I believe that is the correct name. It has been growing quite happily for the last three years in it's shady spot in my garden - adequate light - but now it looks as though it has died - only two healthy leaves the rest are shrivelled and brown. There is also an astilbe that has the same dead look although this is not directly next to it. Can anybody help as to what this may be or and how to save my acer. JXP
