'Heavenly Tiara' is a sport of 'Grand Tiara'. It's rated as medium, but mine is still small even though I've had it since 2011. Its leaves start out with a gold centre that turns to chartreuse surrounded by a very wide creamy white border. Mine was grown in too much sun in 2015 due to the loss of a large tree. I've now potted it and will try to find a better location for it this year as it faded a great deal in that much sun. Please feel free to share your pictures of this hosta.
