Corydalis
Corydalis (particularly C. solida) supports early spring pollinators with its nectar-rich, tubular flowers, which are perfectly adapted for long-tongued bumblebees like Bombus hortorum (garden bumblebee). Its extended blooming period (February – June) bridges vital gaps in forage availability. The delicate foliage hosts larvae of the Plutella moth species, while its seeds attract ground-foraging birds like robins (Erithacus rubecula). Ideal for shaded rockeries or woodland edges, Corydalis thrives in well-drained soil, naturalising effortlessly alongside native primroses. Its ecological resilience and prolonged flowering make it a keystone plant for urban woodland gardens.
Frequently Asked Questions
When is the best time for autumn planting of spring bulbs?
The ideal time to plant spring flowering bulbs like tulips, daffodils, crocus, and snowdrops is from September to November. Planting during this period allows bulbs to establish roots before winter and ensures a healthy, vibrant bloom in early spring, with stunning green foliage and flower colours ranging from purple and blue to bright yellows and whites.
How long do spring bulbs take to flower?
Most spring bulbs planted in autumn start to flower between February and May, depending on the type. Early bloomers like snowdrops and crocus appear first, while tulips and daffodils follow later in spring, creating a sequential display of colour.
Can I plant different types of spring bulbs together?
Yes! Mixing different bulbs such as tulips, daffodils, and muscari adds something extra in terms of colour and texture to your garden. Planting in clusters or drifts creates a natural, layered effect, letting you get a longer flowering season and a richer display for both you and pollinators.
Do I need to remove foliage after flowering?
Yes, but allow leaves to die back naturally rather than cutting them too early. Leaving the foliage lets the plant save energy, which the bulbs use to produce strong, vibrant flowers come next spring.
