The Okame Cherry tree, was created in England with the goal to create a cherry with the hot pink flowers of Prunus campanulata, and without its sensitivity to cold. This tree blooms earlier than other cherries, and has alternate leaves that turn bronze to bright red and orange in the fall. Despite the selection of this tree, it is susceptible to many different pests and diseases such as leaf spot, die back, leaf curl, powdery mildew, root rot, and fire blight. Potential pests include aphids, scale, borers, leafhoppers, caterpillars, tent caterpillars, and Japanese beetles. It is best grown in moist, moderately fertile, well-drained loam soil in full sun.
