The render is unrealistic in regard to the maturity of the landscaping in 2016. There's no way the trees would be that mature in two years time, when they haven't even been planted. It might look like this in 2030.
The apricots will be great some day. I hope they plant some Blenheims.
That's purely a matter of economics: you can locate and select "specimen" trees that are fully mature at a lot more advanced stage than saplings. It's just a matter of what you want to spend. Another approach is the trees have all been purchased as less mature, and so less expensive younger trees and planted and are growing now in a nursery setting, being readied for transplanting when the site is ready. That's how they did the trees on the World Trade Center site. Between modern cranes and helicopter lift capabilities there are really few practical limits on what can be placed onsite.
Go out, buy up an orchard that's about to go under the development bulldozer and there ya go: instant mature orchard!
