Description

Golden Crookstem Evergreen Bamboo (Phyllostachys aureosulcata 'Aureocaulis') is a cold hardy running bamboo with a distinctive yellow culms. When planted where direct sun can shine on the culms from the south or west, they often develop a bright magenta highlight for a few weeks in the spring. Established bamboo groves provide a beautiful evergreen privacy screen. It provides ultimate wind protection, noise and traffic screening, and a hedge-like barrier. Bamboo is loved for its tropical lush appearance and a proven performance record in cold climates. It offers the only option for dry shade situations that stays green all winter. Bamboo is a great bird and wildlife shelter. You may also create trails through the bamboo grove for kids to play and built forts. Bamboo shoots 1” diameter plus are edible and quite tasty if harvested when under 6” tall and husked like corn. Timber species can obtain a maximum height of 15 to 20 feet may be achieved in 5 to 10 years. Realistic height of 10-15 feet should be expected in Kansas ( zones 5-6 ). Foliage is evergreen to 0 to 5 degrees F. Canes will defoliate at -5 to -10 degrees F. Canes die to the ground at -10 to -15 degrees. Root system will survive up to -25 to -30 degrees F as a perennial especially if mulched. Every few years a grove will experience complete winterkill: it is strongly advised to cut all dead growth to the ground for aesthetic reasons and and fire prevention. In the year after a complete winter-kill event, new growth will only grow back 1/2 as tall as it was before. It is speculated that after loosing all that foliage and biomass, it is only growing with 1/2 as much energy as before and with loss of potential photosynthesis for months in the spring before it is warm enough for new shoots to emerge. In our trial gardens in Lawrence, KS (zone 6a), all plants were killed to the ground but rhizomes survived with new growth by May. During this arctic blast of February, 2021, lows down to -17 degrees F on Feb 16th, 2021 were recorded. The longevity of this cold blast was also impressive: 10 days on a row with highs of 10-15 degrees F or lower, 8 nights of lows in the single digits and negatives, and 36 strait hours of 0 degrees F and mostly lower. As with any running bamboo, it is important to consider future spread. Spread can be controlled in lawn or forested areas by mowing at least twice a month during the months of May, June, and July and once in September. Another method of spread used mainly in China today is the shallow 12" deep sand-filled trench. Every summer, just run a shovel through the trench a few times to sever any escaping rhizomes. Also use this method for easy propagation. To keep bamboo from spreading into other landscape or formal lawn areas, you must install a continuous border around the grove. 14”-16” deep edging is needed for loamy to clay soils; 18-24” deep border is needed for sandy soils. An effective edging material is high-density polyethylene plastic professional rhizome barrier with lots of information available on proper installation techniques.
