The Intensia® Phlox series are the result of a cross between P. drummondii and a southwestern U.S. phlox species. Growth is low and cascading which makes this annual phlox ideal for planting in the front garden border. Equally, Intensia® Phlox excel in mixed containers, window boxes, and hanging baskets.
Intensia® phlox grow to a uniform 8-12” mature height in full to partial sun (best in 6 hours or more sunlight). Intensia phlox possess exceptional heat and humidity tolerances and flower freely all summer long. Insect and disease problems are minimal, exhibiting above average powdery mildew resistance.
Annual phlox thrive in well-drained garden soil which has been generously amended with organic matter. After planting, water on a 7-10 day schedule, particularly when rainfall is not plentiful.
By mid-summer plants may appear seedy and overgrown. Mow them back to 5 inches high, add fertilizer, and irrigate. The phlox bed will perk up and re-bloom within a few weeks, and right into the autumn season.
Blooms are slightly fragrance and attract frequent visits from nectar-hungry bees and butterflies.Flower colors of the Intensia® series range from white, several pink shades, lavender, and purple.
