Summary

Crataegus submollis, commonly known as Northern Downy Hawthorn, is a deciduous tree or large shrub native to open woodlands and forest edges in the Northern USA and Southeastern Canada. It typically grows to a height of about 7 meters and has a rounded crown. The Northern Downy Hawthorn is notable for its clusters of fragrant flowers that bloom in late spring, ranging in color from white to pink, with a rare occurrence of purple. The flowers are followed by large, bright red fruits, or haws, which persist into winter and provide food for wildlife. The plant’s thorns, which can reach up to 7 cm in length, are a distinctive feature, offering protection to birds that nest within its branches.

This species is valued for its ornamental qualities, including its showy flowers and attractive fruit. It is used in urban and rural plantings, often as a specimen or in mixed shrub borders. The Northern Downy Hawthorn is adaptable to a range of soil types, from clay to loam, and prefers well-drained conditions. It is tolerant of both full sun and partial shade. While it can handle medium to high water availability, it is also somewhat drought-tolerant once established. Gardeners should be aware that this hawthorn can be susceptible to leaf blight and fire blight, and its thorns can make maintenance tasks challenging. It is not typically invasive when grown outside its native range, but care should be taken to prevent the spread of diseases to other susceptible plants.CC BY-SA 4.0
