Gardeners' Notes:


On Jun 3, 2014, coriaceous from ROSLINDALE, MA wrote:

The species is generally quite mildew resistant and more vigorous than the cultivars. Height varies, but some forms can reach 6' tall. Even the tallest rarely need staking. Flowers are usually magenta.

Despite the common belief, most of the cultivars are selections of P. paniculata and few if any in commerce today are hybrids. In buying them, I consider resistance to powdery mildew first.

Performance is generally best with regular division every 2-3 years. Plants are best divided in early spring before they reach 6". If you have to divide later, the top growth should be cut back to 6". I don't recommend fall division.

Seedlings of cultivars can give interesting results, but if allowed to self-sow freely eventually tend to revert to type, with m... read more

This one is the 'Texas Pink' cultivar, bred to take the hot humid Texas summers and supposedly resistent to powdery mildew. That certainly has been my experience, I have never seen a single speck of that stuff on these babies. They are continuing to thrive and spread with a real minimum of care, close to ten years since I planted them there.

Didn' t thrive in my area, obviously needs cold at dormancy period.

Garden Phlox has always done okay for me. They looked good for awhile, powdery mildew hit, they flopped, blooms ended, I cut them back. But last year I did something different, and I don't know if that is what helped or if it was a coincidence, but they were amazing! In the early spring, while they were still fairly short, I thinned out a lot of the smaller stems. I know that would help make them stronger and reduce powdery mildew, but what was amazing was they bloomed continuously for months. As the blooms would start to fade, new ones would form in the old clusters. I never deadheaded them, never fertilized them, nothing. No powdery mildew, no flopping. I will definitely thin them again. Blooms July-September in my garden.

Found this plant to be susceptible to powdery mildew (even the "disease resistent" cultivars) in Virginia - zone 7. HOWEVER, it is gorgeous and has a very long bloom time with regular deadheading. Adequate spacing is enough to keep most of the mildew threat at bay, also try to avoid watering from above. Water at base of plant. Given room for air circulation, this plant is fabulous. Bonus: it attracts Black Swallowtail butterflies :)

A perennial plant with fragrant pink or white flowers in summer. Likes a moist and well drained soil in full sun to light shade. Divide clumps every 4 years. Very cold tolerant. Great for lightly shaded woodland gardens. pokerboy.

The unimproved species is magenta in color, but many cultivars have been introduced in a wide variety of single and bi-colors. The species has good mildew tolerance, as well as compact plants that seldom need to be staked.

Grow this by silver-foliaged plants to make it a good neighbor.
