@cruiser@merrelyn Thank you for commenting ladies. You're right, it is very unusual and it does look tropical. I wasn't familiar with it until 2 or 3 years ago when Chris planted some. We had some in other shades of pink and red but this one is clearly the most robust and is the only one which survived but I love it.
@bigmxx It's very pretty and unusual with the two tones isn't it.
