Chasmanthium latifolium
Although tolerant of quite shady conditions, this grass is non-flopping and flowers most profusely in full sun. Forms tight crowns from which many stems arise clothed in bright green bamboo-like leaves retaining colour even in dry shade. The spikelets appear in late summer and fall in terminal open panicles. They look pressed flat as stamp consisting of nicely arranged fish-like scales. As spikelets age, they turn from green to reddish-brown in late fall.
Native to eastern North America. The flat seed heads are distinctive and valuable for arrangements. Suitable for shade to sun making it versatile. The bamboo-like leaves are attractive. Tolerates dry shade remarkably well. The seed heads persist into winter. Combines well with woodland plants. May self-seed moderately in appropriate conditions.
