Prunus subhirtella- Rosebud Cherry
Trunk and bark of winter cherry (Prunus subhirtella 'Autumnalis'). Also known as the autumn-flowering or rosebud cherry.
Description
General: A flowering deciduous tree growing 20 to 40’ with a spread of 15 to 30.’
Leaves: Alternate, simple and ovate, 1 to 4.” Dark green with a yellow to orange red fall color.
Bark: Shiny and gray brown.
Flowers: White to pink to dark pink depending on cultivar. Single, semi-double or double.
Fruit: Oval, rounded 1/3” across (pea sized) and red, maturing to shiny black later in the summer.
Attributes: Useful as a specimen or in groupings.
Culture
Hardiness: Zones 4-8.
Growing Conditions: Prefers moist, well drained, acid loam in full sun to part shade.
Maintenance: Cherries are susceptible to a number of insect and disease issues, and are usually relatively short lived. Subhirtella, however, is relatively long lived (30 to 50 years) and more heat and stress tolerant than many other cultivars. Subhirtella also have good disease resistance, but are still susceptible to, leaf spot, powdery mildew, fireblight, aphids, scale, borers and Japanese beetles.
Transplanting: Easily transplanted.
Our Experience
Experience at Great Hill
On Great hill we feature a row of Prunus x subhirtella ‘Rosy Cloud’ in our Japanese garden, as well as multiple Prunus x subhirtella ‘Autmunalis’ and Prunus x subhirtella ‘Pendula’. Their early spring color is a great show, but it does come at the expense of regular IPM maintenance in the form of spraying to cut down on instances of disease and insect infestation.
