My sister in law had one color at first. She mixed up seeds from it in her hands and threw them out. Now she has several colors. The one I have growing is a start from one of those. It's white with a purple stamen so far 😊 hummingbirds love them too.I have no idea. They were cuttings from my hubs mother. One white, one purple and one pink. I wish I had gotten seedlings, I would have been able to bring those with me.
Thanks for the offer, but I am getting some from Len.
