I have planted three Prunus 'Hally Jolivette' trees along the stairway from the lower terrace to the woodland garden to create a small groove. Two of these trees frame a view of a Cercidiphyllum japonicum tree as seen through the French doors of our garden room. Prunus 'Hally Jolivette', which has pinkish-white double flowers opening from pink buds, is a quick-growing round shrubby tree to about 15 feet high and wide. The delicate dark green leaves with serrated edges are also very ornamental and contrast the round leaves of the Katsura tree nicely.
Prunus 'Hally Jolivette' is the result of a cross of Prunus subhirtella x Prunus yedoensis backcrossed again with Prunus subhirtella by Dr. Karl Sax of the Arnold Arboretum in 1940. It is on more than one "top ten small trees" list that I have seen over the years. My trees are planted on a very sandy and steep slope which has sharp drainage in full sun and seem quite happy. The flowers opened today and have created dense white cloud which is currently the star in the garden. Prunus 'Hally Jolivette' is a distinctive, yet easy, tree that would be an terrific addition to even the smallest garden.
