Greengages.

Last year this tree had just TWO flowers, and NO fruit. I've never seen it like this before, just look at it.

Of course a late frost could still wipe out any future crop, but we would still have had this wonderful springtime spectacle.

I have to say, the greengage is not my favourite fruit. Firstly it seems to attract bugs, and secondly it becomes unbelievably SWEET when fully ripe. If one can find a bug-free, slightly under-ripe fruit, it's great.
