This Double Flowering Almond has never been a common ornamental shrub in The Midwest to the Atlantic Coast in the US. A few nurseries that I worked at in the Chicago, IL, area in the 1980's & 1990's would sell a few potted plants, maybe bringing in 10 or 20 plants to the nursery yard. One might still find a few plants in a few landscapes in a few towns; I have not seen one for years. It was commonly listed in older nursery catalogs and magazines, and a few may still offer this. This 'Multiplex" is the double flowering cultivar of the Flowering Almond (Prunus triloba) that was offered, and it is sterile like most double flowering plants and does not bear fruit.. The regular species of Prunus triloba (Flowering Almond) does have single flowers and can bear 1/2 inch wide rounded red fruits, but is not grown in the US, unless some arboretum has a few. It is not a really great landscape plant. Its big feature is the mass of pink double flowers in April, and I am not sure if anything in the US pollinates it. It does have good-looking cherry-like bark to see in winter.
