This fern species is originally from South-east Asia where it shares a habitat with the reptile from which it derives its unofficial name, the crocodile. Microsorum mussifolium “crocodyllus” is a strong plant with leaves that retain their robust health even if it receives no water for a time. After several years, the leaves can grow up to a length of 1 metre.

Microsorum mussifolium “crocodyllus” does not like cold temperatures or draughts so when cultivated as a house plant it should not be exposed to a temperature lower than 15 degrees Celsius. It should receive sufficient indirect sunlight or plenty of shade. As with many fern species, it should not be exposed to direct sunlight in order to prevent damage to the leaves or dehydration. It should receive enough water to keep the growing medium moist but must not be overwatered or retain water in the pot. Microsorum mussifoloum “crocodyllus” can be repotted in spring to give it more room. Its rhizomes or rootstalks will mutiply horizontally, producing new shoots and leaves. In autumn, the plant needs less water and little or no feeding.
