difference btwn Rozanne and Ingwerson
Hello. My landscape architecht recommended I plan Ingwerson geranium, but upon looking at some pictures, I like the blue geraniums like Johnson's Blue and Rozanne better. I did some research and found out that Ingwerson is a microrrhizum. Are Rozanne and Johnson's Blue the same thing? Is there some reason why you'd plant Ingwerson and not the blue varieties? And, what is a microrrhizum? lol...thanks for any help!
