    • I planted three of these Moonlight Phlox last year (2022). I had rented my small home for ten years and no care was given to the yard. Browsing the Garden Outlet, I saw these beautiful flowers and bought three. They were beautiful and lasted all season. This Year (2023) they came back over twice the size! I have had absolutely no problems with them. I have had so many inquiries on what they are and how nice they look. This year I did not see any at the garden store unless they sold out early. I am going to divide and relocate them throughout my ever-changing landscaping. Also sharing some with my neighbor. Again, I cannot tell you how many people have noticed and asked about them !!

    • I planted three of these phlox in early spring of 2022. Within a month some leaves were turning yellow and browning on the lower half. I spoke to a Proven Winners specialist who assured me that the plant would be fine. I treated them with copper fungicide and neem oil at different times. With a lot of work, they rebounded about 85%. I was very pleased to see all three coming back vigorously this year in early spring, but that was short-lived. The lower leaves up to a third of one plant turned yellow and brown. I believe there are spider mites and possibly disease at this point, but it isn't powdery mildew. I really was excited when the Luminary Blacklight phlox were available however, even though I am an experienced gardener in zone 6, Ohio, they are a lot of work.

    • These really impressed me! I planted these in May and they flowered June-August again and again which I did not expect, especially during their first season. I'm looking forward to seeing how these fill in and perform in the coming growing seasons.
