The question was brought up so I thought I would clear it up. Tropicanna Gold is said to be a very slight mutation from Bengal Tiger. As you can imagine a difference would mean you could patient the plant. I have grown them both and truthfully I can rarely tell a difference. In some cases they are identical but here is a good photo showing the differences
This is Tropicanna Gold if you notice a yellow like ring around the petals.
Canna Tropicanna Gold And Bengal Tiger
Thank you for taking the time to answer this question, and for that matter, the time to grow both cannas to find out for yourself. It does look from the pictures that the leaf markings are slightly different between the two, also. I have the Bengal Tiger & I didn't get Tropicanna Gold because I thought it was the same thing.
And of course, now I feel like I should get the Tropicanna Gold, too!
Thanks again
The central vein and variegation on Tropicanna Gold seems more prominant and defined than Bengal Tiger. Has that been typical of any you've seen?
