Do not mistake the name of this plant to necessarily be a positive. This plant will obediently re-seed, anchor its roots real deep, and drive you crazy. It can withstand abuse such as the stalks being bent over, and the flowers will still stay in tact; maybe a good attribute for floral arrangements but not so good for your flower bed. The plant is named "obedient" due to this ability to bend the stalks in any direction you like.

The first couple years this plant was manageable in my garden...this year (2011) I battled seedlings all summer long. This Fall I finally dug all of it up but know I will be still be cleaning fragments of this plant out of my garden next year.

It can be a lovely tall plant in the right spot and with care you can reduce the amount of re-seeding. I would suggest a good ground barrier and very careful deadheading.
