Avena grasses can be either hardy annuals or hardy perennials.
They tend to flower at the height of summer and are commonly known as Common Oat, Wild Oat, Cat Plant and Animated Oat.
Plants can reach heights of between one and four feet (30 to 120 cm).
They have blue leaves and blooms are usually green spikelets.
Avena should be used as an emphasis plant for the garden, and can also be grown in containers.

The Avena genus contains up to 15 species and is often known as the Oats genus, it belongs to the Poaceae family of true grasses. Members of this widespread family are native to Europe, Asia and parts of North Africa.
Oats can be grown in the garden both as a food source or more commonly in the garden, as a decorative grass. Some of the Avena species that are cultivated as a food source are as follows:
Avena sativa: Common Oat; Cat Grass
Avena abyssinica: Ethiopian Oat
Avena nuda: Hulless Oat
Avena strigosa: Bristle Oat
Species of Avena that are commonly grown in gardens as ornamental grasses include A. Sativa from above and:
Avena fatua: Common Wild Oat
Avena barbata: Slender Wild Oat
Avena sterilis: Winter Wild Oat; Animated Oat
Avena brevis: Short Oat
Avena occidentalis: Western Oat
As a member of the 10,000 species strong grass family (Poaceae) Avena species are closely related to species such as Barley (Hordeum), Maize (Zea), Rice (Oryza), Wheat (Triticum), Calamagrotis, Festuca, Melica and Needlegrass (Stipa).
Did you know that the term 'corn' means 'local cereal grain'? Therefore the use of the word corn means different thing in different countries. In the country of Scotland, when someone refers to corn they mean Oats.
Did you know; number two: common oats (Avena sativa) are also known as 'Cat Grass' because cats love to eat them; they contain many nutrients that are missing from the canine diet. Many people grow this plant in containers indoors especially for their house cats.
Many of the wild oats are considered to be an invasive species in the USA as they love to grow in farmers fields and are able to out-compete many native grasses.
Common Names: Common Oat, Wild Oat, Cat Plant, Cat Grass. Animated Oat.
Life Cycle: Hardy annual. Hardy perennial.
Height: 12 to 40 Inches (30 to 100 cm).
Native: Europe, West Asia, North-west Africa.
Growing Region: Annuals: zones 3 to 9. Perennials: zones 4 to 10.
Flower Details: Green. Inconspicuous. Panicles.
Sow Outdoors: 1/4 inch (6 mm). First two months of spring. Germination time: one to three weeks. Temperature 60°F (16°C). Spacing: Annuals 12 Inches (30 cm); Perennials 18 inches (45 cm). Seven or eight weeks in advance.
Sow Indoors: No.
Requirements: Full sunlight. Soil pH 6 to 7. Good drainage. Poor and average soils. Plants are drought tolerant but perform best if watered regularly.
Avena seeds should be grown outdoors, sow the seeds of oats at a depth of 6 mm at the beginning to middle of spring.
The seedlings of oats can also be purchased; annual varieties should be planted in the early spring, whereas perennial varieties can be planted either in the early spring or in autumn.
Depending on the variety Avena seedlings should be planted 25 to 30 cm (10 to 12 inches) apart (small) or 45 to 60 (15 to 24 inches) cm apart (larger varieties of oat).
They should be planted in an area that receives full sunlight in a dry soil with a pH of 6 to 7.5.
Avena species are easy to look after, they should be regularly watered (although they are pretty drought tolerant) for best growth, and can be left alone all year round.
Dried Avena make a very attractive plant to use in flower arrangements. Cut off the seed heads (and as much stem as you desire) once the seeds have developed. Dry upright indoors, this will produce dried oats that appear to droop naturally.
Avena sativa: Common Oat
This annual species is a well known food crop, especially in Scotland where it is used to make porridge. Oat Plants range in height from two to three feet (30 to 90 cm) and should be grown in full sunlight.
Sow Avena sativa seeds at a depth of ¼ inch (6 mm) in early spring. The plants have green inconspicuous blooms and form spikelets. Although a food plant in the garden they are usually used for ornamental purposes. For best results water regularly. These plants can be grown as part of a grouping or as a container plant.
Avena fatua: Common Wild Oat; Cat Grass
This annual species is native to Eurasia, In the Americas it is considered weedy and invasive by many states, as it is able to grow strongly and out compete crops grown on prairies.
Avena fatua Plants are usually about two feet (60 cm) in height but can reach up to four feet (1.2 M). They have tall upright hollow stems that bear panicle inflorescence's that form spikelets.
For best results, grow plants in areas of full sunlight, they will bloom (inconspicuously) in the Summer. Water regularly for optimal results.
To prevent spread be sure to deadhead before they have chance to set seed.
