Hi. I'm new to calla lilies. But I bought one from dutchbulbs.com that is called Picasso. It is supposed to be plum and cream. It isn't blooming yet so I can't confirm.

My plum pretty hasn't bloomed yet either, but I thought it is supposed to be a dark rose color. The Picasso and Purple haze are nice purple colors. The Anneke photo you see advertised is not the true color.
There are no blue callas as yet.
My best dark purple last year was a variety called cream lavender, it was supposed to be cream with lavender edges but was completely dark purple. I'll add a link to my website so you can see my colors.

Here is a link that might be useful: purple callas

HI honey bunny thank for the link this has been very helpful for the colors I would like to know if picasso really comes out that color i have about 50 callies I also started some by seed and it came from a pink cally but maybe I will get different ones cause they are not allways true to the mother bye for now anna lisa
