Description
Pulsatilla Alpina Subsp. Alpina, commonly known as the Alpine Pasque Flower, is a perennial herbaceous plant that belongs to the Ranunculaceae family. It is native to the mountainous regions of central and southern Europe, where it thrives in rocky and gravelly soils. This plant grows up to 10-25 cm tall and has a fibrous root system. It produces a single stem that bears a solitary flower with showy, violet-blue petals that surround a central cluster of yellow stamens. The flowers bloom in early spring, from April to May, and are followed by feathery, silver-haired seed heads that resemble small dandelion clocks.

Appearance
The Alpine Pasque Flower has a distinctive appearance that sets it apart from other plants. Its leaves are basal, meaning they grow from the base of the plant, and are divided into narrow, deeply lobed segments that give them a fern-like appearance. The leaves are covered with silky hairs that give them a silvery sheen. The stem of the plant is also covered with silky hairs, and terminates in a single, showy flower that is 3-5 cm in diameter. The petals are violet-blue and have a satin-like texture, while the central cluster of stamens is yellow and conspicuous. The feathery seed heads that follow the flowers are also covered in silky hairs that give them a fluffy appearance.
Care Guide
The Alpine Pasque Flower is a hardy plant that requires minimal maintenance if grown in suitable conditions. Here are some care tips:
- Water: This plant prefers well-drained soil that is kept moist but not waterlogged. It is drought-tolerant and can withstand short periods of dryness, but prolonged drought can cause the plant to wilt and die.
- Fertilization: The Alpine Pasque Flower does not require fertilization, as it is adapted to grow in nutrient-poor soils. However, a light application of balanced fertilizer in early spring may help to promote growth and flowering.
- Soil: This plant prefers alkaline to neutral soils that are well-drained and gritty. It can tolerate poor soil conditions and is often found growing in rocky or gravelly soils.
- Sunlight: The Alpine Pasque Flower prefers full sun to partial shade. It can tolerate shade, but may produce fewer flowers.
- Hardiness Zones: This plant is hardy to USDA zones 4-9, which means it can tolerate cold temperatures down to -30°F (-34°C).
Common Pests & Diseases
The Alpine Pasque Flower is relatively pest and disease-free, but it may be affected by the following:
- Slugs and snails: These pests can damage the leaves and flowers of the plant. Hand-picking or using slug pellets can help to control them.
- Botrytis blight: This fungal disease can cause the flowers and leaves of the plant to rot. Avoid overhead watering and improve air circulation around the plant to prevent infection.
- Root rot: This disease is caused by soil-borne fungi that attack the roots of the plant. It can be prevented by ensuring that the soil is well-drained and not waterlogged.
Habitat
The Alpine Pasque Flower is native to the alpine and subalpine regions of central and southern Europe, where it grows on rocky slopes, gravelly meadows, and in open woodlands. It is well-adapted to survive in harsh environments, and its deep root system allows it to access water and nutrients from deep within the soil. This plant is an important component of alpine ecosystems, where it provides food and habitat for a range of insects and small mammals.
