Taking a walk around the streets, usually in my lunch hour, there are 3 plants that seem to be attracting the bees the most. Salvias, Eucalypts and another plant (shrub) that I havn't found the name of yet. It has slightly rusty small pointy leaves with small white trumpet to bell shaped flowers. It is common in the gardens from the sixties and seems to be making a comeback again in some of the newer gardens too. With the Eucalypts they seem to have just started opening in the last 24 hours.
Feel free to add to the list.
Phil, google Abelia spp
and see if that is the one you're thinking of
