Notes
In a greenhouse trial failed to germinate after two cycles of cold stratification. When sowed outdoors, very low germination after one cycle of cold stratification (Mabry and Mottl, personal observation); but once established by transplanting self-sows (Mabry, personal observation).
Germinating some sedge species can be complex, and may involve removing the perigynium (bladder like sac that adhers to the hard pericarp of the achene), after-ripening (dry storage), followed by cold stratification, and exposure to light (McGinnis and Meyer 2011). This strategy resulted in successful germination of long-beaked sedge (Balestrieri-Fox, personal observation).
Rhizome course, matted (Mohlenbrock (1999).
