Hosui Pear

Hosui is a real, documented Japanese Asian pear (Pyrus pyrifolia) variety, genuinely popular in both Japan and California. The fruit is large, juicy, sweet, and notably low in acid, with distinctive bronze skin, ripening in early August. The tree is real and documented as extremely vigorous, with a loose, somewhat wild growth habit when left unpruned, typically grown on Pyrus betulaefolia rootstock. It is genuinely, seriously susceptible to fire blight — more so than many other Asian pear varieties — a real, practical consideration growers need to plan around with careful pruning and, where legal and appropriate, antibiotic sprays during bloom. I was not able to find a specific named discoverer or breeder for this variety beyond its general Japanese origin and real popularity. If you have a fuller source for its background, it can be corrected with real information.
