Pollination:Insects

Phlox (pronounced "flocks") is a genus of 67 species of annual or perennial flowering plants. Some species flower in early spring while others flower in summer into fall. Most species are native to temperate North America but a few species are also from northeastern Asia. They are found growing in diverse habitats from alpine locations to open woodlands and prairies.

Description edit

Phlox range in color from pale blue to bright red to white, though cultivars have been bred for purple and deep blue. Some species such as Phlox glaberrima (Smooth Phlox) grow to 1.5 m tall, while others, such as Phlox stolonifera (Creeping Phlox), form low mats only a few centimeters in height. Seeds are in a 3-celled, valved capsule, with one seed to each cell.

The flowers are 5-lobed, with a tube below the lobes. The flower buds open by untwisting.

Growing conditions edit

Phlox is best grown in fertile, well-drained soil, exposed to partial shade to partial sun.
