In addition, Jacobson states that, “at present, based upon leaf characteristics alone” some 10 named clones of purpleleaf plums, including ‘Thundercloud’, are “veritably indistinguishable”. Furthermore comparing catalog descriptions of ‘Thundercloud’ and exanimating trees so named, it is obvious that more than one clone has been marketed under this name. Prune only in spring and early summer, to reduce the risk of disease. This beautiful tree can be left to develop naturally, or trimmed for shorter, denser growth. At the same time the dark purple leaves begin to appear adding depth and texture to the scene. It has beautiful spring time blooms of pale pink that seem to open all at once among the branches.
It will grow from zone 5 to 9, and in any well-drained soil. The ‘Thundercloud’ plum - Prunus cerasifera 'Thundercloud' - is a cultivar of the ornamental flowering plum. The early history of ‘Thundercloud’, now written as a single word, is incomplete and the name was not widely used in the 1920s and 30s. Plant the Thundercloud Purple Leaf Plum in a sunny spot, as shade can cause the leaves to green and reduce flowering. Arthur Lee Jacobson in his monograph, Pupleleaf Plums (1992), reasons that we can’t be sure that it is the “same clone that in recent decades has become the most widely planted purpleleaf plum in North America”. In 1919 Luther Burbank, the innovative and renowned plant breeder of Santa Rosa, California, named a purpleleaf plum he selected as ‘Thunder Cloud’. Prune after flowering to keep trees vigorous. Often does not set a crop of fruit (hopefully!). It produces fragrant, five-petaled pale pink to white flowers in the spring that are roughly an inch across, which then turn to small fruits. It’s a relatively small tree with a rounded growth habit. Coppery-purple foliage through growing season. The purpleleaf plum tree ( Prunus cerasifera ), also known as the cherry plum, is a popular flowering specimen tree for home landscapes. It bears simple, 2-4 long elliptically shaped leaves which are arranged alternately on the shoots. Morphology: This deciduous garden tree grows to height and width of 25’. Flowers a few days later than 'Atropurpurea'. Thundercloud' flowering plum is grown for its red foliage which is borne on a fast growing and upright-spreading tree. Single pale pink to white flowers, appear before leaves.
Flowers a few days later than 'Atropurpurea'. Deciduous tree, small, 15-20 ft (4.5-6 m), similar width, shrubby, twiggy and rounded. Prunus cerisifera Thundercloud, or Thundercloud purple-leaf plum, is a popular ornamental landscape tree in western Oregon and temperate climates. Thundercloud Plum Pronunciation: PROO-nus ser-as-IF-er-a Family: Rosaceae Genus: Prunus Type: Broadleaf Native to (or naturalized in) Oregon: No Deciduous tree, small, 15-20 ft (4.5-6 m), similar width, shrubby, twiggy and rounded.
