Pollination

self-sterile – needs a pollinator variety

Given in thirds of a month (early / mid / late) for the northern hemisphere in a temperate climate; altitude and season shift them.

Fruit

Culinary and dessert apple (grade 3+). When well-ripened, slightly almond- to marzipan-like aroma; sweet with hearty acidity.

Growth

Vigorous at first, later only medium-strong to weak. Crown tends to be uneven: upright at first, later broad-globular with hanging side branches. Short fruiting wood - short fruit spurs and darts evenly spread over side branches and main limbs. Prone to pre-harvest fruit drop.

Yield

Yield sets in early, high to very high, regular.

Notes

On heavy, dense soils quite prone to canker. Stores about 2 months.

Care

Regular annual monitoring cuts; rejuvenate fruiting wood in heavy-crop years. Pick early and in several passes because of pre-harvest drop. Cut out canker on heavy soils.
