I bought this hardy perennial Lobelia plant as another candidate for around the pond. Brightly coloured spikes of scarlet flowers appear in late summer from deep purple foliage. This vibrant colour appears in the garden just as many perennials are fading. Divide large clumps every second year in spring. Protect the crown of the plant during winter with a thick, dry mulch. This moisture loving plant can also be grown at the edges of a pond if potted up it into a basket with aquatic compost. Harmful if eaten.
This plant was becoming pot bound so I have planted it into the border beside the Red Rose and think maybe I can divide it next spring and put some by the pond.
