PLUM DOUBLE - Santa Rosa & Black Doris

0 Ratings

Waimea Nurseries grows a range of fruit trees with two or three varieties on the one tree. Some fruit types are grown with both varieties grafted at the bottom of the tree trunk, while others are grown as tiers of branching. The method of propagation is based on the natural habit of the fruit types, to ensure a good shaped tree will result. The tree should be labelled with a small mark of paint to identify which part of the tree each variety is located. This also helps to avoid the potential of accidently pruning off one of the varieties!

Santa Rosa: The Queen of all plums! Developed by Luther Burbank, it is among the highest flavoured plums in the world. Medium to large purple skinned fruit with yellow tinged pink, juicy, tangy flesh. Japanese variety that can be used to make blush wine. Early to mid season.

Black Doris: Excellent all purpose plum. Fruit is of medium size, with purple black skin and dark red sweet, juicy flesh. Vigorous, up right tree habit. A Cross variety. Mid season.
