New to Canna's
So I've just picked up a few of those for containers placed around my pool. (Canna var. Phasion) I think they are fantastic looking. I have a few that have bloomed and am wondering if after they are done blooming, if that particular "stem" is done flowering?
It appears that once a growth blooms, that's it for that growth. Am I correct in assuming that?
Also, if this is the case, do they just continue sending up new shoots that subsequently bloom all summer long? Should I cut down the spent stems after blooming to encourage new shoots?
