Plant Profile: Exochorda 'Blizzard' PP23,329

In the designation Exochorda 'Blizzard' PP23,329, the term Exochorda refers to a genus of deciduous shrubs native to China and Korea, commonly referred to as Pearlbush. The 'Blizzard' variety is a hybrid that results from the crossbreeding of E. serratifolia, E. racemosa, and E. korolkowii. The designation PP23,329 indicates the United States Plant Patent granted for this particular hybrid.

Pearlbush is primarily cultivated for its ornamental value, showcasing stunning white flowers and a pleasing growth habit. The flower buds, which resemble white pearls, contribute to its common name. This resilient plant bursts forth with pearl-like buds and delicate petals at the onset of spring, rivaling the beauty of Forsythia. The 'Blizzard' hybrid is characterized by its upright to mounded shape, reaching a mature height and width of 3 to 4 feet. This refined structure sets it apart from other Pearlbush hybrids, such as 'The Bride', which can appear more chaotic and cascading. Additionally, 'Blizzard' is exceptionally prolific, producing flowers that can be twice the size of those found on other Pearlbush varieties.

This shrub thrives in average, medium-moisture, well-drained soils, favoring acidic, organically rich loams. Once established, it demonstrates good tolerance to drought and heat. Since 'Blizzard' blooms on old wood, it is advisable to wait until after flowering to prune. The plant typically flowers in early spring, providing a valuable food source for insects.

Regarding pests and diseases, 'Blizzard' is not known to suffer from significant insect or disease issues. While it is classified as invasive in certain states, it is not currently considered invasive in North Carolina.
