Gardeners' Notes:

What a great flowering tree! Most people experience 'Coralburst' crabapple as a top grafted "cueball on a stick", but take a look at the posted images in this entry.

'Coralburst' crabapple, with its fine tracery of branches, offers a form and texture to rival Japanese maples for those colder climates where Acer palmatum has no chance. The flower show goes without saying.

Mr. Ross did some wonderful work with crabapples, and his legacy lives on in selections like 'Coralburst'.
