FAQ
Frequently Asked Questions
No. Oats (Avena sativa) is a cultivated cereal crop. 'Oat grass' usually refers to wild, perennial grasses that may resemble oats but are different species.
It is not typically grown for human consumption like oats. Some species may be used as forage for animals, but it is not a common food grain.
Tall oat grass (Arrhenatherum elatius) can be invasive in some regions and may be considered a weed in gardens and cultivated land.
Look for grasses with seed heads (panicles) that resemble those of cultivated oats – loose, branching clusters of spikelets. A botanical key is needed for exact species identification.
