Agrostis nebulosa. Cloud Grass seeds can be direct sown in early spring, any time after the last frost date. In mid-summer, flower spikes emerge to a height of 50cm (20"), with panicles of tiny, cream coloured flowers. The look is diaphanous and airy, and each plant fills in a large volume of garden space. These flower spikes look gorgeous in cut flower arrangements, and they dry particularly well for fall and winter bouquets. This clump forming annual will thrive in sun or partial shade, and it looks sensational in large planting xeriscape systems. Mix it with rocks and taller grasses for a drought-tolerant, wild look. Or plant in larger containers for a striking accent on the patio. In the right setting, this grass will self sow, but it will never become weedy or invasive.
Cloud Grass, a species of bentgrass, forms a diaphanous hazy mist in late summer when its delicate, tiny flowers spread out in all directions. It is useful to know some tips on how to grow cloud grass.
Exposure: Full sun to partial shade
Start seeds indoors 4-6 weeks before planting out. Or direct sow in early spring, when soil is cool and a light frost is still possible. It can also be planted in late autumn.
Just cover the small seeds. At a temperature of 10-12°C (50-55°F) seeds should germinate in 21 to 25 days.
Transplant after last frost into average, well drained soil. Space plants 15-20cm (6-8″) apart. Feed regularly and don’t let the soil become completely dry. Keep an eye on the flowering stage and cut the stems for drying before the seeds set in order to prevent self-sowing. The flower stems are spectacular when dried and will last for months. Cut them and hang them upside-down in a dark, airy place until fully dried.
