I am ordering cultivars that reach between 5 and 7 feet tall, I think one is the poinsettia cultivar with neon leaf colors on top. I've never grown them before but I'm afraid they will be too tall to grow in front of my house so I was wondering are the roots really long/deep and can they grow in pots and as they get larger put into larger pots.

In large containers, such as 20 inches or more, I think they will do fine.

I agree

When I pulled my clump of 6 footers at the end of the season the root mass was fairly large but not nearly as deep as I expected it to be. You may want to add plenty of sand or gravel to the bottom of the pot though, mainly for heft and wind stability. Smiling
