I have spent a lot of time studying the differences between nubicola and glutinosa.  they seem to be very closely related and I think are often misnamed in nurseries.   Nubicola comes from India and surrounds.   Glutinosa comes from Europe and surrounds.  They look and grow fairly similarly and I think glutinosa has circulated the most.  The name nubicola relates to the clouds and reflects the high elevation where it is found.

Both are winter dormant, and grow around a metre high with lemon/yellow flowers in summer and arrow shaped leaves.

They are tough plants and can be used in part shade.

Propagation is most likely by seed.
