Product Details

Allium 'Purple Sensation' bulbs produce plants with reddish violet balls 4–5" across, borne on 20–30" stems in late spring. This is the earliest of the large-flowered Alliums and also among the most affordable. Outstanding with silver foliage, and with Bearded Iris or Lady's Mantle (Alchemilla). Late-spring. 3 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.

Gives detail to the back of a garden due to the height of these allium.

Showy Blossom!

I planted these under a bed of hosta last fall and forgot that I did so. What a fun surprise when they started peeking out from under the hosta and kept growing taller until they finally burst out with this lovely feathery purple ball. The blossom is large but not as large as the giant alliums I've seen. I love these and plan to order more. This time I'll remember I planted them!

Allium 'Purple Sesation'

We kept the lovely purple colour longer, for a garden party, by spray painting the seed heads a perfectly matching purple. Even our visiting, internationally famous garden experts didn't notice the scam.

WOW! Early, and lovely.

It's really something, and I'll be adding more all over this year.

Great addition to my pond plantings

So far, my favorite new addition to the garden, this year. I took the suggestion to plant with ladies mantle and bearded iris, since I already have these planted around my small, slate-edged fish pond. What a great idea. The ladies mantle provides a hiding place for the small, unimportant leaves below. The stems rise above and between, adding such a punch of color and textural interest. Almost identical in color to the purple bearded iris I have growing at one end, but with the addition of a reblooming white and yellow, I expect next year will be even better. I am sorry to see them go. They bloomed a little before the iris, which are still around. Wish they lasted a little longer.

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.
