Question from
Paul Benson
I have been growing this alpine for the first time this year. It's planted in a container using John Innes 2. It produced a flush of beautiful blue gentian coloured flowers. These are now finishing and the leaves which were a healthy looking green are turning black and dying. There are some new green shoots arising in a few places including some new flower buds, so I know the plant is still alive. But should the old leaves that came with the first flush have died so quickly or is that normal for this plant?
