & Gardens SEARCH Symposium Six, count ‘em, Six undergraduate & high school intern Rhododendron posters! 🧵 1/6 First up, Congrats to Alex Speyer on their poster “preliminary test of soil, moisture, and atmosphere humidity on an evergreen azalea hybrid”🧪🌿

A stellar lab group this year, I’m tired and I need a nap because everyone was SOOO GOOD it was hard keeping up with y’all!! BIG Thanks to the 3 senior students for being a great mentorship support system, with your help we got a lot of work done & made it a great summer for the new folks, go team!

Remember kids, don’t eat Rhododendron! There are exceptions, but it’s easy to make mistakes Report of a 58-year-old man who presented with dizziness, headache, nausea and vomiting following the ingestion of four fresh white Rhododendron flowers during a high-altitude visit to Kalinchowk, Nepal

Blooming now in the greenhouse Rhododendron oldhamii This evergreen azalea species has both spring and late summer blooms, nice bright red flowers with a hot pink flare give a little spice to the garden and with very fuzzy leaves, it seems to be fairly resistant to lacebugs Native to Taiwan

Is there an associated paper to read? There are a number of native Ericaceae shrubs (like Rhododendron albiflorum) that are extremely challenging to cultivate, and I'm grasping at straws.

Oooh I’m sure my Rhododendron will be interested to hear about this research on one of its sworn enemies Botrytis!

While R ponticum is certainly problematic in the UK, vast majority of Rhododendron are not invasive, out of 1200 species and thousands of hybrids, only two have proven to be invasive, despite being given plenty of chances to become bad actors in gardens all over the world

Washington State’s flower is the Rhododendron. “In 1892, before they had the right to vote, Washington women selected the coast rhododendron as the state flower. They wanted an official flower to enter in a floral exhibit at the 1893 World's Fair in Chicago”

This study identified secondary metabolites genes using co-expression network analysis to elucidate the interactions, finding 200 transcription factors belonging to 36 families putatively involved in regulating metabolic pathways of R. anthopogon in response to changing altitudes 🧪🌐🌿🌏🍁 #PlantScience

This study uncovered four lineages and revealed nearly stable genetic admixture and hybrid origin of two lineages & suggest that hybridisation between the two early diverged lineages likely gave rise to a third, potentially facilitating a shift in habitat preference from rocky substrates to trees!
