The white Obedient Plant seems to truly be obedient, unlike the purple version; which is prolific. I bought both a white and a purple pot and the purple has become a 2' by 3' border. The white one is only an inch or so fuller this year. It hasn't spread at all in the bed. The purple are spreading everywhere and I can tell I will be pulling some of those out very soon. They are beautiful together and are one of my favorites. Very easy to grow in my clay soil. We had very high winds and lots of snow this winter, too; and it hasn't hurt them at all. I only put them in last summer and I will already be giving some of the purple to friends. Love it.

Called obedient plant because the flowers, when manually moved sideways, retain the new position. The wild species is found in moist to dry prairies.
