Accidental flower garden

A week ago, I noticed a reddish tinge on the branches of a "weed" tree in the ditch outside our back wall. I broke off two and put them in a vase, to see what they would do. Today, they rewarded me with these miniature spring flowers:

A very merry yellow.


The whole flower clump, pink base to waving stamens, is barely 1/2 inch long.


Same flowers, different lighting.

The previous photos were taken under my halogen desk lamp; for this one, I used a small LED flashlight, which gives a very blue light. It whitens the yellow, but shows off the pink tips of the six petals.

Buds and bugs at the tip of the branch.

I don't know what tree this is; I'll have to wait for the leaves to attempt an ID.
