Product Details

We've selected a trio of large-flowering, long-blooming Allium varieties that deliver an extended show of traffic-stopping blooms from spring into summer. All produce flower heads that measure up to 5” or more. They rise on tall stems like beautiful purple balloons floating in the sunny border. Super for foundation plantings, too. We ship 3 bulbs each of Allium giganteum, 'Globemaster,' and 'Gladiator.' 9 bulbs total, labeled. Planted together, this collection covers approximately 5 sq ft. Or plant them around the garden where their colorful forms make eye-catching accents.

Although bloom times can vary, the bulbs will bloom generally in the following sequence: 'Globemaster,' 'Gladiator,' and Allium giganteum. We recommend tucking the bulbs among clumps of perennials, where the leaves of the Alliums will be conveniently hidden from view as they fade during the summer.

The genus Allium (the Latin name 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 Allium's withering foliage will be hidden by the expanding perennials.

Shipping Info
Every state has agricultural regulations that restrict the shipment of certain plants, and select non-plant items may be subject to other shipping constraints. As a result, we cannot ship this item to the following states: ID, OR or WA.

We want our customers to receive strong, healthy plants that are ready to thrive in their gardens and homes. Here's what we'd like you to know about our shipping practices.

Delivery Timing

We aim to deliver your plants at as close to the proper time for planting in your area as possible. To do so, we consider the USDA Hardiness Zone to which we're shipping, current and forecasted weather at the destination and along the shipping route, and whether your plants are ready for transplant.

In spring, we ship first to the warmest regions and move north as planting conditions improve. For fall deliveries, we begin with the coolest regions and work south. We frequently adjust shipping schedules when extreme weather could put plants at risk while in transit or soon after arrival.

Because different plants reach readiness at different rates and are weather-sensitive in varying degree, a single order may be delivered via multiple shipments. Plants sold as part of a collection, or that are otherwise meant to arrive together, will be shipped together. Please contact our customer service team with two weeks' advance notice if you anticipate being away at the expected time of delivery.

Tracking information for each package is delivered via email.

Plant & Container Sizes

We deliver plants in various sizes and stages of growth, and the product detail pages of our website indicate the form and/or pot size in which the plant will be delivered. Pot sizes range from 1 pint to 1 gallon and larger. Many perennials, roses, shrubs and vines are delivered bareroot - that is, not in a container at all. Bulbs and tubers are generally delivered bareroot and fully dormant. We choose container sizes and delivery methods based on how each plant grows best, how we can minimize transplant shock, and how to minimize unnecessary bulk/weight in shipment.

Caring for Your Plants Upon Arrival

It is important to acclimate greenhouse-grown plants to life outdoors. All plant shipments include simple instructions for handling your plants upon arrival. Further how-to information, including planting instructions, is available on each plant's product page.

Growing Guide

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.

Loved these Alliums!

"I purchased this trio group in the Fall of 2018. I am a novice gardener so its always "survival of the fittest" in my garden. They are beautiful!! Majestic and stand tall. We have had a chilly Spring so they didn't bloom until late May but its June 6th and the Globemaster is just blooming and the Gladiator is in full bloom and gorgeous!!"
