Practical Information

Forage Value
Tall dropseed has only fair forage value. Palatability decreases with maturity. It tends to increase in overgrazed bluestem pastures but it decreases in overgrazed short grass prairie.

Additional Notes

Comments

Tufted or solitary-stemmed. The name "dropseed" alludes to the grain falling readily. Tall dropseed is fairly drought tolerant. The stems and leaves bleach whitish during the winter and wave in the wind like flags.
