Monday and today the classes were on Botany and were conducted at UNCC. The class Monday dealt mostly with the parts of plants and how to identify plants by their parts. Today (Wed) we learned about the naming of plants. The first name is the “Genus”. The second name is the “species”. These two names are specific for each plant and can help avoid the confusion sometimes present with common names.
Only wild plants have a distinct species name. Garden plants are mostly “cultivars”. The important thing about cultivars is that they have been either bred or selected for certain advantages. Most cultivars could not exist in the wild because they need someone (a gardener) to take care of them. It is critical that the gardener choose the proper cultivar.
One of the tools gardeners have for choosing the correct cultivar is the zone map. The zone map is based on minimum temperatures. This is why the seed catalogs list the plants as suitable for zone 3-6 or 4-8. The cultivar chosen is based on cold hardiness and heat tolerance. Rainfall and soil type is also important, but that is indicated in the zone maps.
