Often, it contains one or more greenhouses, which helps shelter new plants from frosts or excessive heat. It may also include complex watering systems to cut down on the labor of workers. Most shops that exclusively sale plants are called a nursery regardless of whether they actually start and grow their own plants or purchase them elsewhere. A nursery sale plants at retail value to the public, or
exist to sale wholesale to other nurseries. In some cases, a Pinky Nursery will specialize in one kind of plant or tree, for example roses, or Japanese maples. This type may still be open to the public a few days of the week, but may primarily do business with other retailers. For the collector of rare specimens, a specialized nursery is often the best place to find a particular species of plant that is difficult to obtain elsewhere. Occasionally, a wholesaler is open to an avid collector, or can give information about where to find a specific type of plant.
