About Drosera zonaria Planch.
Drosera zonaria Planch. grows as a tight rosette roughly 5 to 7 cm in diameter, with 20 to 30 green to red leaves arranged in concentric layers. Its leaves are typically 1 cm wide, generally described as kidney-shaped, and have crimson leaf margins. This species grows in deep silica sands within open woodland or coastal heathland. It only flowers after a bush fire, and this flowering pattern is speculated to be triggered by the release of ethylene. Its white, sweetly perfumed flowers, which strongly resemble the flowers of Drosera erythrorhiza, emerge on scapes that are 4 to 5 cm tall. Like most other tuberous Drosera species, D. zonaria dies back during dry summer months and retreats to a fleshy tuber located 10 to 30 cm below the ground.
