Gurcharan ji, beautiful flowers.  Are they fragrant?
Regards,
Mani.

Not unfortunately. Schizanthus is also commonly known as poor man's orchid.

I am confused whether to keep it as Schizanthus pinnatus Ruiz & Pav. or Schizanthus wisetonensis Hort.

If we go by BSI Flora of India Checklist and Floriculture in India - Page 104 (1986) (hybrid of S.pinnata and S. grahamii), only Schizanthus wisetonensis Hort. is listed. However, WFO says this as unchecked name, while POWO and CoL does list this. Making the Most of Shade: How to Plan, Plant, and Grow a … – Page 259 and Handbook of Flowering – Volume 6 – Page 569 state it to be a hybrid of S.pinnata and S. retusa/S. retusa 'Grahamii'.

On the other hand, Schizanthus pinnatus Ruiz & Pav. is listed in WFO, POWO as well as CoL.

Dear Garg ji,

   There is no species as Schizanthus wisetonensis - there is a hybrid by the name Schizanthus x wisetonensis. According to the Handbook of Flowering by Halevy, the species most often used as an ornamental plant is Schizanthus x wisetonensis. I am attaching the chapter from this book which discusses this plant.

   I think it will be safe to assume that the cultivated plants we are seeing are Schizanthus x wisetonensis.

   Best wishes

   Tabish
