You simply won’t believe the size of these giant allium bulbs when they arrive – they’re absolutely humungous! There’s no doubt about the fact that big bulbs like this will put on a big show, and when it comes to flowering, with a huge 35+ size bulb anchoring it into the ground you can be certain that your ultra-impressive allium display will be strong, upright and long-lasting too!
Allium ‘Ambassador’ is one of the most stately of all the giant alliums, growing to a height of over 1m tall and with substantial, dense flower clusters up to 20cm in diameter. The vivid purple ball-like flower clusters nod proudly in beds and borders during May and June to help the spring colours effortlessly flow into summer – if you want to impress your guests and neighbours, this jaw-droppingly burly one is bound to do the trick! If you enjoy creating spectacular indoor flower arrangements, this versatile flower is exceptionally long lasting in a vase and is great for both contemporary and relaxed styles.

Plant profile
Plant calendar
Choose full sun or partial shade. Improve heavy soil with organic matter and horticultural grit. For containers, use peat-free multipurpose compost with good drainage.
Plant bulbs pointed side upwards, two to three times their own height deep. A slightly flattened side is perfectly normal and nothing to worry about.
Space small bulbs around 5cm apart. Larger bulbs need more room, generally around twice their own width apart, so their foliage and flowers can develop freely.
Water after planting if the soil is dry, then only when needed. After flowering, allow the foliage to die back naturally. Decorative seedheads can remain in place.
