Alliums are extremely popular in flower beds across the world, while the most common ones are purple, but there are a couple of white flowering alliums as well. If you love the shape of the allium flowers and you want a more neutral color in your garden then you should definitely grow some Allium Mount Everest. The Allium Mount Everest is also called the Ornamental Onion Mount Everest, and Allium Stipitatum Mount Everest.
Generally speaking, the Allium Mount Everest looks better in gardens if it is grown in clumps of 6 or more, due to the relatively large stem on which the flower is it will be the focal point of the garden. It is also a good idea to plant it either in the midsection or at the back of the garden, especially as its leaves are not the best-looking ones. You should also grow Oxalis Iron Cross with alliums as they will cover their leaves which are not the best looking ones, for more information check out my recent article Oxalis Iron Cross ( Good Luck Plant ).

Although for the most part Alliums do not need to be staked, but they could use some support, or else in the first storm they might flop, my personal recommendation is to use 36-inch stakes specially made to support single-stemmed plants Click here to check it out on Amazon.com
Allium Mount Everest Characteristics
The Allium Mount Everest is part of the Allium family, and it is usually grown from bulbs. It is considered a perennial bulb which means that it will come back every year, although in colder climates than Zone 4 you have to treat it as an annual plant. The Allium Mount Everest creates extremely beautiful flowers, and for the most part pests and even deer leave it alone.

Allium Mount Everest Hardiness Zone
The Allium Mount Everest is hardy from Zone 4 to Zone 8, it is extremely cold tolerant but not as heat tolerant. In hotter climates, you might want to plant it in partial shade, or the allium might get extremely floppy. Even though it is a hardy plant, it doesn’t like having too much moisture around the bulb especially if the temperatures are below freezing. Make sure to pick a well-draining spot for this plant if you have relatively humid winters.
Allium Mount Everest Sun Requirements
Between Zone 4-8 you should plant the Allium Mount Everest in full sun, if you are in hotter climates then partial shade would be better. The one thing that Allium Mount Everest hates the most is full shade, oftentimes the allium will simply not bloom or even die out if it is placed in full shade.
Allium Mount Everest Water Requirments
The Allium Mount Everest doesn’t have any special water needs, as long as the soil around it is relatively moist it shouldn’t have a problem. During hot days you might notice that the allium might start to flop, this is a clear sign that it needs more water.
Allium Mount Everest Drought Tolerance
The Allium Mount Everest tolerates drought extremely well like all plants in the allium family. If the drought is severe or long enough you might notice it flop, but this mostly happens in hot and dry environments.
Allium Mount Everest Height And Width
The Allium Mount Everest tends to grow somewhat tall, usually, its height is between 2-3 feet ( 60cm-90cm ). In some cases, it can get even higher, but usually, this tends to happen when it has too much competition in the garden from other taller plants. Its width is between 1-3 feet ( 30cm-60cm ), although its leaves tend to die out relatively fast.
Allium Mount Everest Flowering Period
The flowering period of Allium Mount Everest is between spring and summer, in colder climates, it tends to bloom at the start of the summer rather than in spring. In hotter areas, it can bloom for several months, as long as it gets plenty of sun and plenty of water.
Allium Mount Everest Planting
Planting the Allium Mount Everest is relatively easy, just measure the size of the bulb and plant it 3 times deeper than its height. Make sure to place the pointy side of the bulb facing towards up, this way the bulb doesn’t have to use its energy to realign itself so it grows correctly. Make sure to use some kind of compost or even a slow-release fertilizer when planting as the allium bulbs tend to be hungry. The best time to plant is during the fall, just make sure you plant it around 6-8 weeks before your first frost date.
Allium Mount Everest Staking
For the most part, the Allium Mount Everest doesn’t need to be staked, although if your allium is starting to get leggy or you live in an area with constant winds then you might have to stake it.
Allium Mount Everest Propagation
You can propagate the Allium Mount Everest by dividing the bulbs or by letting it self seed. In the second year of planting the allium, should start making small bulbs, you can either leave these in the ground and let it naturalize or dig them up and divide the bulb. After the allium has finished blooming it will create a lot of seed heads, these can be collected easily and you can spread it around the garden.
Allium Mount Everest Self Seeding
All plants from the allium family tend to self-seed and this is the same case with the Allium Mount Everest. The good news is that this plant is not as an aggressive self-seeder as some other alliums. You should deadhead the allium before it produces seeds, and the ones that germinate are extremely easy to dig out.
Allium Mount Everest Deer Resistance
The best part about the Allium Mount Everest is that deer will leave it alone, I don’t know how it tastes but deer do not seem to bother with it. This is the case both for its flowers and for its leaves as well.
Allium Mount Everest Rabbit Resistance
Rabbits tend to avoid most plants in the allium family and this is the case of the Allium Mount Everest as well. Although rabbits might occasionally nibble on the young shoots if they are hungry enough.
Allium Mount Everest Pet Friendliness
All plants in the allium family do have some toxic properties to cats and dogs. Although your pets will need to eat a lot of allium bulbs in order to get sick, so unless your cat or dog has suddenly turned vegan I wouldn’t worry about it too much.
Allium Mount Everest Pests
The Allium Mount Everest doesn’t really have any pests once it is mature. On the other hand during the spring when it starts growing you might want to keep the slugs and snails away from it. This is a crucial period for them and if they get damaged at this stage they might not have enough energy to bloom or to push through the soil.
Allium Mount Everest Diseases
The Allium Mount Everest is prone to a couple of diseases like onion rot and downy mildew. Generally speaking, both of these diseases tend to happen when either the bulb sits in water thus rotting it, or in the case of the downy mildew, the plant is constantly wet.
Allium Mount Everest Indoor Care
Ideally, you should plant the Allium Mount Everest outside in your garden as it really struggles indoors. In case you want to grow it indoors you should choose a spot where it can get plenty of direct sunlight, and make sure to fertilize it from time to time.
Allium Mount Everest Soil Type And Ph
The Allium Mount Everest can be grown in every kind of soil like clay, loam, or sand as long as it is well-draining. It doesn’t have a specific PH requirement so it will have no problem growing in alkaline, neutral, and even in acid soils.
Is The Allium Mount Everest Invasive?
No, the Allium Mount Everest is not invasive, it might produce a lot of seed heads but not all of them will germinate. You might notice the odd allium in different parts of your garden where you didn’t plant it but you can simply dig it up.
Can Allium Mount Everest Be Grown In Pots And Containers?
Yes, the Allium Mount Everest can be grown in pots and containers, although it does perform better if it’s outside rather than inside your home. Make sure to use a high-quality and well-draining soil if you want to plant it in pots, and keep a close eye on it not to dry out.
Can I Grow Allium Mount Everest In My State?
The Allium Mount Everest can be grown in every state, although in areas below Zone 4 and Above Zone 8 you should grow it as an annual, which means digging up the bulbs for over-wintering them. If you are not sure in what Zone you live in then take a look at the USDA Plant Hardiness Zone Map.
