- Provenance: Seeds received from FY, China, as "Phyllostachys aureosulcata 'Spectabilis', 金镶玉竹 (jīn xiāng yù zhú)", harvested late 2014 (BS-0828), and Nov. 2015 (BS-0828-1).

- Seed weight: 10 g ≈ 420–450 dried spikelets (bract-wrapped seeds).
- Seed viability: Unknown, viability assumed to last at least several months.
- Seed germination: (1) 10 seeds (BS-0828) soaked in clear water for less than 5 h, then laid on moistened tissue paper in transparent breeding box, from 29 May 2015, 34-36 °C daytime highs, diffuse light, 24-25 °C night lows, atmospheric humidity >70%, the first 2 seeds began to germinate visibly on the 5th day after sowing, and 8 seeds germinated by the 15th day. A germination rate of about 80% can be expected (test 150529). (2) Seeds of the new harvest (BS-0828-1) were tested in January 2016 (test 160119), and germination rates were similar.
(1) The seed supplier from China claimed these seeds to be Phyllostachys "aureosulcata 'Spectabilis'". There is no doubt that these seeds belong to the genus Phyllostachys. Whether the seeds, however, belong to the claimed species is unsupported by evidence so far. It is suspected that the seeds will turn out to be true Phyllostachys edulis.
(2) Having checked the characters of a young seedling by August 2017, it became clear that this bamboo is not Phyllostachys aureosulcata but another species of this genus, possibly P. edulis.
