Lobelia siphilitica (Great Blue Lobelia) – Marginal Pond Plant – UK Grown

Lobelia siphilitica, or Great Blue Lobelia, is a beautiful marginal pond plant with stunning blue flowers. It blooms from late summer to early autumn, adding vibrant colour to your water garden. The tall, upright flower spikes provide a striking contrast to the lush green foliage.

This hardy perennial thrives in moist soil or shallow water, making it perfect for pond margins and bog gardens. It prefers full sun but will tolerate partial shade, growing best in slightly acidic to neutral soil. Keep the soil moist, especially during dry periods, to maintain healthy growth.

To plant, place Lobelia siphilitica in an aquatic basket filled with loam-based compost. Ensure the crown of the plant stays just above the water level. If planting in boggy soil, keep the area damp for optimal results. Regular watering is important during hot, dry spells.
