Common Questions

• Do Allium leaves die back before flowering
Yes, the foliage often begins to die back before the flowers fully open, which is completely normal for ornamental alliums.

• Does Allium ‘Ambassador’ need staking
No, the thick stems are strong and usually support the large flower heads without assistance.

• Will it come back every year
Yes, it is a fully hardy perennial and will return each year once established.

Planting Ideas

Allium ‘Ambassador’ works best planted among low growing perennials or ornamental grasses, which help disguise the fading foliage while allowing the flower stems to rise clearly above.

More Information

Plant in full sun in well drained soil, avoiding areas that remain wet in winter. Water well after planting.
You can plant at any time of year provided the ground is not frozen or waterlogged. If planting during warmer weather, water regularly until established.
The foliage often dies back before the plant flowers. Planting low growing perennials or ornamental grasses around the base helps cover the leaves while the flower stems emerge.
Leave seed heads for structure or remove once flowering finishes.
