Firethorns

Formosan firethorn (Pyracantha koidzumii) thrives in most climates but prefers drier climates in soil with good drainage. Originating in Taiwan, this plant moved across the globe and is now considered an invasive species within the United States. It is known to have a vigorous growth rate through natural seed drop (which is when birds eat them and then translocate the seeds after digestion). This plant has a history of being used in several different ways for landscaping, such as an informal hedge, background plant, or ground cover.
