The Story

Plant Bio

Crataegus crus-galli, the Cockspur Hawthorn, is a tough, adaptable North American native tree known for its horizontal branching, dense white flower clusters, and sharp thorns. Crusader ('Cruzam') is a highly desirable cultivar because it is completely thornless, making it a much safer and more versatile landscape plant. It retains the species' attractive qualities, including glossy leaves, white flowers, red fruit, and excellent tolerance of urban conditions.

EarlyLate

Uses & Benefits:

Crusader Hawthorn offers multi-season appeal with its clusters of white spring flowers, glossy dark green summer foliage, good fall color, and bright red winter berries. Its picturesque, horizontal branching provides strong winter structure.

Being thornless, it is an excellent small street tree, well-suited for urban environments due to its high tolerance for pollution, drought, and a wide range of soil types. It can be planted in parks, lawns, and along streets without posing a hazard.

The flowers provide nectar for bees and other pollinators. The dense branches offer nesting sites for birds, and the persistent red fruits are a crucial winter food source for cedar waxwings, robins, and other songbirds.
