perennial phlox

Perennial phlox refers to garden phlox varieties, primarily derived from the North American species Phlox paniculata. These plants typically feature erect stems that grow 2 to 4 feet tall, with opposite leaves measuring 3 to 5 inches in length. Their flowers are distinctly stalked.1

Phlox, as a genus, includes about 65 species, most of which are native to North America. These plants can be either annuals or perennials and are known for their clustered, often fragrant flowers that come in various colors, including white, blue, purple, pink, and red. Summer phlox (Phlox paniculata) is a notable species, sometimes exceeding 1.5 meters in height with large, flat flower heads.2
