Those of you who have grown Celebrity or seen it growing.....does it need staking? Those pictures you see are gorgeous but I've never seen it in person.
Chateau CharMarron advertises this one, think it's the same, under its Chinese name. You can email her and ask about the stem strength. She seemed pretty helpful when I contacted her last fall. Good luck!
