Alisma consists of herbaceous perennials that grow from rhizomes and thrive in moist environments. They feature rosettes of elongated, elliptic leaves that are borne on long stalks. In spring, the plants produce open clusters of small flowers, which can be white or pink.

Alisma gramineum

Alisma lanceolatum is a perennial aquatic plant that thrives in shallow water, with its roots anchored below the surface while its leaves and flowers extend above. This species typically reaches a height of 70 cm and spans about 25 cm in width. Its leaves are lance-shaped, measuring between 12 and 40 cm in length and 1 to 3 cm in width, arranged in a rosette at the base. Submerged leaves are generally smaller and exhibit fewer veins. From June through August, it produces clusters of small, three-petalled flowers that are pinkish-purple in hue, arranged in circular formations along branching stems, with blooms opening in the morning.

Alisma plantago-aquatica is a perennial plant that thrives in wet, marginal areas. It produces rosettes of grey-green foliage that can reach lengths of up to 30 cm. In late spring, it sends up tall flower stalks adorned with white blooms that measure around 1.5 cm in diameter.

Baldellia

Baldellia ranunculoides is a native perennial herb that thrives in wetland margins. It features narrow green leaves that cluster together, and during the summer months, it produces small flowers characterized by three pale lilac or white petals surrounding a yellow center.

This genus comprises only three species of aquatic plants native to extensive regions of Europe and the Mediterranean. The leaves exhibit an oval to lanceolate shape and are positioned above the water's surface. The flowers are diminutive, featuring a pale lilac hue with a yellow center.

Luronium natans is a marginal aquatic plant that thrives in shallow water and boggy conditions, primarily found in the UK, though it is considered rare. This species features small, oval, dark green leaves when situated in shallow water, while its leaves become narrower and longer as water depth increases. From May to July, it produces small white flowers with three petals and yellow centers. For optimal growth, maintain a water depth of 5 to 10 cm (2 to 4 inches) over the crown, although it can adapt to depths of up to 4 meters. It is well-suited for smaller ponds.

Sagittaria comprises both marginal and submerged aquatic plants, which can be either tuberous perennials or annuals. These species feature linear, lanceolate, or arrow-like foliage and produce clusters of white, three-petaled flowers during the summer months.

Sagittaria sagittifolia, commonly known as arrowhead, is a perennial aquatic plant characterized by its arrow-shaped leaves that emerge above the water's surface. The leaves are oval and float on the water. Flowering occurs on stems that can grow up to 80 cm tall, producing blooms in July and August. Each flower measures approximately 3 cm across, featuring three white petals that have a purple coloration at the base.
