A Florist's Guide to Crocus
Crocus, a delightful genus of flowering plants within the iris family (Iridaceae), is renowned for its vibrant colours and early spring blooms. Perfectly suited for gardens and pots alike, Crocuses are a must-have for both seasoned florists and budding enthusiasts.
Species Overview
Crocus flowers are available in various species, the most popular being:
Crocus vernus: Often referred to as the spring crocus, featuring large, cup-shaped flowers in shades of purple, yellow, and white.
Crocus chrysanthus: Known as the golden crocus, this species produces smaller, delicate flowers primarily in yellow and white.
Crocus tommasinianus: Commonly known as Tommasini’s crocus, it offers early blooms in a lovely violet hue.
Growing Conditions
Soil
Crocuses thrive in well-drained, sandy or loamy soil. They prefer a slightly acidic to neutral pH (6.0 - 7.0).
Sunlight
These plants enjoy full sunlight but can tolerate partial shade. Aim for a location that receives at least six hours of sunlight a day.
Watering
Crocuses need moderate watering, particularly when first establishing. Once the bulbs are planted, ensure the soil remains moist but not waterlogged. Overwatering can lead to bulb rot.
Planting
Timing
The best time to plant Crocus bulbs is during autumn (September to November), allowing them to root before winter.
Depth and Spacing
Plant bulbs approximately 10-15 cm deep, spacing them about 5-10 cm apart. This spacing allows room for growth and promotes airflow, reducing the risk of disease.
Care and Maintenance
Crocuses are relatively low-maintenance. After flowering, allow the foliage to die back naturally, as this process helps the bulbs store energy for the next season.
Fertilising
A balanced fertiliser can be applied in early spring while the leaves are active. Avoid fertilising after flowering to prevent stimulating excessive leaf growth at the expense of blooming.
Pest and Disease Management
Crocuses are generally resistant to pests and diseases, but vigilant care is essential. Keep an eye out for common issues such as bulb rot and aphids. Proper drainage and airflow will mitigate many problems.
Seasonal Arrangements
Crocuses are ideal for fresh spring arrangements. Their bright colours can be paired with complementary flowers like daffodils, hyacinths, or even delicate grasses for texture. Consider using them in pots for a charming display on patios or balconies.
