The national flower: Ratchaphruek
- Ratchaphruek (ราชพฤกษ์), the golden shower tree (Cassia fistula), is Thailand's national flower — cascading chains of brilliant yellow blossoms that light up the country, especially around the hot season into the rains;
- The color matters: its golden-yellow is deeply significant — yellow is associated with Monday (the birth-day of the late King Bhumibol Adulyadej) and with Buddhism and royalty, giving the flower profound national resonance;
- A national symbol: Ratchaphruek is one of Thailand's three national symbols (alongside the elephant and the sala Thai pavilion), representing unity and Thai identity;
- Where you'll see it: planted along roads, in parks and gardens across the country — a spectacular sight when the whole tree turns to gold (when it blooms).
Flowers and royalty
- Royal Thailand and flowers are closely intertwined — flowers feature in ceremony, and the Royal Flora Ratchaphruek (a world-class horticultural expo held in Chiang Mai) was named in the King's honor;
- Color-day symbolism: Thai culture associates each day of the week with a color, and flowers of the corresponding hue carry meaning — part of the rich symbolism of Thai flowers;
- The lotus holds its own sacred and quasi-royal status in Buddhist Thailand (the lotus).
A country in bloom
Beyond the official national flower, Thailand's warm climate makes it one of the most flower-rich countries on earth — orchids, jasmine, lotus and countless tropical blooms are woven through everyday life, faith and celebration. This site is a tour of them all.
