Crataegus crus-galli var. intermis or Thornless cockspur hawthorn, is a native cultivar to Ontario and ranges from Quebec to North Carolina and Kansas. This thornless, small flowering tree is known for its attractive spring blooms and persistent red fruit. It thrives in well-drained soils with full sun but can tolerate light shade, mild drought, and urban pollution, making it versatile for landscaping. Although its flowers have an unpleasant fragrance, its adaptability and thornless branches make it an excellent choice for parks and open woodlands.
