Phyllostachys aureosulcata ‘Spectabilis’
Green Groove Bamboo
Green Grove Bamboo is one of the best all round performers in the large bamboo category. It features glossy light green leaves, with bright yellow and solid green streaked culms.
The culms of Phyllostachys aureosucata ‘Spectabilis’ are generally very upright in growth, but the lower growth will sometimes appear with striking, strongly zig-zagged internodes. If positioned in the right sunlight the golden culms of Spactabilis will become lightly tinged with reddish hues.
The ‘Spectabilis’ cultivar is the hardiest bamboo with a yellow-green striped pattern. The culms of this cultivar take on a bright yellow colour at sheath fall, the time when the new shoots reach their full height in late spring, and are lined with solid green grooves (sulcus). When grown in full-sun the highlight tinge Spectabilis acquires appears in a streaking reddish colour.
Native to East China, the name aureosulcata is derived from Latin meaning ‘golden’ and sulcus meaning ‘furrow’. This species is upright growing, with narrow stature, perfect for use as a tall screen in the garden.
Care & Size Guidance
Phyllostachys aureosulcata requires little to no maintenance, though if required the plant may be thinned out and spent canes can be cut back to the ground level.
This bamboo produces underground rhizomes which aid its spreading, meaning it requires the installation of root barrier to prevent it from becoming invasive.
