I bought some plants last summer from Pepper's Greenhouse's online store - Accents for Home and Garden. I had never heard of them and took a chance. I would buy from them again. You have to scroll down.

These are three plants bought in August. Right now, it is in my 100-year-old basement under lights. The pattern wasn't strong when they came but it developed right away.
