Can someone tell me if this plant is affected by daylength? I have grown this for 2 or 3 years and thought I understood it now. A pot with 12-18" high shoots was flowering well until very recently, when although there are still plenty of buds it has now stopped flowering. It is indoors on a west facing but shaded window-cill. Watering and feeding has been similar throughout. It increases well and several divisions were taken this year. Brian Whyer, Buckinghamshire, England, zone ~8
