Coralburst Crabapple

Malus 'Coralcole'

The Story

Plant Bio

Crabapple trees are small to medium-sized deciduous trees highly valued for their spectacular spring floral display. They also offer attractive foliage, and often colorful, persistent autumn fruit that provides winter interest.

Coralburst® ('Coralcole') is a true genetic dwarf crabapple, forming a dense, compact, rounded crown that requires no pruning to maintain its shape. It is renowned for its beautiful coral-pink buds that open to fragrant, semi-double, rose-pink flowers, followed by sparse, bronze-red fruit.

Uses & Benefits:

Coralburst® is a jewel in the landscape, offering a breathtaking spring display of coral and pink flowers on a perfectly rounded, dwarf form. Its neat, formal habit makes it an outstanding specimen for small spaces, courtyards, and entryways where a full-sized tree would be overwhelming. It provides a strong architectural element year-round.

Its genetic dwarfism means it is exceptionally low-maintenance, requiring virtually no pruning to keep its tidy shape. This makes it an ideal 'plant-and-forget' specimen tree for busy homeowners or those with limited garden space. It is also well-suited for growing in large, decorative containers.

The flowers of crabapple trees are an important early-season pollen and nectar source for bees and other pollinators, crucial for fruit set in nearby orchards and gardens. While the fruit of 'Coralcole' is sparse, the fruit of many other crabapple varieties persists into winter, providing a vital food source for birds like cedar waxwings and robins.
