Phlox stolonifera is one of my favorite phlox. It is a great ground cover in light to medium shade, that creeps slowly outwards, creating a fairly dense mat that will cover anything unsightly in its path. OK maybe not anything, it is not aggressive, but if it could ultimately replace my lawn I would not complain one bit.
Look at its flower buds. Pointed like tiny ballerina slippers. See how they are swirled shut, waiting for the right conditions to unfurl.
Then, pop, they are open. You never see it happen, it is magic. The wondrous magic of nature.
Nature and science, or the science of nature. Some would say it is physics that describes the motion of the tightly bound petals opening like an unwound umbrella.
Then there are the leaves. A mid green in pairs, like hands raised to the sky. Hundreds of tiny hands. Some hold a flower stalk a few inches above. Why some and not the others, I do not know. It probably has something to do with chemicals. There's that science again.
Here is what it looks likes when phlox covers the earth like a carpet. Happy phlox under a black walnut tree. Spread little phloxes, spread.
