Product Details

Product Details

This is the biggest and many think the best Allium yet. Small, silvery purple florets form 8–10″ flower heads. 'Globemaster' gets its 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.

Shipping

Shipping
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: NEVADA, IDAHO, WASHINGTON.

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. Estimated dates for shipping are indicated in the Shipping Details box for each item. Please refer to the Shipping Details box to determine the earliest shipping time. Unless you specify otherwise, fertilizers, tools, and other non-plant items are shipped with your plants or bulbs. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at expected time of delivery.

OUR GUARANTEE

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. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Beautiful show in the garden!

Trying my hardest from Hinsdale, IL

This is the largest, deepest purple bloom that's about 10 inches in diameter. It came into bloom six+ weeks ago and is still standing in its glory. Worth the extra cost for the drama and beauty it brings to the garden.

Stunning tall beauty

weekend gardener from Bellevue, WA

Globemaster seems too expensive to buy, but it is absolutely the best of the allium options - the size of the flower head is huge, it's one of the things that stops people walking in front of my house in May. Give them a bit of room, plant 3 or 6 to try them out. After the bloom is over, even the dried heads look cool, because of the round shape.

This Allium should be in every garden.

Michelle, Master Gardener from Ellison Bay, WI

I planted in my front garden among other perennials and had several cars stop in front of the house just to look closely at these giant Alliums. They are definitely a statement plant.

Wonderbulb!!!

Valentina from NY

This allium is absolutely incredible! First ordered three bulbs and, after seeing them bloom in person, went ahead and ordered 18 more. They stand out b ecause of their beaty and size, yet they blend in seemlessly with other plants (mine are planted with bearded iris Immortality and Captain's Choice). They are in bloom for weeks, looking better and better! The first three planted returned this spring with no winter protection or any special handling.... Just cannot say enough about this plant....

Growing guide

Pronunciation: al'ee-um  

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.
