It is difficult to identify a plant without reproductive parts such as flowers and fruits.

It may be Strobilanthes sp. of family Acanthaceae.

Please at least provide some indications about origin. Is it cultivated?

Acanthaceaea or Lamiaceae ?

Is it fragrant?

My plant id app gave the result as Strobilanthus sp.

:-D

Dear Ariharan V N,

I think it is Hemigraphis alternata (= Hemigraphis colorata) of family Acanthaceae.

Thanks!

Fitonia sp, Acanthaceae familiy

As Dr. Arvind says - it is difficult to identify a plant without flowers and fruits, especially herbaceous plants.

But easy to identify your plant because it is ornamental, can find easily in Botanical gardens, first time in 2006 I seen this plant in Empress Garden, Pune.

Present accepted name is Hemigraphis alternata (Burm. f.) T. Anderson (basionym - Ruellia alternata Burm. f., type locality Java, Indonesia).

Also mentioned in Hortus Malabaricus 9: 115, t. 59. 1689.

In some floras mentioned as Hemigraphis colorata (Blume) Hallier f. (basionym - Ruellia colorata Blume, type locality Java, Indonesia), but this name is synonym of Hemigraphis alternata.
