The tree is exceptionally vigorous. The crown is widely spread with high bearing branches. It does not break under the weight of crop. Abundant in bearing wood. Bears on fruiting spurs and one-year-old branches. The flower bud contains 1.3 flowers on average. The leaf is large, ovate, deep green, glossy, with pronounced venation. The flower is large, white, with well-developed flower elements. It is partly self-fertile. Flowers approximately with 'Stanley'. Excellent cropper even in years with late frosts. It is somewhat more susceptible to the causal agent of fruit rot (Monilinia laxa Aderh et Ruhl.) in some years. Tolerant to Plum pox virus. Highly compatible with Myrobalan seedling rootstock.
