These trees deliver some of the best apples we have ever tasted!   In fact... the Red Gemini won our 2021 in-house taste test.
This tree is hardy to Zone 2.    A more recently developed apple with a wonderful flavour. Similar to the Gemini but a deeper red colour. 
 
6-foot tree in 5-gallon pot.
 
Apple trees should be pruned for improved production and easier picking!
 
*Apple trees in rural areas need a cross-pollinator to produce fruit (most urban centres have enough neighbouring apples and even an ornamental apple nearby will suffice).  2 different types of apple trees are needed to achieve cross-pollination.
