CRITIQUE
This was developed many years ago at the Morden Research Station in Manitoba, Canada. Like the other hawthorns we recommend, it has disease and insect resistance, and has year-round interest in the landscape. In late May, clusters of double white fragrant flowers appear, aging to showy pale pink. Medium-sized dark red fruit ripens in late summer and persists that way through winter. In autumn, the green leaves migrate from yellow to orange. The trunk and branches have a distinctive yellow-orange bark and become ‘muscled and twisted’ with age adding another unique characteristic to this tough tree.
