Protea susannae is endemic to the Western Cape province of South Africa.[3][8] It occurs from Stanford to Stilbaai.[5]
Ecology
editDuring the periodic wildfires which pass through its habitat adult plants die, but the seeds can survive such an event. Pollination occurs through the action of birds. The seed is stored in the old, dry infructescence which remains persistently attached to the plant. The seed is eventually dispersed by means of the wind. The plant grows in calcareous and pH-neutral soil at altitudes from sea level to 200 metres.[5]
