Tanya and Jos, no guest, lots of feelings. Tanya is healing her plants and starting to prep for Corsica. Jos is moving an entire anthurium collection out of a greenhouse he lost on two and a half months’ notice.
Plant drama: an Indonesian Anthurium ‘Muchlis’ sold in the US for $3,000, and the post that followed. Tanya talked with Aina, an Indonesian-born chef in the San Francisco Bay Area, about giving credit, “good” gatekeeping, and why “Indo” should never have meant knockoff. Jos tells the story behind the name ‘HU’.

Brian Lagunas, aka Anthurium Papa, joins Tanya and Jos for an episode full of heart and a little chaos.
News: The Crop Trust’s report on edible aroids and why collectors might be part of the backup plan; Costa Rica paying landowners to keep forests standing, and measuring recovery by sound; and the Desert Botanical Garden’s rescue center for confiscated plants.
Interview: Brian’s path from a fateful Anthurium warocqueanum encounter at Ecuagenera to breeding within a year, his friendship with legendary grower Barry Schwarz, meeting Dr. Tom Croat at our Miami barbecue, why water quality is “crucial,” and how he set out to kick down the gates of a gatekept hobby.
Hot take: Should breeders give a whole seed batch one name? Brian says no. Jos disagrees, mostly.
Hot or Nah: A Hoya with fuzzy black new leaves, an inappropriately shaped Abelmoschus, and the $40,000 Monstera everyone side-eyed in Miami.
Rate That Weird Plant: Brunsvigia orientalis, Utricularia dunlopii, and Paronychia erecta.

Tanya and Jos are home from Miami, cold, jet-lagged, and still on speaking terms. This week they spill the tea on their first-ever IAS Tropical Plant Expo.
In the news:
Hold My Bud: oaks that got eaten by caterpillars one year open their buds about three days later the next. That's enough to starve the hatchlings, and enough to cancel out a decade of climate-driven early spring. Published in Nature Ecology & Evolution.
Pilea does math: the vein loops on a Pilea peperomioides leaf form a near-perfect Voronoi diagram around its hydathodes. This could change how botanists think leaf veins form.
Who grew your houseplant? Grist reports on the WeCount! campaign asking Costa Farms and big retailers to sign a worker-written code of conduct on heat safety. Ethical sourcing shouldn't stop at the forest edge.
Miami:
Two visits to Bill Rotolante's Silver Krome Gardens

Booth lessons from a bootstrapped European startup
Jos's talk on intersectional hybridization in Anthurium

Episode 20 and we finally have an aroid taxonomist in the room. Marco Cedeño Fonseca is a Costa Rican botanist who did his master's on Monstera at the University of Costa Rica and just finished his PhD at the Berlin Botanical Garden — as in, he got the title the day before we recorded and told us at the very end.
News: the Thomas B. Croat Aroid Garden was inaugurated in Tabasco, Mexico. A 5-meter plant gets a strong opinion out of Marco about plastic plants in Costa Rica. And a new Typhonium was named in Thailand, which sends us down a hole about why genera keep getting split.
Interview: How a forestry student ended up building a greenhouse in his apartment to germinate Monstera seeds; why juveniles are the taxonomic problem; the Monstera everyone calls esqueleto that has never been documented in the wild; what a Costa Rican field botanist does all day in a German DNA lab; and the one Monstera he's never seen.
Hot or Nah: Dendrobium Kirkland Nixon 'Bredren', Anthurium warocqueanum × veitchii, Dionaea muscipula 'Medusa'.Rate That Weird Plant: Gethyllis namaquensis, Tecticornia verrucosa, Ranunculus semiverticillatus.

Your plant isn't being dramatic when it stretches for the window — it's reading the light. This week Tanya and Jos get into a red-shade-cloth vanilla farm in Hawaii, the real science of phytochrome and shade avoidance, and why cannabis growers manipulate far-red light on purpose. Plus: an AI plant-photo fraud scandal shakes the collector community, a Hawaiian botanist free-solos volcanic cliffs to save endangered plants by hand, two Australian orchids get pulled back from the brink, and Tanya drops a hot take on who actually gets to have an opinion about non-native gardening.
In this episode:
News — An AI-generated plant photo scandal rocks the collector community; field botanist Steve Perlman free-solos 3,000-ft Hawaiian sea cliffs to rescue endangered native plants; two Australian orchids (the Queen of Sheba orchid and the Rosella spider orchid) get major conservation wins; and a humbling lesson on humidity, monsoons, and what "houseplant" even means depending on where you live.
Main Topic: Red Light, Explained — What a lava-red vanilla farm in Hilo taught us about phytochrome, shade avoidance, and why your leggy pothos is just speaking a language plants have used for millions of years — plus how cannabis growers weaponize far-red light for bigger yields and higher THC.
Hot Take — Should Europeans stop planting palm trees? Tanya says the people criticizing them should look at their own backyard first.
Hot or Nah — Cymbidium goeringii 'Cheonjong', Philodendron 'Jupiter', and Alternanthera ficoidea (Joseph's coat) go under the microscope.
Weird Plants — A starfish-shaped Mexican vine (Dictyanthus pavonii), a South African micro-succulent with a flower 20x its own size (Oxalis bullulata), and a spiky Amaryllis relative found in a 64-square-kilometer sliver of the Western Cape (Brunsvigia radula).
