I saw this on the weekend and took a few shots of it. I haven't seen one like this before - not as fine a flower.
So bright a colour on such a drab day.
Definitely a hibiscus! I visited a botannical garden in Hawaii once and was told the name of these, but can't recall now. Tried to google it to no avail. It'd be wonderful if someone has the name...isn't it lovely?!
