Upright Water Milfoil (Myriophyllum crispatum)

Upright Water Milfoil (Myriophyllum crispatum)

An attractive oxygenating pond plant with upright feathery foliage for shallow shelves and wildlife ponds

Upright Water Milfoil (Myriophyllum crispatum) is an attractive oxygenating pond plant with fine, feathery foliage and an upright habit. It is a useful alternative to more vigorous water milfoils, offering oxygenating value, wildlife cover and soft texture for garden ponds.

This plant grows well as a rooted potted oxygenator on shallow pond shelves. The finely divided foliage creates useful shelter for tadpoles, newts, pond insects and small fish, while the upright growth gives more structure than loose submerged bunches.

During active growth, Upright Water Milfoil produces oxygen during daylight and uses nutrients from the water and planting medium. It is a good companion for deeper bunched oxygenators because it helps create planted cover closer to the water surface.

The plant can produce small reddish flowers during summer, although it is mainly grown for its attractive foliage and habitat value. Its texture works well alongside waterlilies, marginals and other oxygenating pond plants.

For best results, position in a bright pond with still or gently moving water. Avoid heavy shade and trim back excess growth if required to keep the planting balanced.

Potted Oxygenators and Bunched Oxygenators

Potted oxygenators are supplied rooted in aquatic soil and are usually placed on pond shelves or in shallow water. They often provide useful cover near the water surface, making them valuable for amphibians, froglets and aquatic insects.

Bunched oxygenators are usually weighted and placed into deeper areas of the pond, where they can sink towards the pond floor and root into the substrate.

Upright Water Milfoil is best used as a shallow water potted oxygenating and habitat plant rather than a loose deep water bunch. It pairs well with deeper oxygenating bunches, marginals and waterlilies to create planting at several different depths.
