Yellow flowers clustered into small round heads on a long racemes. Very showy and one of the reasons the trees were so very popular in the day. Bloom very early, many years late January or early February, slightly later than A. dealbata.
Trunks are smooth, gray color. Nothing to write home about.
447 9th Ave SC
Misidentification: Most likely A. dealbata, which looks similar, blooms about the same time with the same looking yellow flowers. However, the foliage of A. dealbata is much larger, the lateral leaflets longer. And the tree is taller, and maybe more likely to fall down.
The purple one seen above it located on the corner of Soquel Dr and Crystal Heights,
2422 Mission St in the parking lot at the Sunset Inn (Purpurea again)
