Lantana ‘Dennholm White’;

Seen in the garden during my visit in October, 2018.

A cultivated, dwarf, garden plant

Some cultivar like Lantana ‘New Gold’

For me also it looks like Lantana cultivated New Gold.

In your photos the blooms are not yet fully opened. It might be Lantana Dwarf Dennholm White. Lantana are very good plant for butterflies and bees.

Thanks a lot … Yes, these were dwarf, trailing plants.
