There are numerous lovely flower bulbs with unique charms and qualities, including tulips, narcissus, hyacinths, and snowdrops. We want to introduce you to a selection of them in this blog series so you may choose the best ones for your garden and create the spring show of your dreams!
While its relatives the onion and garlic enhance the flavour of our food all year long, decorative onions (Alliums) provide us with all of their benefits in a considerably shorter amount of time. But just as garlic and onions are a feast for our taste sensations, seeing them in bloom is a feast for the eyes. This easy-to-grow plant, which has won the Royal Horticultural Society’s Award of Garden Merit five times, is well-known throughout the world and will undoubtedly become the centre of attention in your late-spring garden. It can grow as high as 5 feet.

- Color
Purple is the traditional colour of Allium, closely followed by white. But you can see that those aren’t the only hues on our Allium page: What about the hues of Allium Moly’s yellow, Allium Scarlet Mohican’s red, or Allium Ostrowskianum’s strong pink?
Bloom period
Alliums peak from mid/late spring to early summer, offering a suitably bombastic end to the flower bulb season.
Longevity
Allium bulbs are perennial and self-propagating, returning each year and spreading a few more seeds with them each spring.
many kinds
Nearly as many different types of allium exist as there are varieties. Their distinctions can be seen in the size of the plants and the appearance of the blooms, which can be traditional like Azureum or odd like Allium Hair or Allium Bulgaricum.
Planting
Alliums prefer a location with some sunshine and soil that drains well. The bulbs should be planted in the fall, with their pointed ends facing up, 4 inches deep for the lesser variety and 6 inches deep for the larger ones. After planting, give your plants plenty of water. By late May or early June, huge, gorgeous globes on towering stalks will beautify your yard.
Forcing
Alliums can be pushed, although they require more freezing time and post-chilling growth time than other bulbs. Place the bulbs with their pointy ends up in a well-draining pot and cover them with one inch of dirt. It’s best to use three bulbs per 6-inch container. Water thoroughly and let drain. Put the pots somewhere cold and dark for at least 10 to 12 weeks. The bulbs may grow healthy, robust roots at temperatures between 38 and 42 degrees Fahrenheit. Do periodically check the soil to make sure it’s still moist enough, and add water as necessary. The pots will need to be transferred to a colder location, between 32 and 25 degrees Fahrenheit, after the first 10 weeks. They must remain here for an another 8 to 10 weeks while being watched for proper moisture levels. After this second freezing period, bring the bulbs to a bright room with a temperature of no more than 55 to 60 degrees Fahrenheit since at higher temperatures, the stalks won’t grow strong enough to hold the bloom. The bulbs in this room will require additional fluorescent lighting, exposing them to light for up to 16 hours a day. Once flower buds begin to form, bring the pots back to a slightly colder environment (50–55F), since this will increase the flower’s lifespan to at least 10 days.
Planting in containers
Locate a sizable, deep pot that has drainage holes, and then fill it with dirt. The sharp ends of the allium bulbs should be planted as deeply as possible. Cover them with dirt, give them plenty of water, and keep them somewhere relatively cool and dark until at least April, when you should relocate them to a location that receives as much sunlight as you can. Potted alliums are great for putting on a striking display on your balcony, rooftop, or porch.
Pricing
Right now, all of our alliums are on sale, making it the ideal moment to choose the kind that best suits your preferences and financial situation. The astonishing Allium Drumsticks have a low price point of $0.18 per bulb for 100, dropping by more than 40% to $0.10 per bulb for 5000. The enormous Summer Drummer has a mid-range pricing range that starts at $1.65 per bulb for 10 and down to $0.94 per bulb for 1000. At 200 bulbs, our Elite Allium Globemaster is discounted by 47%, making each bulb only $4.25 instead of the regular $7.95 price.
Combinations
Given that Alliums are quite the drama queens due to their size, you can either choose to heighten the drama with contrasting flowers, such as yellow Tulip Sunshine Club, or you can choose to lessen the drama by surrounding them with flower bulbs in complementary colours, such as purple Tulip Night Club or Tulip White Triumphator.
Can forced bulbs be planted?
After blossoming, tulips, hyacinths, and the majority of other spring-flowering bulbs that have been forced indoors are typically thrown away. Most plants that are put outside won’t blossom again. There is an exception: daffodils. Compared to tulips and the majority of other spring-flowering bulbs, daffodils are more robust. Daffodils that have been forced can be successfully rescued and planted outside.
Taking good care of pushed bulbs after flowering is crucial if you want to keep them. After blooming, take off the wasted flowers and put the plants in a window that gets enough of sunlight. Water the foliage frequently until it starts to turn yellow. At this stage, reduce watering gradually until the foliage shrivels and dies. The bulbs should be carefully removed from the potting soil, let to dry for one to two weeks, and then stored in a cool, dry area. In the fall, plant the bulbs.
Are allium bulbs freezer safe?
Hello, To plant this fall, I purchased about twenty huge white allium bulbs. I’m afraid I won’t be able to because the planting area still needs to be adjusted since it is largely clay. I want to keep them in storage until the upcoming fall of 2019 and the winter. I am aware that they require a warm, dry area that doesn’t freeze. Given that it stays somewhat chilly and the bulbs won’t freeze, I believe the heated garage will work. I previously took the bulbs out of their packing in the mistaken belief that I was going to get them planted, so they are currently sitting loose in a box. Is it required to store them in peat moss or vermiculite? Or can I separate them using newspaper? In addition, can I leave them in the garage when the weather becomes warmer or should I transfer them to a cooler location in the basement? How can I make sure that the bulbs won’t begin to produce foliage when the temperature warms up in the upcoming spring or summer? Any assistance you can provide would be greatly appreciated. Thanks
To prevent excessive moisture buildup and bulb rot, it’s crucial to keep bulbs in breathable materials over the winter. It’s simple to store your allium bulbs by layering them in a cardboard box and placing newspaper between each layer. Avoid allowing the bulbs to come into contact.
Store away from cold temperatures and direct sunlight in a cool, dry area. About once a month, check the hardness of the bulbs and discard any that have turned mushy.
Keep the bulbs in a cool, dry place until they are planted in order to prevent breaking dormancy. So it makes sense to move them from the garage to a cool spot in your basement in the spring. The bulbs could even be housed in a separate refrigerator that can be kept chilly.
Can you grow alliums from seed?
After the foliage and blooms have faded, you can lift, divide, and replant clumps of older plants if they are getting too crowded.
There are numerous allium species that generate offsets, or young plants. You can lift the bulbs and separate the offsets when flowering is over and the leaves have stopped growing. Either directly plant them in their ultimate locations, or let them grow outdoors in pots with grittier compost.
Some alliums (including Allium roseum, Allium sphaerocephalon, and Allium vineale) generate aerial bulbils in the flower head instead of flowers. These bulbils can be delicately taken out and divided. Planting the bulbils in wet, well-draining compost that is spaced 2.5 cm (1 in) apart and covered with a 1 cm (3/8 in) layer of compost is possible. They will not achieve blossoming size for a few of years.
Alliums can be propagated by seed, however hybrids won’t ‘come true’ (i.e., they can differ in colour and shape from the parents) with this technique. Ripe seeds should be sown as soon as possible. Put the seeds into grit-filled compost trays and top with 5 mm of grit. Put the containers in a shaded area of the yard. Alternately, keep seeds chilled and plant them in the spring at about 13C. (55F). Most seeds ought to germinate in about a month. It will grow to flowering size over a number of years.
How can I grow more allium bulbs?
When the blooms on your Globemaster allium start to get smaller and the plant starts to seem crowded, or whenever you wish to start new plants, divide the plant. Wait until the leaves start to fall from the trees in the autumn because the green tops absorb sunlight, which gives the bulbs vitality to last another year of blooming. Dig an allium clump, being careful not to cut the bulbs with the shovel’s tip. Plant the bulblets in fertile, well-draining soil after separating the individual bulbs.
Can bulbs be forced all year long?
Until they begin to develop leaves, keep your planted bulbs in a cool location between 50 to 60 degrees F (10-60 C). As a result, the flower stalk will grow more compact and be less prone to topple over. The flower bulbs can be moved to a warmer place after leaves start to develop. They favour direct, bright light. Make careful to regularly water your forced bulbs. Moisture must always be present for the roots.
Cut off the spent flowers from your forced bulbs once they have finished blooming and put them outside. Here are instructions for planting forced bulbs outdoors. The amaryllis is the single exception to this rule because it cannot live outdoors all year. However, you can make an amaryllis bloom again. Find out here how to get an amaryllis to bloom again.
After a forced bulb blooms, what should you do with it?
I really wanted to say, in a loud voice, “I typed Heck, absolutely! in response to your query, but I later deleted and retyped it. In order to better understand, it should be noted that while many seasonal and gifted bulbs can be successfully transplanted and will continue to be presents that keep on giving, there are a few outliers that aren’t worth the trouble. Sadly, they are typically tulips. So let me explain.
Encouragement of bulbs to forego their natural schedule and bloom inside earlier is referred to as “forcing. Some bulbs may need years to recover from the unnatural stress they experienced during this procedure. Small bulbs that easily naturalise or proliferate in the garden are typically the most durable candidates worth conserving. Examples include crocus, snowdrops, scilla, and grape hyacinth (Muscari). Anything produced in water should be thrown into the compost bin, but larger hyacinth and daffodil bulbs that have been cultivated in soil are worth the effort. They’ve finished. I am really going through the recovery process with a tray of abandoned blue muscari and tiny ‘TteTte’ daffodil bulbs that I inherited from a friend’s setup at a professional garden show. These passed-down bulbs won’t produce flowers next spring, but if buds do develop, I will (with considerable difficulty) cut them off so the bulbs have a full growth season to recover.
Under ideal conditions, many tulip varieties are unreliable re-bloomers, and some simply never recover from being forced to bloom once more. With wilder species tulips and their hybrids, or in cooler locations with a long spring, you’ll have the best chance of success.
To Preserve Every Forced Bulb:
- Cut off any dead flowers, but keep the foliage whole. Place the containers in a bright window inside or in a covered area outside, and keep watering them as usual.
- Once the leaves have wilted and died, let the soil dry completely. Place the pots in a shed, garage, or basement that is cold and dry. Alternately, remove the bulbs from the soil, remove any dead foliage, and place them in a paper or mesh bag filled with bone-dry coir (coconut fibre), or vermiculite if you have it. This will allow the bulbs to go entirely dormant.
- Plant outside in the fall and sprinkle with greensand and rock phosphate.
Can dried-up bulbs re-grow?
It is frequently questioned whether or not the bulbs are too old to be planted, whether a gardener just so happens to uncover some neglected bulbs in a garage or shed, receives some bulbs from a friend, or purchases an outdated package of bulbs. I’ve done some study on bulbs and have come across some useful material that should be helpful in any bulb-related circumstance.
Can aged bulbs therefore be planted? Yes, you should be able to plant the bulb successfully if it is still firm and plump. However, the bulb should not be planted and can be thrown out if it smells terrible because it is rotting, is soft or mushy, or is dry and shrivelled up.
Perhaps you find that some of your bulbs are still in fine condition while others are not. Continue reading to find out more about bulbs in general, how to inspect them in further depth, and how to store them so they remain in good condition for planting.
