Description
Malus ‘Rudolph’ is a striking crab apple, celebrated for its vibrant spring blossom, dramatic foliage, and colourful autumn fruit. In April and May, the tree bursts into bloom with masses of deep rose-pink flowers, opening from bold red buds and attracting pollinators in abundance. As the season progresses, the foliage transitions from a rich bronze-purple to a dark green with a subtle purple sheen, before turning shades of yellow and orange in autumn.
By late summer, ‘Rudolph’ is studded with small, oval, orange-red crab apples that persist well into winter, providing a valuable food source for birds and a splash of colour when the garden is quiet. Its upright, rounded habit makes it ideal as a specimen tree in lawns, mixed borders, or as a feature in smaller gardens.
With reliable performance, strong disease resistance, and year-round interest, ‘Rudolph’ is a fantastic choice for both traditional and contemporary gardens, bringing structure, colour, and wildlife value to the landscape.

Planting:
Space trees 3–4m apart for standards. Plant bare-root or container-grown trees in late autumn to early spring (November–March). Choose a sunny, sheltered site with fertile, well-drained soil. Avoid waterlogged areas and frost pockets. Dig a generous hole, incorporate well-rotted compost, and plant at the same depth as in the nursery. Firm soil, water well, and mulch to retain moisture.

Pruning & Care:
Minimal pruning is needed—remove any dead, damaged, or crossing branches in late winter or early spring. Lightly thin the crown to maintain shape and good airflow.

Fruit Use:
The small, colourful fruits are highly ornamental and excellent for wildlife. While not typically used for jelly, they add winter interest and support garden biodiversity.
