Small tree that starts off by growing vertically. The branches grow outwards, later becoming somewhat pendulous so that the shape of the crown becomes more rounded.. The twigs and bark are hairless and dark brown. The young leaves are dark brownish-red. In the summer they turn dark green with a somewhat reddish glow. The flowers, almost 5 cm in size, grow in bundles of 4 to 8 together. In the bud the flowers are brownish-purple but they turn dark purplish-pink when open. The flowers are single. The flowers are followed by numerous elongated orange-yellow fruits, Ø up to 2 cm, that do not remain on the tree for long. 'Rudolph' can be used in parks, gardens and public gardens. Can also be used as an avenue tree because of the small fruit. Shallow roots with a vigorous root system. The tree grows best in nutritious, not too dry soil. Moderately scab-sensitive and extremely winter hardy.
