Grass that dances in the gentlest breeze. Pony Tails Mexican feather grass is a clump-forming ornamental grass with very thin, thread-like leaves in bright green, growing up to 30 cm long. In summer, the clumps produce fluffy, silvery-beige flower heads that sway with every gust - the plants eventually reach 40–60 cm in total. It is this grass that creates the “angel hair” effect in prairie and gravel gardens.

What makes this variety special
Pony Tails is a compact, uniform-growing variety of Mexican feather grass (in newer taxonomy, Nassella tenuissima). Unlike most ornamental grasses, it produces clearly visible flower spikes in its first year from sowing, so the effect is immediate. The leaves and flower spikes are so delicate that the plant looks like moving mist - hence its popularity in modern, naturalistic plantings.
Mexican feather grass originates from the dry steppes of the Americas, so it prefers full sun and lean, well-drained soil. It tolerates frost down to around -15°C: in warmer regions of Poland and in dry positions, it overwinters without problems; in colder areas, it is often grown as a short-lived perennial or annual - although it usually self-seeds and returns to its place.
Growing step by step
Sowing (March, under cover): sow the seeds in plug trays or pots, covering them with a thin layer of growing medium. At a temperature of 15–20°C, seedlings emerge after 3–4 weeks. Alternatively, you can sow directly outdoors in April-May, once the soil has warmed up.
Pricking out: a single seedling takes a long time to bulk up, so prick out 3–5 plants together into 8 cm pots - this will give you a well-developed plant straight away.
Planting out (May): plant in the final position at 30 × 30 cm spacing, in moderately fertile, well-drained soil and full sun. On heavier soils, it is worth adding gravel or sand.
Care: practically none: water only during prolonged drought, and do not fertilise. Do not cut back the leaves for winter - they protect the centre of the clump. In spring, do not cut it down to the ground like other grasses; instead, comb out the old, dried blades with your fingers or a rake. In colder regions, cover the clumps with conifer branches in autumn.
Uses
Ideal for perennial and prairie borders, gravel gardens and rock gardens, as an edging along paths, and in containers on a sunny terrace. It combines beautifully with woolly sage, coneflower, stonecrop, lavender and catmint - providing them with a soft, gently moving background. Cut flower spikes dry attractively and are suitable for dried bouquets.
Gardener's tip
Mexican feather grass sown in March will produce flower spikes in summer of the same year. Do not remove the drying flower spikes in autumn - they look attractive, protect the plant in winter and release seeds from which young clumps will grow in spring, ready to be transplanted to your chosen locations.
