Archontophoenix alexandrae? I have to keep mine soaked and in the shade or the fronds fry.

A.cunninghamiana. The original owner- the planter- told me he planted them from seed he sprouted around 1998,I think he said. He had more but new owners of the house removed another group. They and some other rare for the bay area palms.

There are a few cunninghamiana's around. They are a touch more cold hardy and that makes enough of a difference here that they survive some of our below average winters.

Some Kings in town survived 24f in 1990. Alexander palms on the other hand, that had been planted in a public garden in Oakland,usually a frost free climate, froze to death in that big freeze.

Best and most tropical looking palms in California!
