Flower spikes are large and compact on stems high above the leaves in June and July. “This spring is the most birds I’ve seen on my property. The plant produces leaves and flower stalks for 5-7 weeks after germination in early spring, then spreads laterally. Infestations can become so dense that they are even capable of suppressing tree growth in floodplain forests. These ecotypes look identical but vary in their growth. : +1 206 685 8755; fax: +1 206 685 2692.

When it escapes from cultivation, it takes over natural ecosystems, altering animal and plant communities and even blocking waterways. In Europe, dominance by reed canarygrass has reduced the conservation value of unmanaged wet grass-lands (Joyce and Wade, 1998). Maygrass is an annual native grass found throughout the southern U.S. An extremely potent smokable form of DMT can be extracted from the reed canary grass (Phalaris arundinacae). Lavergne, S., and J.
