The new leaves on coffee plants can be one clue in identifying them. Along with the branch structure and leaf / fruit node spacing, there are hints at the plant variety. The problem is that varieties aren’t often very genetically distinct, and while Coffea arabica self pollinates, it still will naturally hybridize and mutate in the farm or forest. These are two hydroponic plants I grow: green tipped one is Ethiopian selection 74165 from Jimma coffee research. I collected that seed from a farm in Limmu 2 years ago. The “bronze tip” plant is the somewhat mysterious “Java” variety I collected from a farm in Sacatepequez Guatemala 3 years ago. #coffeeplant #coffeevarieties #coffeecultivars #wannabebotanist https://www.instagram.com/p/CIORefxBCWl/?igshid=qvqhw2oqme51

Baby coffee plants. I spent the morning replanting different varieties of coffee seeds I had collected. Given these plants picture are from Flores, Indonesia, the variety name “USDA” seems a bit odd. In fact they are a Ethiopia selection that the US department of agriculture sent to Java from their research facility In Maryland (!) to Jember coffee research in Java in 1956. The original collection site for USDA was Mizan Teferi in Bench Maji zone of western Ethiopia. So my little plants are global travelers! #coffeeplant #coffeevarieties #coffeecultivar #usda #indonesiancoffee #florescoffee https://www.instagram.com/p/B5dSiGwnQ4Z/?igshid=mloff7s2f18c

A lesson in coffee plant varieties would have to include the footnote that many coffees have spontaneously crossed over time, or regressed, or were never very stable to begin with. Today in Aceh we looked at a lot of cultivars on small farms. Even when a plant can be identified it’s not assured, as the identification is often guesswork and infused with local lore, or just wishful thinking. The Abyssinia varieties here in Aceh Sumatra are that, these odd elongated cherries stand out, but has some characteristics of Timor Hybrid too. Is it really descended from bold Typica brought by the Dutch, or has it been cultivated, selected, crossed, and mutated so much over time to be something quite different? I guess at the end of the day, it doesn’t matter so much to the farmer as long as it’s a healthy plant that produces well! This photo, Timtim Timor hybrid. Or Abyssinia 7.

Just for fun... all the popular coffee “improved Ethiopian varieties” from Jimma Area Coffee Reaearch. Let’s see how they grow on the California coast! 🤔 #coffeevarieties #ethiopiancoffee #growingcoffee https://www.instagram.com/p/BrinipdAjJ7/?utm_source=ig_tumblr_share&igshid=3u7v8swojbyd

This is Híbrido de Timor variety I collected on a trip to Timor Leste, that I then grew hydroponically. It’s been interesting to see the root development of coffee grown without soil. #justforfun #growingcoffee #coffeevarieties https://www.instagram.com/p/BqF4GZfgjty/?utm_source=ig_tumblr_share&igshid=1pk5cwwy5dsgc

“Super Gesha” plantlets from Nariño colombia. These were taken from trees that seemed to have superior aromatic and gesha character- even when tasting the coffee cherry and in the aroma of the blossoms! They seem very vigorous too. (Sadly I shared some seed with a farmer in Flores Indonesia and they didn’t grow 😢) #geshacoffee #coffeevarieties #growingcoffee https://www.instagram.com/p/BnCZLWDFhLI/?utm_source=ig_tumblr_share&igshid=3mwk0r68kxv8
