Appearance

Plagiochila species have a unique thallus structure that resembles a leaf. The thallus is divided into two parts: the upper part is called the dorsal lobe, and the lower part is called the ventral lobe. The dorsal lobe is larger than the ventral lobe and has a green color due to the presence of chlorophyll. The ventral lobe is thinner and has a brownish color. The thallus is usually less than 1 cm wide and can grow up to 10 cm long.

Common Pests & Diseases

Plagiochila is generally free from pests and diseases. However, if the soil is too damp or the plant is exposed to too much sunlight, it can attract slugs and snails.
