Mon La-Ong Fah

หมอนละอองฟ้า
Mon La-Ong Fah · "Sky mist (mon is pillow, the Monthong-family prefix; la-ong is mist; fah is sky). Growers often drop the mon and just say ละอองฟ้า."
Also written: La-Ong Fah · La Ong Fa · Laongfa · Mon Laongfa · ละอองฟ้า

A rare heirloom tied to a single orchard, Suan La-Ong Fah in Nakhon Nayok, which is named after it. Thai sources describe it as sweet, mild-smelling and fine-textured, with flesh that stays firm rather than turning custardy when fully ripe, a low-funk durian for people who want sweetness without the heavy smell. One Western tasting note instead called it sticky and rich, so the texture may vary with ripeness. It is a private seedling selection rather than a registered variety, and is thinly documented, so treat the details as approximate.
