Crataegus monogyna Stricta is a tough and durable upright Hawthorn. White flowers are produced in clusters around May time. The dark green leaves are small and turn yellow and orange in the autumn. The Haw fruits are produced following the flower and gradually ripen to a bright red by autumn. It tolerates most soil types that are well drained and coping with extremely cold, exposed conditions. It will even tolerate some exposure to salt laden winds from the coast.
This upright Hawthorn is notable for its extreme columnar shape and ascending branches, which make it a very useful tree in urban environments or gardens where space is limited. It is also a great architectural plant, bringing structure and shape to a planting coupled with year round interest.
Interesting fact: also known as the May tree, due to its flowering period, it is the only British plant named after the month in which it blooms. (thanks to Woodland Trust for this Information)
