Trachelium

I have grown this plant several times. I seem to get a few years out of it. But I LOVE it! It's a tender perennial called Trachelium caeruleum(say Trak-EL-EE-um) or Blue Throatwort.  It is called that because it used to be used for throat ailments. It grows best for me in part shade but is said to grow in full sun too.  It is native to the Mediterranean and grows 2- 3' tall.  It is a fantastic cut flower filler.  Trachelium is hardy in zones 7-11. It also comes in white and some lighter blue/purples.  I have a friend who says it reseeds in her yard.  

Happy Gardening!
