Description
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.
