Thamnocalamus crassinodus 'Kew Beauty'
A real gem and one of my favourite bamboos. Billowing masses of exquisite tiny leaves on upright culms that emerge with a blue-grey bloom and turn deep-red with good light. Very tightly clump forming with a height of about 4m. Best with some shade, especially in hot dry areas. Hardy to about -15c. Very beautiful and highly recommended by me.
