"sure" ...??? I received Hot Chocolate from Burlington Rose Nursery this Spring. I was told this rose is similar to Smoky which was/is out of stock. According to her Spring availability catalog she does not offer Hot Cocoa. I have to agree with you that it does look a lot like Hot Cocoa but I believe there may be a difference. I don't know all the rose lingo - so you will have to bear with me. Here's 2 pics - 1 of Hot Chocolate and 1 of Hot Cocoa as they are begin to bloom (open up). If you look at the lower petals you can see the colors differ. I tried to match the text writing with the darkest part of each rose. The lower petals on Hot Chocolate is more uniform in color. The lower petals on Hot Cocoa are more blotchy. It's not until Hot Cocoa opens up more (matures) that the color becomes more saturated. You may see this better in the photos on the database. I am not 100% positive about this, however, as I recall, the petals on Hot Cocoa are thinner. The petals on Hot Chocolate are more substantial - thicker. Both leaves appear shiny. Although Hot Chocolate's leaves appear a lighter green in color. Keep in mind the plant may require more nitrogen or iron??? These are my present observations. If my observations change I will update. As I said previously, "I have to agree with you that it does look a lot like Hot Cocoa."
