The LUMINARY™ 'Backlight' Phlox paniculata or tall garden Phlox adds height and beauty to any landscape. This stunner tops out at 28 to 30 inches tall and boasts pure white flowers that grow in well-defined panicles or clusters. The fragrant flowers bloom in mid to late summer and sit on top of tall stems dotted with dark green foliage. This plant is a perennial in USDA growing zones 3 through 8.
This upright plant is commonly used as a thriller in containers, and it can also grow in borders, landscapes, and mass plantings. The pure white flowers provide a nice contrast when planted near other blooming plants, and the striking blooms make excellent cut flowers. The Phlox paniculata is native to North America, so it does not require much care once it settles in. This variety is disease-resistant for added convenience and peace of mind.
Luminary™ Backlight Phlox Care
Phlox thrive with plenty of direct sunlight. This plant can live in part to full sun, so it needs at least 4 to 6 hours of daylight, but the more, the better. Soil should be acidic or neutral and well-draining. Phlox prefers consistently damp conditions, so water then the top layer starts to dry out and spread mulch around the base to retain moisture. Regular fertilization will promote new growth and blooms.
Most varieties of Phlox are prone to powdery mildew, and while LUMINARY™ 'Backlight' Phlox paniculata is disease-resistant, it is still best to take steps to avoid mildew and fungal infections. Space Phlox when planting and thin them out if they become too thick. Also, water the ground and not the foliage. In preparation for winter, cut the plant back once the flowers fade. If you want the plant to reseed, wait until the fall to trim the plant back. Cover new plants with mulch for the first 2 winters to help protect the roots from chilly temperatures in cold regions.
Luminary™ Backlight Phlox Spacing
Tall garden Phlox grow 28 to 30 inches tall, so plant them in an area where the flowers will be on display, but the tall stems will not block smaller plants. Space plants 20 to 24 inches apart when planting. With time the plants will fill in, and giving them space allows for improved air circulation.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
