Glyceria maxima is a vigorous, moisture-loving, rhizomatous perennial grass. When young, its narrow, strap-shaped leaves are bright green. Its attractive purplish-green flowering panicles bloom in mid to late summer. Glyceria maxima associates particularly well with pondside plants, such as hostas, astilbes, or candelabra primulas.

Caring and Maintenance

Plant in moist or boggy soil in spring and add to planting baskets. In summer, plant in fertile, moisture-retentive soil. Cut back in autumn, after the leaves die down. Divide and replant in spring to avoid congested plants, and plant container-grown plants in a sunny position.

A perennial is a plant that lives for more than two years. Perennials are flowering plants which grow and bloom over the spring and summer and then die back every autumn and winter. They typically grow structures that allow them to adapt to living from one year to the next through a form of vegetative reproduction rather than seeding. Perennial plants often have deep, extensive root systems which can hold soil to prevent erosion, capture dissolved nitrogen before it can contaminate ground and surface water, and outcompete weeds. They grow very well in conditions that are poor in resources due to their earlier emergence in the spring, and the development of larger root systems which can access water and soil nutrients deeper in the soil.

This plant is suitable for zones 1 & 2 of a pond.
