About Crocus heuffelianus 'Shock Wave'
'Shock Wave' was selected from seedlings of Crocus heuffelianus for its particularly distinctive flowers. Each bloom combines a soft lilac background with sharply contrasting violet markings concentrated towards the tips of the petals.
Fine feathering extends from these darker areas into the paler portions of the petals, creating an intricate pattern. When the flowers are still closed, the repeated violet markings form an especially attractive display, while warmer, brighter conditions encourage the flowers to open and reveal their paler interiors.
Distinctive Lilac and Violet Flowers
The two-tone flowers make 'Shock Wave' particularly useful for gardeners looking for something different from traditional plain-coloured crocuses. Its pale lilac petals provide a soft background for the much darker violet tips, allowing the markings to remain clearly visible even from a distance.
Planting the corms in groups enhances the effect. A cluster of flowers creates a mass of lilac and violet markings amongst the narrow green foliage and looks particularly attractive alongside white, yellow or deeper purple spring bulbs.
Growing Crocus 'Shock Wave' in the UK
Plant Crocus 'Shock Wave' corms during autumn in fertile, well-drained soil. A position in full sun is ideal, although light shade is also suitable. Like most crocuses, the flowers respond to sunshine by opening more fully during bright weather.
Good drainage is important, particularly during the dormant period. Avoid planting in areas that remain persistently waterlogged. In heavier soils, adding grit or other free-draining material around the planting area can help create more suitable conditions.
A Hardy Crocus for Rockeries and Borders
'Shock Wave' is fully suited to outdoor cultivation and works especially well in rockeries, gravel gardens, raised beds and towards the front of mixed borders. Its small flowers are best positioned somewhere they will not become hidden behind larger plants.
Planting close to a path or patio also gives you the opportunity to appreciate the detailed feathering and unusual violet petal tips at close range.
Growing Crocus 'Shock Wave' in Containers
This compact crocus is an excellent choice for pots and troughs. Plant several corms together in free-draining compost for a concentrated spring display. Containers can be positioned in a sunny location near entrances, patios or seating areas where the flowers can easily be enjoyed.
'Shock Wave' can be grown alone or combined with miniature narcissi and other early spring bulbs. Its lilac and violet colouring works particularly well alongside white and pale yellow flowers.
Naturalising Crocus 'Shock Wave'
Crocus 'Shock Wave' is also suitable for naturalistic planting beneath deciduous trees and shrubs or through suitable areas of short grass. Plant corms in informal groups rather than straight rows for a more natural appearance.
Once flowering has finished, allow the narrow foliage to remain until it has yellowed and died back naturally. The leaves continue feeding the corms and help them store enough energy to produce another display the following year.
