Description
Lobelia cardinalis, commonly known as Cardinal Flower, is a striking marginal pond plant known for its vivid red flower spikes that stand tall above fresh green foliage. Flowering from mid to late summer, it adds bold colour and vertical interest to pond edges when many other plants are starting to fade.
Ideal for planting in shallow water or consistently damp soil, this upright perennial works well at the back of pond margins or in bog gardens, helping to create height and structure within a planting scheme. Its intense flowers are highly attractive to pollinators, making it a great addition for encouraging wildlife.
Hardy in UK conditions, Lobelia cardinalis prefers a sheltered position and moist, nutrient-rich soil to perform at its best.
