Key Facts
- Native perennial of western North America
- Small spring flowering herb with fernlike leaves
- Nodding pink to white heart shaped flowers with a long spur
- Prefers well drained rocky or sandy soils
- Typically found in alpine and subalpine meadows and open slopes
- Attracts early spring pollinators such as bees
- Propagated by seed and by dividing established clumps
- Contains alkaloids and is considered poisonous if eaten
Steer’s Head is a low native perennial from western North America that offers delicate fernlike foliage and nodding heart shaped blooms in spring. Its small size and preference for rocky, well drained soil make it a good choice for rock gardens and cool, naturalized pockets where moisture is limited.
Identification
Plants stand only 2 to 8 inches tall with finely divided, fernlike leaves. Flowers are nodding, pink to white and heart shaped with a long backward spur, giving the common name. Clumps typically spread 6 to 12 inches across as small colonies rather than aggressive mats.
Where to grow and best uses
Fits rock gardens, alpine troughs and open slopes that mimic its native subalpine meadows. Use as a foreground groundcover in cool, sunny sites or a part shade planting at lower, warmer elevations. Avoid heavy clay and waterlogged beds where crowns will rot.
Planting and timing
Sow fresh seed or after cold stratification and plant clumps into gritty, well drained soil. Space plants roughly 6 to 12 inches apart to allow natural clump expansion. Exact sowing dates vary by climate, so match planting to the local cool season and soil conditions.
Soil and light
Prefers well drained rocky or sandy soils with neutral to slightly acidic pH and low fertility. It performs best in full sun in cool sites or part shade where summers are warmer. Provide a cool microsite in lower elevation gardens to maintain vigor.
Watering and general care
Keep plants on the dry side and avoid standing water. Poor drainage leads to crown and root rot while overly moist conditions reduce vigor. Mulch sparingly to maintain drainage and water only during extended dry spells in hot weather.
After flowering and maintenance
After bloom, allow the plant to rest without disturbance and reduce supplemental water as growth slows. Divide established clumps gently when dormant to increase stock or rejuvenate older patches. Removing spent flower stalks limits self seeding if you want tighter control.
Propagation and spread control
Propagate by seed and by dividing established clumps. Seed and gradual clump expansion form small colonies but the plant is not aggressively spreading. Remove seed heads to limit self seeding and avoid disturbing roots when dividing to prevent loss of plants.
Toxicity
Contains alkaloids and is considered poisonous if ingested. Keep away from children and pets that chew plants and consult poison control for exposure concerns. Handle plants with care and do not use as an edible species.
Frequently asked questions
- How fast does Steer’s Head grow?
- Growth is slow to moderate. Plants remain low and expand gradually by clump division and seed over several seasons.
- When does Steer’s Head bloom?
- Blooms in spring, generally March through June in the northern hemisphere, with timing shifting later at higher elevations.
- Is Steer’s Head hardy where I live?
- It is generally suitable for USDA zones 4 to 8 depending on site and elevation. Cooler microsites help in warmer zones.
- How do I propagate it?
- Propagate by seed or by dividing established clumps when dormant. Sow fresh seed or after cold stratification for best germination.
- Is Steer’s Head poisonous?
- Yes. The species contains alkaloids and is considered poisonous if eaten. Avoid ingestion by people and pets.
