Trembling Aspen
Tall Manna Grass

Trembling Aspen is a hardy, fast-growing tree. It is known for its unique "trembling" leaf movement and beautiful bark that whitens with age.

This native shade tree tolerates a range of growing conditions and requires little maintenance.

Manna Grass and other waterside plants are an excellent way to prevent erosion and provide habitat and forage for animals. The difference is that Manna Grass looks better doing it! With distinctive purple grains at the top of its stalks, Manna Grass adds a splash of color to the waterside that most other aquatics can't offer.

Manna Grass is good for returning disturbed sites to nature and provides nourishment to many animals, except for cattle who find it toxic.
