The Marshalls Garden Allium Bulbs 'Caeruleum' (20 Pack) are an ideal choice for gardeners looking to add vibrant, electric blue accents to their borders or container displays. These hardy bulbs provide striking rounded flowerheads on tall stems, offering significant pollinator benefits for bees and other insects; however, they require well-drained soil and patience as the foliage must be left to die back naturally after the blooming period ends.

These bulbs should be planted in the autumn, specifically between September and November.
Plant the bulbs at a depth of 10 to 15cm.
Yes, they are an excellent choice for pots as long as the containers have good drainage holes and are placed in a sunny location.
No, you should allow the foliage to die back naturally. This is essential for the bulb to absorb nutrients for next year's blooms.
Yes, Allium caeruleum is specifically noted for being a pollinator-friendly plant that attracts bees and other insects.
The flowerheads appear on tall stems that reach approximately 60cm in height.
This often indicates insufficient sunlight. Move containers to a sunnier spot or choose a more sheltered location for border-planted bulbs.
Check soil drainage. If the ground is waterlogged, the bulbs may have rotted during the winter; ensure you are using well-draining soil next season.
For optimal growth, plant your bulbs between September and November. Dig a hole to a depth of 10 to 15cm, ensuring the pointed end is facing upward. Space bulbs approximately 10cm apart to allow for proper airflow and root development. They prefer soil that is moist but well-drained; if you have heavy clay soil, mix in horticultural grit or sand before planting. After the flowers fade, resist the urge to trim the leaves. Allow them to yellow and wither completely, as this allows the bulb to store energy for the next growing season.
