Malus 'Crimson Knight' (Crab Apple) is a striking ornamental deciduous tree valued for its dramatic seasonal colour and elegant upright form. In spring, it produces an abundant display of deep pink to crimson flowers, creating an eye-catching feature in the garden. Its dark purplish foliage provides strong contrast through the warmer months, while small ornamental red to reddish-purple crab apples develop after flowering and can persist into the cooler season.
A superb choice as a feature tree, Malus 'Crimson Knight' brings interest across multiple seasons without requiring extensive maintenance once established. Its manageable size makes it suitable for residential gardens, lawns, pathways and landscape plantings, while its flowers provide valuable seasonal interest for pollinators and its fruit can attract birds. With full sun and well-drained soil, this distinctive Crab Apple is an excellent choice for adding colour, structure and year-round ornamental appeal.
