Fort Hill, also known as Creeping Phlox, Phlox Subulata, and Moss Phlox, is a perennial flowering plant native to North America. This variety offers a creeping, spreading habit of 4-6" tall and 12-24" wide, with star-shaped, rose pink flowers in spring. Creeping Phlox attracts butterflies, resists deer and rabbits, and flourishes as a groundcover or in containers, landscape borders, and rock gardens with little more than a sunny location and regular water. Fort Hill is more drought tolerant than other varieties. Perennial and evergreen in zone 3-9, Fort Hill is an obvious low-maintenance addition to the landscape for any homeowner. For an upright variety, try Phlox Sweet Summer Compact Rose.

This plant is day neutral and benefits from 6-15 weeks of vernalization at 35-41 degrees. After vernalizing, use average daily temperatures of 59-76 and light at 4,000-8,000 fc.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
