Pasqueflower is a low-growing European perennial in the buttercup family, native to calcareous grasslands across central and northern Europe. It produces silky, cup-shaped purple to violet flowers in early to mid spring, often pushing through late frosts, followed by feathery, silvery seed heads that persist well into summer. It suits rock gardens, raised beds, and dry sunny slopes where drainage is sharp and soil leans alkaline.
The plant demands gritty, well-drained, alkaline soil and tolerates drought once established, but crowns rot quickly in heavy or waterlogged ground. It resents disturbance after establishment, so site it permanently from the start. Seed viability drops sharply within weeks of ripening — sow fresh seed immediately after collection for reliable germination. A thin grit mulch around the crown helps prevent collar rot in wetter climates.
All parts contain protoanemonin, which causes skin irritation on contact and is toxic if ingested fresh. Dried Pulsatilla preparations have a long documented history in European herbal and homeopathic medicine, associated with menstrual pain, headache, eye inflammation, and earache.
Crown Rot
Lower leaves yellow and wilt; the base of the rosette turns brown and soft, sometimes with white fungal threads at the soil line. Plants collapse in wet conditions.
Remove and destroy affected plants. Improve drainage and avoid overhead watering. Do not mulch directly against the crown. Space plants for airflow and avoid replanting in the same wet spot.
Root rot
Plants wilt, yellow, and stunt even in moist soil; lower stems and roots turn brown, soft, and mushy and the plant may collapse. Most common in heavy, wet, or poorly drained ground.
Improve drainage and stop overwatering, and never plant too deep. Lift and destroy badly affected plants along with the soil around the roots. Grow in raised or free-draining beds to prevent it returning.
Damping Off
Seedlings collapse at the soil line with thin, water-soaked stems; seeds may fail to emerge or rot before sprouting.
Sow in well-draining mix, avoid overwatering, and ensure good airflow. Remove affected seedlings and let the surface dry between waterings.
Botrytis (grey mould)
Grey fuzzy mould on petals and stems, worst in cool wet conditions.
Remove affected parts immediately. Improve air circulation. Avoid overhead watering. Apply copper fungicide if severe.
Foliar Nematode
Angular brown or black patches on leaves, bounded by leaf veins, starting on lower foliage and moving upward. Affected leaves wither but stay attached.
Remove and destroy infected leaves and surrounding debris. Avoid overhead watering and wetting foliage. Space plants for airflow and do not compost affected material. Severely infested plants should be dug out and discarded.
