How to Grow Stipa
Stipa tenuissima
Stipa tenuissima is a fine, wispy grass that catches every breeze, creating a mesmerising flowing effect. Plant in spring in full sun and very well-drained soil, spacing about 40 cm apart. It is evergreen in mild winters, so never cut it back hard — instead, comb out dead material with your fingers in early spring. Stipa is short-lived (3-4 years) but self-seeds prolifically, so you will always have new plants appearing. Excellent in gravel gardens, along path edges, and in containers. The main killer is winter wet, not cold.
Yearly Lifecycle
Care Essentials
No feeding needed. Stipa thrives in poor, well-drained soil. Rich soil produces lank, floppy growth.
Watch For
- Self-seeding (can be prolific)
- Crown rot in wet winters
- Short-lived (replace every 3-4 years)

☀️ Light
Full sun essential
Stipa needs full sun for the best display. In shade it becomes lank and produces few flower heads. At least six hours of direct sun daily.
💧 Watering
Very drought-tolerant, hates wet feet
Once established, stipa rarely needs watering. Overwatering and poor drainage are the main killers. Only water new plantings in their first summer during dry spells.
🌱 Fertilizing
No feeding needed
Stipa thrives in poor, lean soil. Feeding produces soft, floppy growth that loses the characteristic fine texture. Do not add compost or fertiliser.
✂️ Pruning
Comb out dead material in early spring
Never cut back hard — stipa is evergreen and hard cutting kills it. In early spring, run your fingers or a hand rake through the clump to pull out dead strands. Remove any tatty outer growth with scissors.
🍂 Mulching
Gravel mulch only, never organic
A gravel mulch around the crown improves drainage and suits the plant perfectly. Avoid organic mulches which hold moisture against the crown and promote rot.
Growing Tips
Never cut back hard
Stipa is evergreen. Hard cutting kills it. Simply comb out dead strands with your fingers or a hand rake in early spring.
Drainage is everything
Stipa will rot in heavy, wet soil. Add grit at planting time on clay, or grow in gravel gardens and raised beds.
Embrace the self-seeding
Stipa is short-lived but self-seeds freely. Let seedlings establish where they appear for a natural, relaxed look.
Perfect for gravel gardens
The fine texture and drought tolerance make stipa ideal for gravel gardens, Mediterranean schemes, and hot dry borders.
Catch the light
Plant where low sun can backlight the flower heads. The wispy plumes glow golden when lit from behind in the evening.
Pests & Diseases
Pest Aphids
Identification: Small clusters of green or black aphids on flower stems; sticky honeydew
- Blast off with a strong jet of water
- Encourage natural predators like ladybirds and lacewings
- Rarely necessary; tolerate minor infestations
Pest Leatherjackets
Identification: Yellowing patches; grubs found in soil around roots; plants easily pulled from ground
- Apply biological nematode control (Steinernema feltiae) in autumn
- Encourage birds which feed on larvae
- No chemical controls currently available for garden use in the UK
Disease Crown Rot
Symptoms: Plant collapses suddenly; crown is soft and mushy at soil level; foul smell
Treatment: Remove and replace affected plants; improve drainage before replanting
Prevention: Ensure excellent drainage; avoid heavy mulching against the crown; do not overwater
Disease Rust
Symptoms: Small orange-brown pustules on leaf blades; cosmetic damage only in most cases
Treatment: Comb out affected foliage; the plant usually recovers naturally
Prevention: Good air circulation; avoid overcrowding
