The gross form of the inflorescence again looks similar to that of
Acacia, but the foliage is wrong for this.

I interpret the plant to have capitate clusters of flowers borne at
intervals along leafless flowering branches. I am assuming that the
foliage belongs to the same plant.

My first impression was Acacia, some species of which are cultivated in
fairly temperate regions:

However this would require the foliage to be from a separate plant or the
painter to be unfaithful, neither of which can be precluded
