Wiki Draft

Manchester Steri-White is described as a sterile white flowering apple rootstock or frame tree with unknown origin or parentage. The source associates it with Manchester and prints a 1990 reference, while also saying it was discovered about 1975. [S1]

It is noted for very vigorous upright growth, strong branches, and large clean leaves. The tree is described as an ideal hardy frame tree because it blooms every year, including on new wood, but reportedly does not set fruit. [S1]
