Product Information

A stunning sight, ‘Red Giant’ is quite unlike any other allium. With its relatives renowned for their tall, stiff stems that carry flowers high above the low growing foliage, this incredible variety does the exact opposite!

In May and June, the flowerhead emerges and erupts into a globe, 12 cm (5 in) in diameter, made up of dozens or small, reddish purple flowers sitting just above the broad, arching green foliage. Recommended by the RHS as a ‘Plant for Pollinators’, Bees and butterflies adore ‘Red Giant’ just as much as any other allium.

An ideal and unusual plant for growing at the front of borders, it also works extremely well when planted in groups in containers, having a very architectural look when in flower. Even though the stems are short, the flowers still look great indoors and in bouquets, whether fresh or dried, and they add winter interest, and an insect habitat, if left on the plant over the winter.

Alliums aren’t fussy about soil type but do prefer a sunny location. They will naturalise easily, multiplying over the years. Clumps can be dug up and split every few years, which will stop them becoming congested.

Supplied as 5 bulbs, size 12/14, ready to plant in autumn, growing to a height and spread of 25 cm (10 in).

Top Tips

Underplant with hostas, ferns or other low-growing, hardy perennial plants which will help to disguise the leaves as they fade.

Care Information

Planting Advice for Alliums

  • Find a location where the soil drains well and where they will receive full sun.
  • Plant allium bulbs in early to mid-autumn in a sheltered site to prevent the top-heavy flower spikes from getting blown over.
  • Dig over the soil and remove any weeds before planting.
  • Water well after planting, saturating the soil around the bulbs. Once established, alliums are drought tolerant.
  • In borders, plant bulbs in early autumn at a depth of about four times the diameter of the bulbs.
  • In containers, alliums will do well in deep pots with a good general-purpose potting compost with a handful of horticultural grit added. 

Aftercare Advice

  • After planting, feed with a general-purpose feed such as our Blooming Fast Superior Soluble Fertiliser.
  • Dried flower heads can be removed and made into indoor decorations or left on the plants to self-seed.
  • Divide alliums every three to four years or when the plants begin to look overcrowded and blooming decreases.
  • Lift the bulbs with a garden fork or spade and pull the bulbs apart.
  • Replant some in the original location and plant the remainder in a new location. 

Pruning and trimming advice

  • The leaves die down at flowering time, so it’s best to plant alliums where this foliage is masked by that of other plants.
  • Avoid removing them while still green, as they provide the bulbs with energy for the following season.
