Once I spied a clump of lavender in the woods along a roadside and when I stopped found they were some wild species off phlox. I illegally dug some and as punishment, I think, they have spread far and wide almost twenty feet and are impossible to eliminate. They spread by roots, long hairy ones and if you pull them every blasted hair sprouts a new plant. On the other hand, I found some small boxes of phlox Laura in our super market for three something. I bought one. They were small live little divisions. It died. I got stubborn. I bought another. It died. Over thirty dollars later I tried potting one up and finally got one to live. It has taken over five years for that plant to form a clump but now it is too thick and looks beautiful but is hidden behind a huge clump of cone flowers. Two years ago I decided to learn how to pollinate it and cross it with a clump of a late white phlox-finally got about twenty seeds that remain in the refrigerator as I'm not sure how to germinate them. I shall try again this year and maybe just plant the seeds outside or learn to winter sow them.--Weedy
