Drosera myriantha is a carnivorous plant from the sundew family growing up to 45 cm in length. Like every species within the genus Drosera, this plant uses its heavy glandular leaves to trap insects for nutrients. The higher the intensity of exposed light, the brighter red the leaves will be. This plant grows from small tubers in the ground. This species does not create a basal rosette. Slender stalks containing round leaves arise from the tuber in the ground directly. At the top of this stalk, small white to pink flowers are produced in summer. Propagation is most easily done by tubers near the base of a mature plant. Also, harvesting and sowing seeds is possible.

Drosera myriantha originates from loamy soils, marshes and heathland of southwestern Australia. It grows in exposed, moist areas near grassy patches. For optimal growth, the optimal day temperature is around 25 degrees Celsius. In the night temperatures could drop to 15 degrees Celsius. In spring and in summer this plant could also grow outdoors but make sure temperature does not drop under 15 degrees Celsius. Place this plant in a mineral rich, water retaining medium that lacks nutrients and other dissolved salts completely. Clean peat or horticultural sand are some examples. Provide this species with bright to very bright light conditions such as direct sunlight or strong artificial lights. Prevent this plant from drying out when actively growing. To maintain swampy or soggy conditions, it is possible to place a perforated pot in a tray of water. Always use demineralized water; water containing even a low concentration of minerals could burn the sensitive roots. Fertilizer is best to avoid but it is possible to feed this plant with caught insects once per month.
