Love it! Yes it's 2011 but my Thistles are growing great and keep gettting bigger and bigger! I have even divided one out last year and gave it to a friend and it did survive! I never see these offered at nurseries but ya gotta have one! These were ordered from Van Dyck's way back in 2002 so you can see how hardy they are!. They are in an island garden with a good amount of sun, when the plant goes into bloom they are just loaded with flowers and fragrance! They get about 4ft tall and what a contrast next to the red Bee Balm they grow next to. A word of caution, you may not want to plant this near any sitting area as the bee's do love this plant and are all over it. I can't say I have ever seen a hummingbird or hummingbird moth hang out but the bee's sure do! Check my photos out from 2010
