Tall Garden Phlox

The very dark, magenta violet flower panicles of 'Ultraviolet' are held above a full, bushy habit of bright green foliage. This phlox is an improvement on the industry standard 'Nicky', with darker stems and buds, bronzed leaves, more floriferous performance, and better resistance to powdery mildew. 

Tall Garden Phlox are a favourite in the summer garden, but many gardeners have been plagued with powdery mildew on phlox and are reluctant to plant it.  The new Luminary series of Phlox are selected especially for their improved mildew resistance over typical Phlox paniculata varieties. With beautiful colors and incredible performance, these are varieties to plant and watch them grow, with little work required.

Growing and Maintenance Tips

Phlox needs rich, well drained soil that does not dry out to look its best. It is a heavy feeder so a fall mulch with compost is beneficial to keep up the organic level in the soil. The varieties we sell have mildew resistant but do not overcrowd this plant. It needs good air circulation.
