Thailand's signature dessert mango — long, slim, golden-yellow, fibre-free, perfumed; the canonical mango sliced over warm sticky rice with coconut cream in *khao niao mamuang*.
Thai for 'flower water' — *nam* (water) + *dok* (flower) + *mai* (wood/tree). The name describes the cultivar's floral, perfumed sweetness — the ripe pulp tastes 'like the water of flowers'.
The Nam Dok Mai (น้ำดอกไม้) — Thai for "flower water" — is Thailand's signature dessert mango and one of the most exported cultivars in the world. The name is a Thai poetic metaphor for the fruit's perfumed, floral sweetness: ripe pulp is said to taste like the water of flowers. A slimmer, more golden sub-strain called Nam Dok Mai Si Thong (น้ำดอกไม้สีทอง — "golden flower water") was selected in the 1990s and has gradually displaced the older Nam Dok Mai in commercial orchards, particularly for export.
The cultivar's commercial heartland is Thailand's central plain — Chachoengsao, Nakhon Pathom, Ratchaburi and Phichit provinces — where alluvial soils, ample irrigation, and a long growing season let trees produce both an in-season crop (March–June) and induced off-season crops at other times of the year. Thai growers pioneered the chemical induction of off-season mango flowering using paclobutrazol in the 1980s, and Nam Dok Mai was the cultivar that benefited most: a global supply of Thai mangoes is now available year-round, with peak quality and prices in April–May.
Visually, Nam Dok Mai is a slim, oblong, gently curved mango with a small, neat beak — 250–450 g typical, with a thin skin that ripens from green to a clean golden-yellow. The flesh is uniform pale gold (deeper in the Si Thong sub-strain), absolutely fibre-free, and silky enough to slice into neat half-cm cubes for plating. Brix sits 17–22°, with the variety's defining quality being not just sweetness but the floral aroma that gives it its name — somewhere between honey, jasmine, and ripe lychee.
In Thai cuisine, Nam Dok Mai is canonically paired with sticky rice in khao niao mamuang (ข้าวเหนียวมะม่วง) — warm coconut-sweetened glutinous rice topped with chilled mango slices and a drizzle of salty coconut cream. The dish is so dominant in Thai mango culture that it's effectively the national dessert, eaten across the country at hawker stalls, family meals, and high-end dessert restaurants alike. Beyond khao niao mamuang, Nam Dok Mai is the base for Thai mango smoothies, mango sticky rice ice cream, and increasingly for high-end Western patisserie working in Bangkok and Chiang Mai. By value, it is Thailand's top mango export — premium fruit ships under the Nam Dok Mai Si Thong brand to Japan, Korea, China, and the Gulf.
