Many years ago when I grew Silene hookeri it was a pale salmon pink colour. It was usually short lived but I did have one which lasted a few years. It seemed to disappear from the seed lists for a long time. I did get seed from the SRGC seed list in 2012. I have 2 survivors. They are much loved by slugs, aphids and red spider mites. They are fairly straggly plants with bright magenta pink flowers. I had long admired the beautiful white Silene hooker ssp. bolanderi shown by Cyril Lafong and was delighted when he gave me small seedling along with a seedling of a compact form of the magenta Silene hookeri. I managed to kill both but did get seed of the magenta one. I have a few seedlings which are beginning to flower now.
In October I also sowed seed from Alplains of Silene hookeri, Silene hookeri ssp bolanderi and Slene serpenticola.
