Species identification within the genus Brugmansia is a persistent problem for growers of these ornamentals. Considering the chaotic manner in which many retail plant companies list them, and the vastly different taxonomic conclusions of experts, it is no surprise that gardeners can find this topic frustrating. Here are two examples highlighting this situation: First, a well-known mail-order seed company, Thompson and Morgan, incorrectly lists datura as Brugmansia. Second, within the genus Brugmansia, authors over the last two centuries have concluded that anywhere from three to 24 species exist. Justifiable reasons for all of this confusion are the high degree of variability within individual Brugmansia species and the broad range of intermediate forms that arise from hybrid crosses. Of course, it is reasonable to expect companies in the business of selling such plants to correctly identify them. Those who do not are lazy, careless, inept, or are intentionally misrepresenting the plants. In the early 1970's, Dr. T. E. Lockwood reconciled much of this confusion as part of his doctoral Summary descriptions of the species and named hybrid crosses follow. When used in conjunction with |
