Alliums: The Globe-Shaped Garden Stars That Will Transform Your Landscape

Alliums in the Garden

Alliums are globe-shaped flowering bulbs from the onion family. Their round blooms add a strong vertical accent to borders and look good in the ground or cut for vases.

What Alliums Are

Alliums, also called ornamental onions, form a sphere of small flowers on a straight stem. The shape stands out among lower planting.

Where to Place Them

Alliums do best at the back of a border, where their height frames lower plants.

Why Grow Alliums

Alliums add height and round forms that most perennials lack. They feed bees and give a border a structured look after spring bulbs fade.

Alliums are a low-effort way to add a strong shape to the garden.
