This plant was introduced to Race Rocks by Assistant keepers in the 1980s. From a small flower bed near the assistant’s house It has spread over much of the Great Race Rock Island. Since it is a member of the Crassulacea family, it uses the crassulacean acid metabolism (CAM) method for fixation of
Carbon Dioxide for photosynthesis. Since it can fix Carbon into a chemical when stomata are open only when its cool at night, it is very resistant to drought, and can survive with very little soil.
It is of course not the only introduced species on Race Rocks but since it is not grazed by anything, it is rapidly replacing the sparse growth of native species such as thrift and grasses in the rock crevices.
