In the spring of 2011, Minot, ND was devastated by a flood. All the plants were under river and sewer water the entire summer. The next spring of 2012 my daughter, Laura, passed away. Shortly after her funeral we noticed one tiny plant peeking thru the ground. It was the Laura phlox. The only plant in the entire yard to survive the flood.

I agree, 'laura', variety phlox are very beautiful, although it's one of the more common varieties, this is where to start, it is one of the hardiest varieties, has that beautiful white double tone translucency around the purply pink bloom centers, and is still my favorite as it was the first phlox i had in my garden. mike.

A beautiful plant! Atleast in zone 7, it's important to give garden phlox room to promote air circulation and discourage powdery mildew. Also, a good idea to avoid watering from overhead, water at the base instead. Otherwise, absolutely lovely! Deadhead regularly for a long bloom season -- snapping off individual cluster when most of it is spent.

Love this phlox! It's a bit shorter than most varieties and better suited for the front or middle of the flower border. The color is bright and cheery and the flowers last several weeks in the garden. My plant has made a nice, sturdy clump after a couple of years and it puts on a nice display of color in the late summer.
