Burncoose (Magnolia ‘Burncoose’) Posted on April 6, 2012 by Lucile Whitman A seedling of ‘Diva’, sprengeri ‘Burncoose’ isn’t quite as large a tree, but the flowers are bigger and deeper pink. The one small problem is that a late spring frost will zap them. Size: 1 gallon Price: $30.00 Size: Field grown Price: $115.00
