Whilst there's lots of different aquarium plants available, there are only limited varities that are really suitable for coldwater tanks. And the modern definition of cold water doesn't mean super cold water - it just means unheated water assuming the aqaurium is kept in a house. In most cases, temperatures are 15C and up - any less than this and varieties drop right down to just a few.
So let's see what makes Top 5 Cold Water Aquarium Plants:
1. Elodea densa
Perhaps the most famous of them all, Elodea densa is an easy to grow plant that can handle cold water without any issues. Flourishes outside when it's warm but just slows down when it's colder. Well recommended and don't forget to trim this plant so it stays nice and bushy.
2. Hornwort
also known by cedar moss, coon tail, horn weed, morass weed, rigid hornwort doesn't mind cold water at all. Grows at a moderate pace in the cold. Often used as a floating plant, it can be planted but never grows roots so you have to anchor down with lead weights.
3. Java Fern
Microsorum pteropus, commonly known as Java fern, is a popular aquarium plant among aquarium enthusiasts, particularly for beginners. Originating from Southeast Asia, Java fern is a slow-growing plant that can thrive in a wide range of water conditions and light intensities. It is a hardy plant that can tolerate a range of temperatures and pH levels, making it an ideal choice for low-maintenance aquariums.
4. Lobelia cardinalis
Originating from North America the Lobelia cardinalis is a striking mid-ground plant reaching heights of up to 20cm. When submerged the leaves are light green and smaller than when emersed. A really happy plant will produce a white, pink or red flower.
5. Java Moss
Taxiphyllum barbieri, commonly known as Java Moss, is a species of aquatic plant that belongs to the Hypnaceae family. It is native to Southeast Asia, where it grows in freshwater streams, rivers, and lakes. Taxiphyllum barbieri is a popular plant in the aquarium hobby due to its attractive appearance, ease of care, and versatility in aquascaping. IT can also handle cooler waters too making it a great choice for coldwater aquariums.
