Another rare discovery in NE Thailand. This cultivar looks identical in form to the standard T.siamensis that grows throughout SE Asia, however, the culms are yellow/gold with green vertical stripes. Finding a clone of this species with striated culms is the product of the relentlessness of Thoop Nakasen, in Thailand.
It was sent to USDA quarantine and released in September 2018.
