I already have 2 Carmine/Tillamook plants in their second leaf. Scroll up in the thread and you will see the purchase history and pictures.
I was looking to add (and alerting others of the availability of) the ‘Raintree Select’ Cultivar as it was available for pre-order. I added it to my cart but last night was my daughter’s 8th birthday and so we had a bunch of plans so when we were finally back home and done, I crashed without completing my order.
I don’t graft and I don’t plan to get started anytime soon. Maybe one day. I’ve toyed with the idea of trying grafting on Goumi, since I have two grown plants, and it may be the only way to get ‘Pippi’ for now (I’m on the waitlist for a plant from @JohannsGarden) but while others told me they were successful in grafting, I saw no indication it was easy for someone who might struggle with it like myself.
‘Raintree Select’ Is sold exclusively by Raintree Nursery as a potted or bare rooted plant. No scion wood is available that I know of. I’m not sure if it is patented.
I have two Carmine/Tilamook already and no interest in Red Gem or Sweet Scarlet. As is documented here and elsewhere, Sweet scarlet and Red Gem have much smaller fruit. Verified “large” fruited cultivars are just Pippi, Carmine/Tilamook, and Raintree Select. Looks Like in addition to @Cgardener, @CoreFlex was going to get Sunrise Ruby, so if they can confirm it is a larger fruited cultivar, I might add it to the collection another year. I don’t know of anyone else growing it.
