Description and Ethnobotany

Growth Form It forms a compact, basal rosette 4 - 16 cm wide.
Foliage Oblong, bright green leaves are arranged in a basal rosette that is 4-16 cm wide. The leaves are covered in knobby glandular hairs that create a sticky surface to trap and digest insect prey. The leaves also produce antibacterial compounds that prevent prey from rotting as the plant digests it. Plantlets form at the leaf tips where it touches the media.
Flowers Solitary flower is composed of a three-lobed upper lip and two-lobed lower lip. With each lobe split in to two rounded parts, it resembles a Primula flower. The flower is light purple with a yellow throat streaked by brown veins. The leafless floral stalk known as a scape is covered in knobby glandular hairs that trap insects.
Fruits Round, 5 mm wide fruit known as a capsule contains many small, brown seeds.
Cultivation It can be potted with Sphagnum peat moss at the bottom and a mixture of Sphagnum moss and perlite at the top. The media should be kept consistently moist.
