Zuzu - I'm really surprised at your Charisma. Mine bloomed like a champ, got no black spot, didn't get eaten by earwigs or aphids.. and gets less than 4 hours of sun! I really love my Charisma... I was frantic to find one after I saw a picture last summer and ended up getting one off of eBay.. then, like a week later, I saw one at King Soopers (Kroger brand grocery store)! So I got the two of them & the one I got off of eBay went from a little bitty band to a decent sized plant (about 1', all things considering) even though it gets like 3 hours of mottled sun a day! Here's that plant exactly in August!
