Lobelia cardinalis
cardinal flower
This impressive perennial produces showy red flowers that really stand out from the crowd. They form in tall spires, which if cut back after the flowers have faded, will usually go on to form lateral shoots that will carry even more flowers later in the season. This usually ensures that there is a continuous display of flowers from early summer to mid-autumn. An exotic-looking plant that looks great at the edge of a pond or forming generous drifts in a bog garden.
How to care for Lobelia cardinalis:
Plant potted Lobelia cardinalis in moist, humus-rich soil in full sun or partial shade, keeping the soil consistently damp, offering protection against slugs and snails.
Once established, divide large clumps of plants every second year in spring. Protect the crown of the plant during winter with a thick, dry mulch, such as straw if above the waterline.
This moisture-loving plant can also be grown at the edges of a pond, and will tolerate water levels up to 7cm (3in) but best purchased in aquatic pots (or potted up with aquatic soil). Please see our aquatic pot range here.
