regnum-plantae:

Raphiolepsis umbellata, Rosaceae

Currently in bloom, this evergreen shrub native to sunny coastal areas of Korea and Japan is generally known as yeddo hawthorn, but is more closely related to loquat (Eriobotrya) than to the genus Crataegus, and able to hybridise with it. Although the leathery and glossy leaves don’t scream Rosaceae, the flower structure is pretty typical of the family and the blooms are usually white and honey scented, very attractive to pollinators like those of the common hawthorn it is colloquially named after. Just as important to wildlife are the small fruits produced through summer, dark purple when ripe in autumn and made up of a thin layer of flesh over a relatively large seed. The seeds are edible and can be turned to flour, but they are considered a famine food in the plant’s native area so they are far from a common food item. 

I photographed this plant in a heated glasshouse, but it can be hardy to -15°C, enough to be grown outdoors if positioned in a warm, sheltered area, as long as it is provided with a loamy, well-draining soil, consistent moisture and plenty of care.
