Gardeners' Notes:

I bought a small pot of this Phlox at a local flea market 4 years ago. It was unknown to me at the time. I identified it later as a moisture lover and decided to place it near my gutter runoff. The area is sufficiently moist and also shaded. The patch has widened gradually and is quite lovely in summer. I hope to divide it this coming season and try some in another location. I have not noticed any self sown seedlings (yet).

I got this plant from my mom not knowing what it was. I planted it in full sun 3 years ago and it is still going strong there much to my surprise. In July it looks kinda ratty but the spring bloom is fantastic. However, it will spread. It has overgrown an echinacea I had next to it and I will have to pull some out this fall.

Positive Malus2006 On Dec 21, 2008, Malus2006 from Coon Rapids, MN (Zone 4a) wrote:

I think this plant can be easily moved but it tend to have its own strange habits - it will seed itself in low spots, spread to make a thick patch in one location then after reaching its peak, will suddenly decline - disease or bugs may be a factor, and they seem to be fickle about certain location - they don't like too much sun but they also don't like too much shade. Bugs seem to like to take bites out of their leaves later in the season and they look uglier later in the season but their flowers is worth it!

I love this plant when it blooms in the spring. I have had success transplanting it to other shady, even dry locations. I would like to get other colors and I am having trouble finding it.

For years I have been crossing the creek next to our
home to transplant this wonderful little plant back to the
gardens and near the hosta in a shady area of our yard.

It is such a delight with such a sweet smell. It reminds me
of lilac in a way. This morning I crossed the creek once
again, and though I don't feel like digging any up right now,
I do enjoy gathering large bouquets of it. Once you put
a group of them in a small room and close the door, a
burst of fresh spring scent greets you upon entering.

Always welcome in my garden. Wish I had more of it.

Wonderful little patches of intense blue greet me in the woods and along creekbanks here in west KY in early April. The Phlox divaricata tends to favor open woodlands and partially shaded meadows here. It likes the damp creekbanks and is often seen growing up through the fallen leaves from the previous season.

It's range is from Ontario, Quebec, and VT, south to FL,west to TX and north to NB and MN.

It is quite common here in west KY and the lovely scent drifts for quite some distance. Even these wild plants have an intense aroma.

A wonderful choice for a natural woodland garden.

This is my favorite plant for the shade garden. I have different shades of blue ranging from almost white to purple, and the billowing waves of blue are lovely.

It self-seeds easily and cuttings are easy. Plant transplanted seedlings a couple of nodes deep.

A good groundcover plant in shady areas.

Positive DianaF On Apr 7, 2003, DianaF from Owens Cross Roads, AL wrote:

If you like blue you will love this plant. It spreads thick and low to the ground. When it blooms in late spring just after the tulips, the flowers are on spikes about 8" tall and make puffs of blue.
