Crataegus laevigata Mutabilis Ravnholdt - Hawthorn

The Crataegus laevigata 'Mutabilis Ravnholdt' is a selection from the smooth hawthorn, also known as the two-style hawthorn or spiny hawthorn, a shrub species found in northern France. This form is sometimes referred to simply as 'Mutabilis'. Its flowering starts with a pale pink color and then turns to a grayish white. Its miniature rose-like flowers are double. They give way to small dark red fruits on a yellow autumn foliage. Aside from the flower color, 'Mutabilis' bears a strong resemblance to 'Paul's Scarlet'.

The Crataegus laevigata belongs to the Rosaceae family, just like the wild rose and plum. Although quite common in France, it is less so than its close relative Crataegus monogyna, the white hawthorn. 'Mutabilis Ravnholdt' forms a small tree or a large hardy bush that can reach 5 to 7 m (16 to 23ft) in height at maturity and 3 to 4 m (10 to 13ft) in width. Its habit is generally rounded, well-branched, with a wide crown. The stump can sucker, allowing it to spread in width. Its branches are equipped with extremely strong long thorns. They bear deciduous, alternate leaves measuring about 5 cm (2in) in length, ovate and lobed, of a shiny dark green color, turning yellow in autumn before falling. In early May, double flowers measuring about 2 cm (1in) in diameter grow in small tight clusters. They are pale pink and gradually fade to a grayish white. In September, birds feast on its red pear-shaped fruits, 2 cm (1in) in diameter, called haws. They are not edible.

The Crataegus laevigata 'Mutabilis Ravnholdt' is easily grown in well-drained and not overly dry soil, in a sunny or semi-shaded location. Not demanding, it will be satisfied with pruning in February to maintain balance. Plant it in a large bed, with shrubs with small flowers such as Deutzia and Kolkwitzia. Add lower shrubs and evergreen conifers. Also, plant it in a large hedge, wild or defensive. Appreciated by many insects, birds, and small mammals, it is the ultimate food plant. Take advantage of this to create an ecological hedge with other shrubs that provide shelter and food: Prunus spinosa, Sambucus nigra, and Viburnum opulus.
