Garden plant seen at the ABG in October.

Could be Lantana Species?

If this were a Lantana it would have toothed margins.

Thanks for a quick response. Lets wait for more comments.

Look some Buddleja sp. Once compare with Buddleja alternifolia

For reference :

Buddleja alternifolia has alternate leaves; the plant in the images has opposite leaves. 

Thanks for the suggested id and pointing out the differences.
Hope to get it identified.
