These beautiful indigenous flowers look their best in a pot, hanging basket or along the front of a bed. Plant a large group in the same colour together for the most impact. They’re also ideal for softening the edge of a pathway. Apart from deep blue lobelias, there are also light blue, purple, white, rose and crimson varieties. Most have a white eye in the centre of the flower.
Buy a six-pack of seedlings or sow seeds in autumn or spring in well-drained, preferably slightly sandy soil. They flower abundantly from October to March. Lobelias grow easily in all regions of the country as an annual summer plant. Keep well-watered during the growing season.
