Roggeveld

The Roggeveld for our purposes is an area that extends from Calvinia southward along the Roggeveld Escarpment to the foothills at Matjiesfontein. It is a very dry area with most of the rainfall occurring in winter. Rain averages 125-250 mm (5-10 inches) a year with the escarpment getting the higher amount. There are summer thunderstorms, but these amount to only about 20mm of rain. The Roggeveld is a fairly flat, rocky plain with isolated steep sided mountains. Winter temperatures are cool and frost and snow is usual. In fact Sutherland in this area is one of the colder spots in South Africa. The best displays of bulbs occur along the edges of the Escarpment and the Hantamsberg, a flat topped mountain at Calvinia. Soils are fine grained from shale or dolerite.

Most years members of the Indigenous Bulb Association of South Africa visit Middelpos in the spring and stay there for several nights in order to look for plants during the day. They visit the Komsberg on the way coming or going and many farms in the surrounding area. These pictures taken by Bob Rutemoeller and Mary Sue Ittner were taken on one of those trips.
