Hard Rush Juncus Inflexus - 1L Pot

Juncus Inflexus is a tall emergent perennial plant, native to Britain, which helps to maintain optimal pond water conditions and naturally streamline its filtration processes. It also has highly decorative properties, which makes it a versatile plant, suitable for beautifying pond margins and water-flows. This tufted rush features dense clumps of slender, grey-green furrowed stems and brown inflorescences from late spring to mid-summer. It provides a good habitat for emerging dragonflies and other pond life. Juncus Inflexus is an evergreen plant, which means that the foliage of the plant persists and remains green throughout the year.

Plant in a medium sized pot with up to 24cm of water above the planting basket or in the damp soil. Plant spacing: approx. 30-50cm. Aquatic and marginal plants should be placed in pond plant baskets filled with aquatic soil (sold separately) and topped with a thin layer of gravel to help prevent the soil from washing away. This plant is suitable for zone 2 of a pond.

Caring and Maintenance:

This is a very low maintenance yet vigorous pond side plant which spreads to form large clumps quickly. Propagate by division or grow from seeds in spring. Large clumps can be planted directly into soil. Smaller clumps should be grown in a cold frame until they are rooted well. All wandering clumps can be trimmed to control plant growth. To maintain the look of the plant and to control its self-seeding, the dead stems should be cut after flowering.

Please Note: The parts of Juncus Inflexus are toxic.

Our range of filtration plants include varieties that have been specially selected for their excellent ability to absorb toxins and waste products from the water. Their roots grow into dense underwater mats, nature's way of filtering the pond water to keep it clear and sweet. They also help in attaining a natural, balanced pool without using harmful chemicals. These water-plants are now used extensively throughout Europe by water authorities to treat raw sewage before being released back into the environment. This collection offers a cost-effective natural filtration system.
