I have a small planting of Chasmanthe floribunda which for the past two years has produced the usual plants and one giant, almost 2 m. tall. The giant appeared again this year and has now produced a large number of bulbils on its stem. It flowers at about the same time as the others in its clump, with no appreciable difference in the flowers. I cannot figure out what I have here. Any ideas? Shirley Meneice
