Overview

Hordeum intermedium, commonly known as intermediate barley, is an annual graminoid that thrives in a wide range of countries including Afghanistan, Albania, Algeria, Bulgaria, and extends across regions such as the Mediterranean, Asia Minor, and Central Asia. This plant is native to diverse habitats within these areas, making it adaptable to various environmental conditions. Intermediate barley is primarily edible, with its seeds being harvested for consumption. The seeds can be dried and ground into flour or used whole in various dishes, providing a nutritious grain alternative. Standing at approximately 1 meter tall, this plant prefers moist conditions but can grow in light (sandy), medium, or heavy (clay) soils, thriving within a pH range of 7 to 7.5. This annual graminoid is known for its adaptability and presence across its native range, making it a notable species in the Poaceae family. It requires full sun or partial shade for optimal growth and benefits from consistent moisture during its growing season, especially in heavier soils. Intermediate barley can be propagated by seed and has been introduced to regions such as California, Canary Islands, Chile Central, Connecticut, Great Britain, Idaho, Montana, Nevada, New York, Oregon, Pennsylvania, South Australia, Utah, Washington, among others. While intermediate barley is primarily valued for its edible seeds, it also serves utility in biomass production and textiles. Its introduction into new areas highlights its versatility and potential as a crop adaptable to diverse climates and soil types. However, caution should be exercised when handling or consuming this plant, given the conservative nature of its medicinal properties.

How to grow Hordeum intermedium for the first time

8steps

This guide will help you grow Hordeum intermedium, a beginner-friendly annual grass.

  1. 1

    What you'll need

    Seeds of Hordeum intermedium and containers or garden space with well-draining soil.

  2. 2

    Best time to plant

    Plant in spring after the last frost, when temperatures are mild.

  3. 3

    Soil and container prep

    Ensure your soil is light (sandy), medium, or heavy (clay) with a pH of 7–7.5. Containers should be at least 30 cm deep.

  4. 4

    Sowing or transplanting

    Direct sow seeds 1-2 cm deep and 15-20 cm apart in rows. Alternatively, start indoors 4 weeks before planting outside.

  5. 5

    First two weeks

    Keep the soil moist but not waterlogged during germination. Thin seedlings to 15-20 cm apart once they have several leaves.

  6. 6

    Ongoing care

    Water regularly, especially in dry periods, and mulch to retain moisture. Fertilize lightly with compost if needed.

  7. 7

    Harvest or pruning

    Cut the seed heads when they turn brown and dry out, usually after 90-120 days from planting.

  8. 8

    Common mistakes

    Overwatering, sowing too deep, neglecting to thin seedlings, using incorrect soil pH, and not providing enough light for indoor starts.
