Cleome droserifolia is a perennial shrub that can survive in periods of extended drought at medium altitudes of the mountain. All observations were in the rocky upper reaches of wadis in sandstone rock. It was noted in several locations in the upper reaches of Karkur Talh, including a rocky ravine high up on the side of the Hassanein Plateau. The young shoot observed in upper Karkur Talh in 2006 was probably the produce of the 2005 rains. A single example was also observed in Wadi Wahesh and in the wadi to the east of it. It was not seen in the western granitic part of the mountain with the exception of an Eastern tributary of Wadi Waddan, forming the granite / sandstone divide, but here too sandstone formed the majority of boulders in the valley.
