Description
In today’s gardening world, where garden centres invariably stock very compact plants that display well in the pot, finding tall-flowering plants can be difficult. But not if you choose bulbs – and the giant ornamental onion Allium 'Giganteum' should top your list. Its flower stems reach a height of 1-1.5m, and each sturdy stem is topped with a perfect globe of purple florets. The effect is striking to say the least!
To get the best out of your giant Alliums, plant Allium 'Giganteum' in groups, either near the back of flowering borders, or on their own. Now, it’s just a matter of waiting till late-spring for flowering magic to happen.
