I don't see many or even any apples so far, but there are plums. In French, they're prunes. And the ones pictured here will become small, ping-pong ball size fruits.
The red ones are red now, and they've been red from the beginning. The tree itself, which I grew from a pit and then planted in the back corner of the yard, has leaves with a dark red cast to them.
The pit came from one of the plums in the neighbors' yard across the road. Those plums begin their life green, and stay green for quite a while before they turn red and ripen. At this stage, they look like olives. The one I saved the pit from, several years ago, had turned ripe and red, of course.
The plums that are green when immature grow on a tree that has green leaves. The tree is less striking to the eye, in other words. Less decorative. Each tree and each fruit has its advantages and disadvantages.
The main difference between the two types of plums is that the ones that begin green, and turn red later, are "freestone" fruits. In other words, the pits are easy to remove because the flesh of the plum isn't stuck to them. The ones that are "born" red and stay red are a lot more trouble to work with, but they taste good.
