USDA Plant Hardiness Zones

To help gardeners understand which plants will grow well for them, the entire USA has been segmented into ‘Plant Hardiness Zones’. Knowing your zone number is helpful when shopping for plants because:

  • Cold-area gardeners can avoid buying plants that simply won’t survive their lowest winter temperatures.
  • Warm-area gardeners can steer clear of plants that need a period of cold weather in order to bloom again.

Plant Information

This incredible Allium creates a sensation in any garden. The colossal round flower heads are up to a foot across! The color is lovely too, and many gardeners use these unique blooms in various ways. Of course, they're astonishing in an arrangement (Any onion scent dissipates quickly). What's more, this Allium holds the petals on the flowers after blooming, so it makes a spectacular addition to dried arrangements. Some crafters even paint them--with various colors or with gold paint for the holidays.

About the Alliums. Every family has its beauties. And yes, these are the best-looking members of the family of Allium, which includes onions, leeks and chives. (The word, Allium, means 'onion' in Latin.) Many Allium species are native to Iran, where many tulips also originate, and the edible Alliums have been cultivated and a staple of diets for over 10,000 years.

The beauty of the small lavender flowerheads of chives have always been a decorative highlight in herb gardens. But in recent years, gardeners have become fascinated with the larger Alliums, particular the giants. As always, the Dutch hybridizers took them into their stocks, and now we have a whole group of beautiful new flowering onions for gardens. Most bloom in late spring so they bridge the gap nicely between the tulip season and early summer bloom of peonies and poppies.

Experienced gardeners plant these giant Alliums in groups of several bulbs, set very close together. The foliage is not attractive for long, so it's important to plant them next to other perennials whose foliage will more or less cover the Allium's base. This way, the wonderful flower stalks rise up and tower over the other flowers for a wonderful period of bloom.

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'm hoping they'll multiply, but I plan to order more!

I was disappointed with the bulb, it looked like a part of it was sliced off. I planted it anyway. It grew, but the plant was so tiny, flimsy, and did not have a dense flower head. So no where as beautiful as the aliums in these pictures. Maybe next year it will look healthier, who knows. I hope so.

      The Globemaster alliums I received from you are starting to grow now that the weather is getting warmer! The wide green foliage coming out of each bulb is several inches above the ground. I can't wait to see the blooms...they're gonna be huge!!

            This was my first year growing these wonderful flowers. I just happened to stumble across them in my search for fall planted bulbs. They are magnificent. I did make the mistake however of A. only buying a couple and B. planting them by themselves. I think they would look even more attractive with flowers or ferns possibly that come mid high on them. Just because their greenery doesn't look quite so pleasing on its own. So I bought 6 more this coming fall.

                      I have quite a few of the regular Alliums in my flowerbed. I've always had people drive by and ask what they were and a few neighbors have added them to their flowers as well. I decided to buy 2 of the BIG GlobeMaster bulbs to try. The first year, it was hard to tell the difference between them and the regular Alliums, but this year, they are BIG! Super big base with a very large flower at the top. The stem is nice and sturdy to hold this big fella up!!!!! LOVE IT! Perfect in Wisconsin and they come up every year no problem.

                                  Absolutely beautiful! I bought twenty for a mass planting. The bulbs I received were very large and in excellent condition. The blooms in spring were huge with almost every flower head 7 to 8in. I can't recommend them enough.

                                        Allium Globe Master is a must have for the garden. Stunning display of huge purple globes swaying in the breeze. Neighbors have stopped by to admire these incredibly beautiful purples globes. I planted these in the back of my flower beds.

                                            I put the Allium Globe Master in with beds of Indigo Salvia. It's simply breathtaking! I'm incredibly pleased with the product. Every bulb produced a bloom, and most of the blooms are really big. I highly recommend this beauty!

                                              I saw these in the Boston Public Gardens and just had to have them in my own back yard. I'm very excited about them and so aren't a few of my neighbors.

                                              Q & A

                                              Plant With These:

                                              USDA Hardiness Planting Zones

                                              To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

                                              • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
                                              • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

                                              Find Your Planting Zone:

                                              Enter your Zip Code to find your USDA Planting Zone
