Three trees

In Master Gardener Katie's yard are three very different trees: in front, the bare tree is a gingko, the red one is a liquidambar still holding onto its leaves, and the semi-bare one in the back is a valley oak. All three are deciduous but their timing is obviously different, as are their colors. The gingko turns yellow before the leaves fall, the liquidambar red through yellow and the valley oak just turns brown.
