Holodiscus (syn. Sericotheca) is a genus of flowering plants in the family Rosaceae, native to the Americas, from southwestern British Columbia, Canada and the western United States south to Bolivia.[2]

The species are deciduous shrubs, growing to 1–7 metres (3.3–23.0 ft) tall.


Seven to ten species are accepted by different authors, including:


The position of the genus Holodiscus in the family Rosaceae has changed over the last century as more detailed studies have been carried out. It has been place in subfamily Maloideae, but recent molecular evidence places all of (the former) subfamily Maloideae inside the subfamily Amygdaloideae.[1]
