The leaves didn't even discolor like the Adeniums beside them. As long as they were in full sun, the cold and subsequent wet weather didn't seem to be detrimental. The fact that Boswellia grows from root cuttings is at least encouraging for the immediate propagation of the plant. Since root material will produce adventitious shoots, it is hoped that root material can be introduced into tissue culture which will be a significant future project. We have one plant growing in a large pot in the enclosed atrium of the Science Lab Center against a south-facing wall.
Temperatures there are considerably higher due to all the reflected heat and light.
Night temperatures may be slightly moderated by radiative heat coming from the building. As the photo shows, the plant is doing well. So far, no flowers have been produced. When the plant flowers, be sure that photos will appear here. According to Nora Martinez, who has done extensive work on the Burseraceae, Boswellia carteri , is synonymous with B. sacra .
