More blossoming trees - what do we need to bloom?

I have had a very reflective weekend (in addition to getting some quality-length naps).  On Thursday, on the way to work, I found a new crop of flowering trees - crab apples, I guess, with a rich, deep color and very sweet smell.  They must have just popped out in bloom.

Lilacs are starting up too - it's been slow and easy in the past couple of cooler, rainy days.

None of this has happened before in April here in the north-lands, in my recollection.  But even though it raises fears of global warming, this mild month of early, slow, exquisite spring has been a blessing.  Previous springs have seemed to flash by in a week's time.

Now - what will it take for us to bloom?  For me to bloom?
