The Ricks Red pictured is one of two types of a Ricks Red. It's the Daleys version. The original one from Rick Deering has black skinned fruit with vivid red pulp. The Daleys one has brown to red skin with lighter red pulp. The black skinned one is far superior. Got rid of my Daleys Ricks Red.
My Tamborine Lime? Weird name, considering Tamborine is an anglicisation of the local word for finger lime, or the being whose fingers the limes represent. So the Mt Tamborine Lime should be the finger lime. The other lime is the Dooja or Gympie Lime. It's basically looks like a Makrut fruit, on a finger lime tree. Foliage varies wildly, from tiny leaves to leaves 2/3 the size of regular lime trees. Is the mt Tamborine lime the same as the Dooja?
Not the Dooja, or at least markedly different from the the Dooja I am familiar with. Although I wouldn't say I'm an expert on them, I don't even grow a dooja, or even the desert lime anymore. I have 12 finger limes, and that's it for me. It might be a hybrid between a dooja and wild pink caviar finger lime. I'll try and dig up a picture. Aussie citrus was the seller and Mt Tamborine lime
is that seller's moniker. The fruit is round, green skinned with pink vesicles--the skin was not the burnished green/brown that I associate with Dooja. I have never seen a Dooja with pink pulp. But given how readily citrus hybridize it's not huge leap really. although the only finger limes I ever found in the wild had had either yellowish or clear pulp. Never found a true pink one. In any case, aussie citrus claims to be the man on these things, worth a chat with him probably. I had thought about buying ione when the listing came up, but the tree was 45$ before postage, which is too much for something that might have ended p on the compost heap.
I have three things called 'rick's red', one is the daleys one, one is the black skinned type you describe (the skin isn't really black, it's just insanely dark green that looks black) and another is a bright red skinned type that is slender and pointy, which someone else told me is 'scarab red'. Will the real Rick's Red please stand up?
