Last week I spotted a photo opportunity – the ever reliable and long flowering Ageratum “Blue Mink” boldly flowering amongst the autumn chaos. But who is this muscling in on the picture? And where might I ask did you come from? You certainly weren’t planted there so I can only assume (no need to call in Miss Marple on this occasion) that you are a seedling from the nearby Lobelia x speciosa. This behaviour certainly is to be encouraged. More self seeded lovelies please!
