Phlox 21st Century Blue Garden Flower Seeds

Blue Phlox (Phlox Drummondii 21st Century Blue) - Cool season plant is perfect for landscapes and mixed containers. This full sun plant only grows 10 inches tall and blooms from early Spring up until frost in this purplish color. Attracts bees and butterflies making it the perfect low growing pollinator.

Sow Phlox flower seeds directly outdoors into prepared soil in the late fall or spring. After distributing the flower seed evenly, rake into loosened topsoil to ensure good seed contact with the soil. For earlier blooms, sow the Drummond Phlox seed indoors 4 - 6 weeks before setting out. As with all annual flowers, it is essential that annual Phlox Drummondii is allowed to re-seed for an abundant display the following year. Annual Phlox care includes trimming the plant back after the first flush of blooms. A trim encourages a second bloom of Phlox flowers.

Beautiful In The Garden!

When it comes to Phlox flowers, many gardeners often agree with Karl Foerster, a horticulturist. He said that "a garden without a phlox is a mistake."
