This "yellow-groove bamboo" has been planted at a few locations, especially in suburban situations. It has spread into some adjacent fencerows and roadsides, and may become naturalized. It is generally larger than aurea, In Ky. culms are up to 9 m tall and 4 cm wide (versus usually 5 m and 2 cm); internodes are mostly 30-40 cm (versus 20-30 cm) and less abruptly reduced towards the base, hairy (versus glabrous) and usually dull greenish with a yellowish stripe (versus uniformly yellowish to brownish); culm sheaths are glabrous (versus pubescent at margin of base), usually purplish- and creamy-striped when fresh (versus yellow-green or pale red-brown without distinct stripes); auricles and oral setae are well-developed (versus absent); the ligule is well-developed and purplish (versus only 1-2 mm wide and yellow-green); the blade is purplish or striped like sheaths (versus green with yellow margins). The closely related species, P. bissetii McClure, has also been reported as escaped at a few sites in eastern states (K), but an initial record from Ky. was erroneous (SE). P. bissetii differs from aureosulcata in having hairy culm sheaths with gray-white stripes on upper margins (versus milky-white stripes throughout); also, culms do not have stripes. See Flora of China Vol. 22 for further details. Both species are more hardy than aurea, despite their size, and they are established at many sites in northeastern states (C. Rickel, pers. comm.). Several other species are probably cultivated in Ky. and escapes may be expected. In CLAR, there is a large patch of what may be P. propinqua McClure (below the house on conserved land at end of Old Stone Church Road),
