About

Water-plantain is a long-stalked, tall, aquatic plant that is often found in shallow water or along the muddy banks of slow-moving watercourses. It is in bloom from June to September, displaying small, pale lilac flowers and thin, branching stems. These stalks become hardy and woody once the flowers have died. Like other aquatic plants, it offers resting and sheltering places for aquatic insects like caddis flies and alder flies.

How to identify

Water-plantain has oval leaves with long stalks and parallel veins, and small, pink-tinged flowers that sit in loose clusters on branching stems.
