Leptospermum polygalifolium - Tea Tree

Very pretty. Are the flowers fragrant?

Not as far as I know.

Attractive flowers.
Understandable that gardeners in your region are keen on drought tolerant plants ! :o)

Wow I would never have expected to see the tea tree growing over there - great specimen too!

There's many millions of these plant growing all over California. They grow throughout all low-elevations of California.
