For Sumpfpflanzen , I recommend a minimum of 1 basket with 4 plants and a maximum of 4 baskets with 16 plants per m3 (1000 gallons of water). The amount needed depends on how quickly you want the pond balanced and your visual requirements.

Frequently asked questions about Calamus

Pond Advice

Calamus is a popular marsh plant often used in ponds because of its ornamental appearance and easy care. This aquatic plant, also known as Acorus calamus, has long, narrow leaves on which small flowers grow in spring when the plant is in bloom.

The Acorus plays a role in the natural filtration of water. By absorbing excess nutrients from the water, this plant helps reduce algae and provide clearer water.

Calamus, also known as Acorus calamus, grows naturally in moist environments such as marshes, river banks and along the edges of lakes and ponds. Originally from Asia, the aquatic plant is now found in many parts of the world, including Europe, North America and parts of Africa. Calamus can be planted in both sun and partial shade and needs moist soil to grow.

 

Calamus is a strong aquatic plant that can survive the winter and grow up to 80 centimeters tall! You can plant it at a depth of up to 20 centimeters below the water surface. Be sure not to plant the calamus deeper as it will not grow as well.

For an area of 1m², we recommend using at least 1 basket, containing 4 Acorus plants. Depending on how quickly you want the pond or water feature to balance, and depending on your own preference, you can choose up to 4 baskets per 1m².

What is calamus?

Calamus, known by its scientific name Acorus calamus, is a plant native to India and parts of Asia. The plant has a long history in traditional medicine, especially in Ayurveda. Calamus grows in wet, swampy environments and is known for its long, sword-shaped leaves and a distinctive, fragrant rhizome.

Acorus calamus

One of the benefits of adding calamus to a pond is that it helps filter the water. The roots of the plant absorb nutrients from the water, which helps to improve water quality and thus water parameters and reduce algae growth. The calamus is a marsh plant which means it does best in shallow water, plant the calamus for this reason no deeper than 20 centimeters. Because if the pond plant is submerged, it will not grow as well. Besides its functional properties, calamus is also a beautiful addition to any kind of pond. Calamus is traditionally used for medicinal purposes and is a part of Ayurvedic and traditional Chinese medicine. Furthermore, it is said to work against stomach problems and stimulate appetite. However, it is important to emphasize that not all of the plant's properties have been scientifically substantiated.

Variegatus

Calamus is characterized by its bright green, sword-shaped leaves that grow tightly in bundles from a rhizome. When damaged, these leaves give off a sweet fragrance, due to a powerful essential oil for which the plant is known. This hardy marsh plant can withstand temperatures as low as -35 degrees Fahrenheit. This plant is easy to maintain and does not require much extra care.

Where does calamus come from?

Calamus is native to parts of Europe, Asia and North America. This aquatic plant thrives mainly in marshy areas, along rivers and in ponds. Today, due to human activity and horticulture, the plant can also be found in other parts of the world.
