Allium Luna Luna Ornamental Onion

Allium 'Luna' is a striking ornamental onion known for its globe-shaped, bright white flower clusters that bloom atop slender, upright stems. These flowers create a beautiful, moon-like appearance, which is where the name 'Luna' originates. The plant has narrow, strappy green leaves that typically begin to fade as the flowers emerge, allowing the floral display to take center stage.

In Melbourne's climate, Allium 'Luna' thrives in full sun with well-draining soil, particularly during its active growing season in spring and early summer. Plant the bulbs in autumn, spacing them around 10-15 cm apart and burying them at a depth about two to three times the height of the bulb. Ensure that they receive consistent watering during establishment but reduce moisture as they approach dormancy after flowering. These plants are relatively low-maintenance and tolerate drought well once established. 

To enhance flowering, it's best to fertilize in early spring with a balanced, slow-release fertilizer. Deadheading spent blooms and allowing the foliage to naturally die back helps replenish the bulbs for the next growing season. With proper care, Allium 'Luna' will reward gardeners in Melbourne with a striking summer display year after year.

Allium 'Luna' pairs beautifully with a variety of companion plants that complement its striking spherical blooms and benefit from similar growing conditions. Plants with contrasting textures or colors can enhance the visual appeal of Allium 'Luna's white globes. Ornamental grasses, such as blue fescue or Mexican feather grass, provide a soft, wispy backdrop that contrasts with the structured shape of the allium flowers. Perennials like lavender, nepeta (catmint), and salvia, with their purple or blue hues, create a lovely color contrast against the white blooms.
