Lantana

I see it grow wild there, also. They all in full bloom here, also.

Yes , they are everywhere. I do like it though. Happy where ever they are. Sort of like Mexicans :-)

They can make it cheerful.

This Lantana is grown in the medians here...along with Natal Plums, Indian Hawthorn, Bird-of-paradise under the Jacaranda trees.

no bugenvilias?

Yes, Bougainvillea 'Rosenka' is pretty widely used in medians. The large varieties are widely used along the freeways.
