In areas where the average winter minimum temperature is above -15°C (5°F), it may grow to a maximum height of {{convert|14|m|ft|abbr=off|sp=us}} with a diameter of {{convert|6.5|cm|in|abbr=on}}.{{cite web| url= http://www.lewisbamboo.com/yellowgr.html| title= Lewis Bamboo - Phyllostachys aureosulcata (Yellow Groove Bamboo)| accessdate= 2011-05-24}} The typical form of this species has dark green culms with a yellow groove.

Distribution
This bamboo grows in areas ranging from subtropical to warm temperate and tolerates low winter temperatures better than most bamboos, being one of the hardiest bamboos in the genus Phyllostachys.{{cite web|url=http://www.needmorebamboo.com/hardiness.html |title=Hardiness ratings |accessdate=2012-06-19 |url-status=dead |archiveurl=https://web.archive.org/web/20120619041642/http://www.needmorebamboo.com/hardiness.html |archivedate=June 19, 2012 }} Outside its natural range and areas where the coldest month has mean temperatures of below {{convert|-4|°C|°F|abbr=on}}, the leaves of P. aureosulcata may not be evergreen and may turn beige and fall off.{{Citation needed|reason=source needed for this sentence|date=May 2014}}
In areas with severely cold winters (USDA hardiness zone 5 or colder) in the northern parts of the US, northern Asia, and northern Europe, all growth above ground will die back every winter if temperatures remain below {{convert|-18|°C|°F|abbr=on}} for extended periods {{Citation needed|reason=source needed for this phrase|date=May 2014}} but will regrow in the spring to {{convert|1.8|to|2.4|m|ft|abbr=off|sp=us}} tall.
Phyllostachys aureosulcata is a popular bamboo in the warmer areas of the United States, Europe, Asia, and parts of Australia. In China it is cultivated and found in Beijing and the provinces Henan, Jiangsu and Zhejiang.
Name
The culm coloration inspires this bamboo's common name of "yellow groove bamboo" and botanical name of aureosulcata.{{cite book| title= CRC World Dictionary of Grasses| author= Umberto Quattrocchi| year= 2006| page= 1705| publisher= CRC| isbn= 978-0-8493-1303-5}} The all-green cultivar 'Alata' is also known as "crookstem bamboo" due to its characteristic culm bends common to this species.
Usage
Cultivated mainly as an ornamental, this species is also among the best for edible shoot production, being free of acrid flavor even when raw. An aggressive spreader, its dense upright growth makes a good hedge or privacy screen.
