Crab apple thrives best in heavy, moist, well-drained soil and areas of scrub.
One of the ancestors of the cultivated apple (of which there are more than 6,000 varieties), it can live to up to 100 years. Mature trees grow to around 10 m in height. They have an irregular, rounded shape and a wide, spreading canopy. With greyish brown, flecked bark, trees can become quite gnarled and twisted, especially when exposed, and the twigs often develop spines.
In spring, the sweetly scented blossom is pollinated by bees and other insects, which develops into small, yellow-green apple-like fruits, around 2-3 cm across.
