As the source, a few points.
--this one tends to clump. Some of our best besseae grow like trees, so I would say that the relatively short inter-growth distance is illustrated in this picture ("tree" besseae have been discussed at length on this board, I think)
--there has been much discussion about how besseae clumping is affected. It appears to be strongly influenced by genetics and environment
--I did cross this exact one to another clumper, so hopefully we get more compact plants
--the plant looks good. The new growth is strong. Watering besseae every day is a good approach with clean water.
