Product Name: Friar Plum (Black Gem Plum)

Description:
The Friar Plum, known in Chinese as "Black Gem Plum" (黑宝石李), is a premium late-season plum variety originating from the United States. Recognized as one of the top ten leading plum varieties in California, this cultivar has been successfully introduced to China since 1984 and is now widely cultivated across multiple provinces.

Appearance:
The fruit is flat-round with a distinctive blackish-purple skin covered in a thick, frost-like white powdery bloom. This striking appearance sets it apart on the shelf and signals freshness. The flesh is cream-white to pale yellow, firm, tender, and juicy.

Flavor:
Exceptionally sweet and refreshing, with a soluble solids content of 13.5%–16.8%. The freestone pit separates easily from the flesh, providing a high edible rate of over 97%.

Size:
Average fruit weight ranges from 72g to 127g, with premium fruit reaching up to 296g under optimal management.

A Storage Superstar:
One of this variety's greatest commercial advantages is its exceptional storage life – 20–30 days at room temperature and 3–4 months under refrigeration (0–5°C). This allows for flexible marketing, extended sales windows, and even holiday-season distribution.

Growing Advantages:
Self-fruitful with low chill requirements, this variety adapts well to diverse growing regions. Good drought and cold resistance make it a robust choice for commercial production. Requires a pollinizer variety (20% ratio) for optimal yields.

Harvest Season:
Mid-August to early September – a late-season gem that extends the fresh plum season and captures premium market demand.
