Wouldn't you be grafting the late flowerers on to the ones that have grown in the desert, not the ones that have grown in the desert onto the late flowerers.
I have the same query as you, at least as far as the altitude is concerned and so the necessity for a late flowerer which are late flowerers
Apricots also seem to enjoy growing in my garden though they have not fruited, so do wild plums whose fruit is not widly exciting. I turned the apricots i grew on my balcony from apricot stones and some that rame up from the stones i threw into the flower bed into a hedge, so they can't really fruit and i have one as a tree but it has not fruited yet, maybe it needs another apricot to pollinate it. It seem fruit trees many of them dont self pollinate well and you need to get another apricot to pollinate the one you wanted to have.
I thought english apricots might be good for such a high mountain site with late frosts. The apricot is not really a tree for England the sun does not shine hot
enough for them there so english varieties of apricot must be pretty cold hardy. I dont believe they fruit in England unless you put them in a very protected spot.
In which week of the year fruit trees flower seems to be a question of type and they mention it when the nursery talks of the different types of tree and so you only have to go through their lists to find out which tree flowers when.
I am suspicouse of the trees i can buy here because they are the most known varieteies of that fruit or i fancy they are. When England joined the european community, then the type of
apple that could be sold got imposed on the English and many apples that you could buy before became hard to get, some of the old ones better than the sorts sold in the shops after we joined the common market, I ended up wanting to support the fruit that was not the most marketed, growmg the varieteis you can buy in the green grocers has little attraction for me compared to the idea of preserving the great variety we used to have of fruit trees. agri
