This year I finally decided to toss the Cannas that were at my front door path. I replaced them with a native Salvia 'Henry Duelberg.' I have not regretted the change one bit! The Cannas required constant care. The spraying, the watering - oy - no more! In contrast, The Salvia has had absolutely no care and has been in bloom since mid April. I did save a couple of Cannas and put them in pots. As usually however they look ratty and sad. I may let them die in their pots. I guess I do have my limits when it comes to plant selections. That at least is nice to know!
