Talkback: Plants on railway embankments
More recently I went on a longer train journey and was interested to see how the buddleia colours vary. I had always assumed that the bog standard "railway" buddleia was a mauve colour, but along this journey I noticed various shades of deep blue/purple, deep red/purple, and through to the pale mauve that I had expected. One plant had the most magnificent panicles of flowers, easily 18 inches long each, and worthy of a place in any buddleia competition. I assume all these are escapees from cultivated varieties in peoples' gardens, but with the cross breeding going on between them there must be some amazing plants waiting to be discovered.
