Drosera collina is a large, rosetted tuberous sundew endemic to southwestern Western Australia, particularly along the Darling Scarp east of Perth, extending south toward Bridgetown, with isolated populations in the Stirling Range. The species name "collina" comes from Latin, meaning "hill," reflecting its preference for well-drained, hilly terrain in open Jarrah (Eucalyptus marginata) forests.
 
This perennial sundew forms flat rosettes with 10–12 oval to slightly elongated leaves, reaching up to 10–12 cm in diameter. Leaf coloration varies from green to orange, depending on light exposure and seasonal changes. D. collina enters summer dormancy, surviving through an underground tuber, and resumes growth in autumn, when it produces clusters of white flowers on short, branching inflorescences.
 
It is closely related to other members of the Drosera erythrorhiza complex but can be distinguished by its numerous, elongated leaves. Unlike some tuberous Drosera, D. collina does not rely on bushfires to flower and rarely reproduces via stolons.
 
Available 1st October to 15th March.
 
Price is for a dormant Tuber.
