Product Details

Allium 'Gladiator' produces large lavender-blue florets with a sweet pungent scent in tight, globe-shaped heads the size of a softball atop 3–4' stems. This showy early summer flower is great with Bearded or Siberian Iris. Plant 3 bulbs per sq ft.

The genus Allium (the Latin means "garlic") offers colorful, distinctive, and long-lasting forms that are standouts in the early summer garden. Alliums are sun-lovers and prefer well-drained, even sandy, soil. Deer, mice, chipmunks, and related predators generally avoid this group, so you can plant with impunity. Tuck them among clumps of summer-flowering perennials where the Alliums' withering foliage will be hidden by the expanding perennials.

Every state has agricultural regulations that restrict the shipment of certain plants. We're sorry, but we cannot ship this item to the following states: Arizona, Oregon, Washington.


The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it.

Amazing! More beautiful and colorful than others planted from another company.

Just got to say these alliums are truly spectacular! And so many blooms from each bulb. This is their first year after planting. And the blooms have lasted several weeks. Even after the bloom’s color is gone, the “ball” that remains is attractive and interesting for weeks. Very strong!

Allium Gladiator

Had to write and say how great these flowers are!
I'm on the south shore of Lake Erie and have had great success with White Flower Farms Alliums. This is my third year buying and plantiing and I'll never have to buy again. The flowers are 4 feet tall and the purple globes are nine inches across--more like volleyball size! The ones I planted three years ago now have three to four stalks and bulbs--the ones from last year have two to three. I already divided them once. I planted 24 and now have 60 all of which are huge and last three to four weeks. A very strong tall colorful statement in any bed--and- -deer do not bother them. Highly recommended!!

First season, but strong & beautiful

I wanted some early color in my front garden, and planted 2 allium bulbs last Fall. The lavender color is just beautiful and the unusual round shape is eye-catching. In the photo you can see that my peonies and deep purple irises aren't quite ready, but they'll be taking over the stage very soon. In the meantime, the allium look great with my white rhododendron. I'm sure they'll be taller and the heads will be bigger next year. I plan to order more!

These are majestic!

Plant at least 3 for dramatic effect. They remind me of purple fairy wands and are interesting after the bloom fades as well.

Latin Name Pronunciation: al'ee-um  

Bulb size: 22-24 cm/12-14 cm/6-8 cm (depending on variety) 

The genus Allium (the Latin means "garlic") includes many garden plants that grow from bulbs or bulb-like rhizomes. Allium flowers form dense balls of color at the top of strong stems, and they make excellent displays in the garden or in bouquets. Allium flowers range from purple, burgundy, lilac, silvery amethyst, pink, blue, to yellow and white. Some varieties have scented blooms, but their perfume is usually pleasant and not the least oniony. The scent of the bulbs and leaves, however, may remind you of onions.

Light/Watering: Most Alliums grow best in full sun, with at least 6–8 hours of direct sun a day. Those we offer require well-drained soil and are longest lived in locations where the soil is on the dry side during summer dormancy.

Planting: Plant Alliums more shallowly than comparably sized bulbs, just 1–2 times the diameter of the bulb deep.

Fertilizer/Soil and pH: Alliums prefer well-drained, fertile soil. Fertilize in fall and spring with any bulb fertilizer.

Continuing Care: The leaf tips of many varieties, especially the tall ones, begin to brown before bloom time. Remove the spent flowers (except from varieties that are sterile, such as 'Globemaster') if you wish to prevent them from self-sowing.

Pests/Diseases: Alliums have few problems except when planted too shallowly or in wet soil.

Companions: Place Alliums behind heavy-foliage plants such as Peonies and Iris. Good for bedding, and in mixed borders. Flower heads are good for drying.

Dividing/Transplanting: Alliums rarely need transplanting or dividing, but this can be done when the bulbs are dormant.
