Phoenix reclinata - Senegal Date Palms

Is that a Schefflera in the right spot of the photo?

Pretty planting.
Do areas like this have sprinklers watering the grass etc ?

Terratoonie:

Virtually, everywhere there's green plants there must be a sprinkler-system...we don't receive enough rain to sustain many green plants.

Aleyna:

Yes, the fairly new name is Schefflera pueckleri -however, very widely known in California as Tupidanthus calyptratus - Mallet Flower.

What a beauty
