A single bamboo plant (BS-0398) called Phai Hia (ไผ่เฮียะ) at Bambusetum Baan Sammi, which Khun Dieter assumed to be Schizostachyum dullooa prior to its flowering, started flowering gregariously in 2023 and produced viable seeds in 2024. Since flowers were first present, this bamboo was confirmed to be Schizostachyum dullooa by Dr. Sarawood Sungkaeo of Kasetsart University, Bangkok. Phai Hia was often misidentified as Cephalostachyum virgatum.
In July and August 2024, flowering branches with seeds could be obtained for free.
On 4 August 2024, we noticed that seeds germinated on the ground and quite a few seedlings developed. These seedlings were also offered in December 2024 and January 2025; they were free. The remaining seedlings were potted and will be offered free, possibly from May 2025 onwards.
