The tree is vigorous, with a wide spreading crown of medium density. Shoots have long internodes and matte yellowish-brown leaves. Flowering occurs in mid-season; the variety is self-sterile or partially self-fertile.
Fruits are of medium to large size, weighing about 32 grams, with a round or slightly conical shape. The thin, dark purple skin is covered with a thick bluish bloom with small light-colored dots. The variety is noted for its versatility and regularity of yields, which can be inconsistent.
To obtain a harvest, the variety requires a sunny, wind-protected location; cultivation in a fan shape against a wall is often recommended. Fruits ripen in August or early September and are suitable for fresh consumption or processing.
