Marshalls Ultimate Allium Collection is a superb selection of four of the most spectacular alliums to add colour and excitement to your garden in early summer. Bees and other pollinators love the flowers, and the dried seedheads keep on looking great months after the flowers have faded. They also make gorgeous cut flowers.

The collection contains:

• 20 x Allium 'Purple Sensation' bulbs - Rich purple round flowerheads on 1m (3.5ft) stems
• Allium 'Caeruleum' bulbs - Bright blue round flowerheads on 60cm (2ft) tall stems
• Allium 'Sphaerocephalon' bulbs - Oval flowerheads change from pale green to rich wine-red. Long stems create beautiful contrast with ornamental grasses and attract bees and pollinators.
• Allium 'Cristophii' bulbs - Allium cristophii's spherical starburst of purple flowers stands tall in sunny gardens, adding interest even after blooms fade.

How you will receive your bulbs:

Selected by our team of experts and sent from our nursery, you will receive spring-flowering bulbs in the autumn in a breathable mesh bag. This is to keep the bulbs together in a pack that is nice and airy – perfect to keep the bulbs healthy while in transit.

Can’t plant straight away?

Keep your bulbs in a cool, light, and dry place and preferably hanging on a hook so that air can get to the bulbs at all angles. Ideally, you should aim to plant your bulbs within a week of receiving them, but if this is not possible, store them in a cool, dark place until you are ready to plant them.

Planting tips and hints:

Planting in the ground: You can plant your allium bulbs any time between September and November. Dig a hole with a trowel or a bulb planter 3 times the depth of the bulb, approximately 10-15cm deep. If your soil is heavy, mix in quality bulb compost and potting grit to give them the best start. Place the bulb in the hole with the tip facing upwards, then fill the hole and compact the soil gently. Water in to moisten the soil and apply a bone meal fertiliser to encourage flowering.

Planting in containers: Place a layer of stones or gravel at the bottom of a large container in order to aid drainage. Fill the container with bulb compost to approximately 20cm below the rim. Place bulbs approximately 5-8cm apart ensuring the tips face up. Fill the container to about 3cm from the top of the rim making sure to firm the compost between the bulbs. Water just enough to settle the soil, then place the container in a sheltered place over autumn and winter before moving into a sunny place when the shoots are around 5cm tall.

Feeding and aftercare: When feeding in spring, use a liquid feed high in potash.
