Product Details
'Globemaster' is the biggest and many think the best Allium yet. Small, silvery purple florets form 8–10″ flower heads. This bulb gets its large flower size from its A. cristophii parent, but the florets are packed more densely, creating an imposing and brilliantly colored globe. Late spring. Plant 3 per sq ft.

HOW PLANTS ARE SHIPPED
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.
WHEN WE SHIP
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.

Fabulous! 
A viewer from Cape May, NJ
Planted in the fall. They came up in April and still going strong in May. The longest lasting bulb flower in history! Gorgeous, stayed upright after lashing wind and rain. Ordering more for next year right now!

Thrilled
A viewer from Long Island, NY
Couldn't be happier. Planted 6 of these last November and got 6 perfect plants with big globes that have lasted for weeks. I was initially concerned since few spots in my yard get full sun but the partial sun (non-continuous 4-5 hours) of this spot must have been perfect for Allium.

Sad 
A viewer from The Colony, Texas
Super disappointed. Planted in well drained soil with appropriate sun exposure and only two bloomed. The blooms were shorter than advertised and sort of pitiful.

I am sorry these bulbs did not perform as expected Karen. As they are guaranteed I will be contacting you via email regarding compensation.
Sincerely,
Cathy

Beautiful Standout!
A viewer from Northern Ohio
I purchased a home with a perennial garden that included 2 Allium. I decided to add more so I bought 12 Globemasters. I am not disappointed. They receive total sun and are majestic, stand tall and have the largest ball of purple flower that Ive ever seen. I am a novice at gardening so if they will grow for me, they will grow for anyone. I am buying more for the other side of my garden. Definitely recommend!

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.
