Malus 'Coralburst' is a dwarf crab-apple with an upright-spreading form. The main feature of interest is the intense coral-pink fringed white blossom in spring, borne in profusion. Unusually for a crab-apple, these are "semi-double" flowers, with more petals than most crab-apple varieties, creating a dense floral display.
The small fruitlets are yellow/bronze in colour, sometimes russeted, and they remain ("persist") on the tree into late autumn.
Malus 'Coralburst' makes an attractive small garden feature, and is also a good choice for growing in a large patio container. If grown in open ground it is likely to reach a maximum height of less than 2.5m.

Coralburst is a slow-growing dwarf crab-apple, making it a good choice for small spaces.
Although most crab-apples make good pollinators for apple trees, Coralburst is an exception - its semi-double flowers do not produce compatible pollen.
Malus 'Coralburst' was developed by the Cole Nursery of Ohio, USA and released in 1970. It was originally known as 'Coralcole', reflecting the name of the nursery and and the coral colour of the blossom.
Malus 'Coralburst' is unusual in having 8 sets of chromosomes - most apple varieties (and humans) have just 2 sets. It is thought this confers better disease resistance as well as perhaps contributing to the intensity of the blossom.
