Seen during my visit in October, 2018.

Unfortunately I have only one picture.
Flowers and leaves resemble Eranthemum Species.
Only the leaves are narrow.

Appears to be some Pseuderanthemum

Yes … But finding it difficult to pin down the species.

Thanks … Could be Pseuderanthemum ‘Purple Dazzler’ or Pseuderanthemum sinuatum?

I don’t think matches with any of these on net.
