Here in Santa Barbara, Ca, we have tremendous Cotoneasters. Beautiful fountain shaped large shrubs with bright orange berries. The old nomenclature was Pyracanthus. They grow exceptionally well under oaks, olives and on the side of the roads. Impossible to get rid of.
The common myth is that the more berries in the autumn the colder the winter...Ha! We've had dry hot crispy drought weather for 4 years! I'm sure the birds eat them, but not for the cold.
