My Garden is Confused

We are now into the middle of March and by now my Ornamental Grape Vine (?? Botanical name unknown ) is usually turning a bright red and starting to drop its leaves everywhere.
When I was washing up the breakfast dishes this morning I noticed that said tree had some tiny new green leaves starting to shoot.
No wonder it is confused we are now getting temperatures again up in the high 20's Celcius.
Last week I had to get out a pullover now we are back into shorts.

This little leaf almost appears to be asking "is it safe to pop out".

Ahh this crazy weather.
