66061: Wow! Last week's weather was below freezing. It got down to 18 degrees. 4/12 and 4/13 is was 82 degrees. That brought on the blooms.
Redbud, ornamental cherries, peaches, Bradford pears (not a nectar/pollen source), dandelions, henbit, dead nettle, tulip trees, forsythia (no value to honey bees), crabapples, and native currants. There is a tree blooming all over town and for the life of me, I can't remember what it is.
