Splendens, known as Azolla filiculoides lomk., Differs markedly from A.imbricata (Rexb.) Nakai, a reddish duckweed that was marketed in previous years. Small green fine individuals, the main stem length, loosely arranged branches, leaves more, more and more slender. Reproductive methods are sexual and sexual two.

First in the pots fitted humus soil and manure mixed with fertilizers, in the frozen soil before the choice of hypertrophy leaf color red and green, branched arrangement tight
