How it is used
Food
Rating: 2
Seed - cooked. Rather small. The seed ripens in the latter half of summer and, when harvested and dried, can store for several years. It has a floury texture and a mild, somewhat creamy flavour. It can be used as a staple food crop in either savoury or sweet dishes. The seed can be cooked whole, though it is more commonly ground into a flour and used as a cereal in all the ways that oats are used, especially as a porridge but also to make biscuits, sourdough bread etc. The seed can also be sprouted and eaten raw or cooked in salads, stews etc. The roasted seed is a coffee substitute.
Seed: includes nuts, cereals, peas and beans.
Coffee: the various substitutes that can be used instead of coffee.

The straw has a wide range of uses such as for bio-mass, fibre, mulch, paper-making and thatching. Some caution is advised in its use as a mulch since oat straw can infest strawberries with stem and bulb eelworm.
Fibre: Used for making cloth, rope, paper etc.
Mulch: Used for covering the ground to conserve the nutrients in the soil.
Paper: Related to the entry for Fibre, these plants have been specifically mentioned for paper making.
Thatching: Used for making thatched roofs.
How it is grown
Succeeds in any moderately fertile soil in full sun. A triploid species, it is rarely cultivated for its edible seed. Oats are in general easily grown plants but, especially when grown on a small scale, the seed is often completely eaten out by birds. Some sort of netting seems to be the best answer on a garden scale.
Propagating it: Seed - sow in situ in early spring or in the autumn. Only just cover the seed. Germination should take place within 2 weeks.
Best place to grow: Cultivated Beds;
Habit: Annual
Hardiness: 4-8
Growth: Fast
Soil: Light (sandy), medium
Shade: No shade
Moisture: Dry, moist
Things to keep in mind
This plant can be weedy or invasive. Avena barbata has spread widely in North America where it has been reported to displace native grass species. It is recorded as a noxious weed in the USA. In Australia, it outcompetes native grasses and forms a fibrous root system. It can also alter the fire regime of an area.
