We offer azolla for sale and ship directly to approved climate zones. Azolla is a nitrogen-harboring true fern that is able to multiply its weight three times each week during the summer months. It is a small, flat, diminutive, moss-like floating water plant that floats freely on the surface, often forming extensive reddish mats. Young Azolla is generally bright green, becoming pink, red, or dark brown as the plant matures and when exposed to strong sunlight. Upon close examination, these floating water plants consist of many tiny ferns with multiple pairs of individual overlapping scale-like leaves that resemble a cedar leaf. Each plant may have a branching stem with several pairs of leaves, but only a single dangling root. Azolla is an excellent source of supplemental food for koi and goldfish, or looks especially good when allowed to root and grow on the moist ledge of a waterfall or stream.
Aquatic Plants & Snails are excluded from free shipping offers and will ship separately from all other items. Please click here for shipping rates.

Mail Order: What To Expect
Plants you receive by mail need time to adjust. Your plants will arrive as: Bare Root (only root and little to no foliage), Bunches (several stems or groupings of plants) or as a Net Pot (roots with some foliage). Upon arrival, they may not appear lush but given time & proper care, they will flourish!
Simply place in water and plant will float freely.
Fertilization is typically not needed for Azolla as they take excess nutrients from your pond water. If needed, Microbe-Lift® Bloom & Grow™ can be used.
For best results, trim or prune as leaves begin to turn yellow or brown, remove them completely, discarding them to keep as much excess organic material out of water-body as possible.
In Zones 6 and lower, discard Azolla after the first hard frost.
Here are the replacement parts for Azolla.
