Description
Hundreds of starry purple blooms with delicate silvery tips form these incredible allium flower heads. The magnificent, spherical blooms of Allium 'Gladiator' are up to 15cm (6") across! Flowering only once in a season, the blooms are followed by skeletal seedheads for a spectacular autumn display. Undemanding and easy to grow, these purple alliums are guaranteed to add the 'wow' factor to borders and cut flower arrangements. Height: 120cm (48"). Spread: 15cm (6").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Alliums thrive in light sandy, well drained soil in full sun. Avoid planting in cold wet soils as the bulbs are prone to rot in these conditions. Plant allium bulbs at a depth of 10cm (4") and a distance of 10cm (4") apart. A slow release fertilizer can be added to poor soils at the time of planting to improve fertility. When growing alliums, plant them where the leaves of other plants will cover the base of their stems. This will hide the old foliage which dies back before flowering begins.
More Info
Alliums require little maintenance. Leave stems of faded allium flowers intact to enjoy their spectacular seed heads in autumn. Divide overcrowded clumps of alliums after flowering. Caution: irritant to skin and eyes.
