This pretty and delicate British native oxygenator has small rosettes of green leaves, approximately 3cm across, which float on the water surface, with fine stems below. It is a good oxygenator for small spaces, as its growth is not particularly fast, its foliage is soft and dainty, and it is easy to control. Its fine foliage will not compete well with algae, so it is better either in an established pond, or in a shady place. If it is going in a new or sunny pond, check it occasionally to ensure it is not being swamped by algae. It is also not really suitable for ponds with fish, or at least any fish other than very small ones, due to its very soft foliage.
We grow these in fairly shallow water here at the nursery, so would recommend having no more than 6 inches of water over the pot at first. If you would like the plant to go deeper than this, lower it gradually, allowing the leaves to reach the surface each time before lowering it again. (House bricks can be used to raise plants to the required level).
Please note that these are potted plants; Callitriche is usually sold as loose stems because these are easy for nurseries to crop and sell, but this is a delicate plant and loose stems are difficult to get to take.
If designing a planting scheme, we recommend approximately 1 - 2 Callitriche plants per square foot of water surface. Read more on how to pot and care for your plant.
