P70929The nomenclature of horticulture, or the ‘naming’ of plants, is very similar to that of automobiles. All those confusing Latin names work just like the names of cars, with species, genus and even family. The Electra is made by Buick, which is a subsidiary of General Motors. I write an article about this every so often. It probably made more sense back many years ago, when both cars and plants were simpler.

Nowadays, it is difficult to distinguish between the different kinds of cars. There are so many different kinds, and they all look so similar. Buicks are not nearly as stylish and distinctive as they once were, and do not look much better than a well outfitted Honda! Cadillac and Lincoln make station wagons, which are now known as SUVs; and they even made pickups! Many cars have one name on the outside, and another, or a few on the inside. A Chrysler might be made by Mercedes Benz, with a Japanese engine! Many cars that had been ‘imports’ are make locally. There are so many different models that some do not even get names. They just get numbers. What is the point of trying to keep track of them all?

Plants have done the same. So many of the reliable and standard specie that had been around until the 80s have been replaced by too many modern cultivars and hybrids to count. Some have been hybridized so extensively between different specie of the same genus that they are not even assigned a specie name! They are merely known by their cultivar name. For example, Grevillea ‘Peaches and Cream’ lacks a species name because no one know who the parents were. (It might be a Grevillea banksii X Greillea bipinnatifida hybrid. See the article about it at https://tonytomeo.wordpress.com/2017/09/30/peaches-and-cream-grevillea/.) What is the point of using standardized nomenclature without the standards? This is not like Madonna or Cher, who do not need last names because they are so unique. Plants need their names more than before because there are so many new ones.

Cars have been improved in the most important ways. They are much safer than older cars. They are also much more efficient and remarkably more durable. The main problem with these improvements is that cars are so difficult to maintain for those who are not professional automotive technicians. Those of us who were inclined to maintain our own vehicles years ago must now take them to mechanics. Although vehicles are designed to need much less maintenance and to last longer, they eventually need to be replaced when maintenance is no longer practical. They are not as sustainable as old cars that can sometimes be repaired with part found in a common hardware store.

Plants have likewise been improved to do what we want them to do better. Foliage is better and more resilient, and in some cases, more colorful. Flowers are more abundant, more colorful, and last longer. Whatever plants were supposed to do before, many do better now. The main problem with all the breeding and hybridizing necessary for these unnatural improvements is that it interferes with what plants need to do naturally. Some are not able to produce viable seed, (although this is an advantage for potentially invasive plants). Others are genetically weak, and therefore more susceptible to disease and insect infestation. Perennials that once perpetuated themselves indefinitely now die out in only a few years. Plants that were once easy to propagate are now not so cooperative. Like modern cars, plants can not be maintained as long as they once were, so need to be replaced instead of sustained.
