It’s fascinating to grow cultivars and see what you get even though the seeds won’t be true to type.
Can allium seeds be preserved?
Excellent bulb plants for perennial gardens are ornamental alliums. They are attractive onions, which come in a variety of species and cultivars.
Their sizes range from the smaller “Allium sphaerocephalon, a smaller allium, to Allium giganteum, a larger allium.
The majority of people grow alliums from bulbs since it is relatively simple to do so.
However, you can also start new plants from seeds if you are raising alliums that produce seeds. Increasing the number of allium plants in your garden is simple and affordable.
However, not all attractive allium plants will, and some will only produce a small amount.
A few varieties of allium are sterile and won’t set seed. In the case of cultivars like Allium “Globe Master” and Allium “Mount Everest,” this is true.
Some cultivars, like Allium, produce a lot of seeds “Allium christophii, also known as the Star of Persia, and Purple Sensation
The seeds from alliums that produce seeds can be kept, planted, and grow to produce more allium seedlings for the garden.
Is It Worth Growing Alliums From Seed?
If you want to increase your allium stock, it is definitely worth it to grow alliums from seed.
Remember that some allium bulbs, particularly the larger types, can be rather expensive.
Therefore, gathering some allium seed will ultimately save you money if you have a larger cultivar that produces seed and wish to grow your allium stock.
It’s crucial to understand that hybrids won’t be true to the parent plant, and that the new seedlings may have differences in size, form, and color.
How are allium seed heads preserved?
I have an obsession with ornamental alliums. I keep growing more of them even though I now have around a dozen distinct varieties in my garden. Alliums are not only stunning to look at, but they are also long-blooming, pollinator-friendly, and appear to be immune to disease and pests, even deer.
And if that’s not enough, alliums’ seed heads are yet another reason to adore them. The seed heads of these late spring/early summer flowers can be an equally alluring lure after they have faded. They provide unique forms and textures to the yard and summer flower arrangements and many of them will survive for months. Continue reading to discover how to maximize the use of these eye-catching seed heads.
Use Allium Seed Heads in Fresh Arrangements
While they are still green, the seed heads can be clipped and added to bouquets of fresh flowers. Homegrown bouquets are given a distinct glitter by their color, shape, and texture. For this, Allium Purple Sensation works best.
Leave Seed Heads Right in the Garden
The seed heads can be left in the garden, where people will continue to be intrigued by their unique textures and shapes. The Globemaster and Gladiator alliums, which have sturdy, robust stems, are the ones that I find last the longest. Allium Christophiii’s seed heads, however, also persist for a long time. They may continue to look nice into August in a dry summer.
Paint the Dried Seed Heads
Another choice is to paint the seed heads once they have completely dried. Last year, I dried some Gladiator seed heads and used gold spray paint to embellish them. They emerged with a little bronzer appearance than gold. I might attempt silver paint this year.
The dried seed heads have also been painted glossy white and utilized as wedding decorations by me. The Gladiators are those displayed below.
Here’s a way for drying allium seed heads so you can paint them or just display them inside. When the seed heads are dry but before the seed capsules start to open and release the seeds, they should be painted or treated with a clear fixative. You can maintain the starburst effect and reduce the amount of seeds you need to sweep up by placing the seeds inside the capsules at the end of each “stem.”
The enlarged seed capsules are visible in the photo below, even though the seed head is not yet dry enough to paint.

Mid- to late-fall is the ideal time to plant decorative alliums. Orders are accepted starting in May, and bulbs are shipped from early September through mid-November. The only way to guarantee you’ll get the variety you desire is to place your order early. Our entire collection is available to view HERE.
Are allium bulbs formed from the seeds?
The growing requirements for these relatives of common onions are the same whether you are growing alliums for their eye-catching, globular flowers, like the Star of Persia (Allium christophii or A. albopilosum), or for their flavorful, pungent bulbs, like leeks (A. ameloprasum) or chives (A. schoenoprasum). Depending on the variety, both types of alliums can be grown in USDA hardiness zones 3 to 11, producing edible bulbs or blossoms in the spring, summer, or fall before withering away in the winter and regrowing the following year.
How are allium seed heads dried?
By planting fall bulbs for spring blooms, we are already thinking ahead for the garden of the next year. Alliums are among our favorite bulbs to plant in the fall because they promise to produce enormous, eye-catching flowers. Because of their extraordinary height, they can be used in formal or casual gardens as well as naturalized landscapes. They are whimsical yet dignified. Additionally incredibly adaptable and durable, alliums are perfect for year-round decorative use. Continue reading for our instructions to growing, drying, and using these garden giants as decorations.
Planting Select a planting place with well-drained soil and full sun as soon as the leaves start to fall. This will help your alliums grow stronger stems. These huge bulbs, which can rot if exposed to too much moisture, require good soil drainage. For each bulb, dig a hole that is 2-3 times as deep as the bulb’s height, measured from the bottom of the bulb. Place the bulb in the ground with the pointed end facing up, completely cover it with dirt, and give it a good watering to help it settle. If you’re planting several bulbs, make the holes about 6 to 8″ apart. In the fall and winter, roots will begin to grow, and in the spring, leaves and flowers will appear.
Find a spot for alliums where they may tower over other plants without getting blown over by the wind. The majority of allium stems are robust and sturdy, but as they get older, they might break and become untidy. Never allow the stake extend past the ball if you decide to stake an allium as it grows. Alliums can benefit from having mounding plants around them, such as hardy geranium and nepeta, to help hide the leaves as it turns yellow later in the season.
Drying The majority of allium cultivars bloom in the late spring and early summer, but if they are left in situ, they can keep the garden going into the fall and even the winter, becoming a tawny gold. Their pointed seedheads, however, can also be carried inside and dried for ornamental purposes. Pick a drying location first when you’re prepared to take your alliums from the garden. A pantry or closet may be the best location because they are cool, dark, have good ventilation, and have low moisture levels. To suspend the allium stems, run a taut strand of twine or wire across the area.
When the seedheads are fully developed and dry, harvest them, leaving the stems intact. Make bundles of two or three stems using rubber bands after trimming any extra leaves. Your alliums can be suspended separately if they are quite large. The seedheads should dry for three to six weeks after you attach the bundles to your drying line (we like to use an unfolded paperclip for this).
Decorating Once dried, seedheads make amusing embellishments for both the home and yard. When placed within a glass cloche with other preserved flora, they develop into a natural collection. Tall stems provide new plantings, like a hanging basket or a barrel of autumn grasses, architectural interest. We’ll also add dried alliums to wreaths and evergreen trees as the holidays get near for a botanical Christmas.
Following flowering, what should you do with alliums?
Taller people can need assistance when exposed. After the flowers have faded, let the plant with them until they disintegrate because they make for wonderful winter interest. Some gardeners collect the seedheads and dry them so they can be used as home decor.
Allium bulbs can stay in the garden for multiple seasons. When planting new plants, try to keep in mind where you already put bulbs to prevent damaging those areas.
How to propagate alliums
In a few years, allium bulbs will grow in number. You may occasionally see the white bulbs being pushed out of the ground. Carefully pull the bulbs and gently peel out the offsets in late autumn or very early spring to replant them directly into the ground.
Allium can be grown from seed by leaving the flowerheads on the plant and harvesting the ripe seed to sow right away. Keep in mind that starting alliums from seed requires patience because it takes years to produce a flowering plant.
Growing alliums: pests and problem solving
A fungus called allium white rot prevents the growth of other alliums and onions. Clear and burn the infected plant material, and stay away from growing alliums in the same spot for at least five years, to prevent recurring infections.
Alliums have a tendency to outgrow their surroundings. Learn how to control the amount of alliums growing in a border in this Gardeners’ World video:
Alliums can be cultivated from seed heads.
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 color 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 are seed pods preserved?
I freely scattered the annual poppies (Papaver somniferum), which an elderly acquaintance had given me, in a brand-new bed of perennials. Due to the fact that I had sown a large number of seeds, they did well the first year. But by the second year, the perennials had filled in and there was nowhere for the poppies to grow. When I noticed a few plants were struggling, I scavenged them and unsuccessfully transplanted them to open sections of my garden. Poppies should be relocated in a shovelful of soil, with their roots intact and undamaged. The bare-rooted seedlings I had picked up survived for a couple of weeks before deteriorating and dying. When that happened, my friend had already departed for the vast garden in the sky, and the new owner had returned the once-glorious gardens to their original state of grass.
I figured I could just buy some seeds, no problem. It turned out that her garden’s decades of natural selection produced those gorgeous, frilly blossoms. They had stabilized into a kind that consistently reproduced themselves year after year after years of self-sowing with my friend cutting away the plants with single-petaled flowers or odd hues. Before I understood the terrible truth, I spent more money than I like to confess purchasing seeds from every vendor that was open for business. She didn’t have her variety of poppies available for sale. In order to create something that resembled my friend’s ruffled beauties, I had to start from scratch and save seed from the most beautiful poppies. I can now smugly claim to have my own kind of annual pink poppies, which I fervently collect seed from year after year to keep alive a variety I call the “Sally” variety.
One of those pursuits that makes me feel fortunate is seed collection. I take as much pleasure as Midas in counting my riches of coreopsis (Coreopsis lanceolata and other spp. ), calliopsis (Coreopsis tinctoria), hollyhocks (Alcea rosea), and moonflowers (Ipomoea alba), among other plants, as the seed supply spills out of the first, small envelopes into manila 8210s and Mason jars. I’ll have shelves stocked to the brim with the seeds for the following year’s garden by the time I’m done in the fall.
Start simply, with flowers
Even if you simply have a tiny bed to fill, packet costs can quickly pile up. A summer garden full of favorite flowers like mallows, petunias, marigolds, and others can be created the following year by spending a few minutes in the early fall shaking ripe seed into an envelope. These flowers will grow for nothing. By saving your own seeds, you can utilize your garden budget to make significant purchases other than plants, such as that teakwood dining set you’ve had your eye on.
All types of plants have seeds that can be saved. The easiest plants to grow are annuals because they produce the most seeds, but perennials and biennials are also totally feasible. However, certain plants aren’t worth collecting seeds from as they multiply considerably more quickly by division. I don’t play games with plants like showy evening primrose (Oenothera speciosa), bee balm (Monarda didyma), daylilies (Hemerocallis cvs.), irises (Iris spp.), or bee balm (Monarda didyma). I could start them from seed, but why bother? I have a solid start that is ready to be planted after a fast trowel stroke.
Before a few years ago, I never thought to save the seed from bulbs, but now I always do it. Particularly rewarding are little, early-spring bulbs like scillas (Scilla siberica) and snowdrops (Galanthus nivalis). I gathered seed and nurtured the tiny plants that emerged, planting them one by one in a steadily expanding area, and instead of waiting half a lifetime to have an ocean of blue scillas under my trees, I succeeded in doing it in five years.
I got the notion to start producing trees, bushes, and vines from seed thanks to birds. They “left the seeds of many of the plants in my forested front yard, from hawthorn to American holly (Ilex opaca) and virgin’s bower (Clematis virginiana) (Crataegus spp.). Although I appreciate the work of the birds, I prefer my plantings to be a little less haphazard, so I now go out and gather my own berries and seeds for woody plants.
The ideal plants for beginners are flowers because they typically don’t require any particular care in order for the seeds to grow. Self-seeding plants are ideal for practice, including cottage garden columbines (Aquilegia vulgaris), spider flowers, and California poppies (Eschscholzia californica).
Not every plant that is developed from seed resembles its parents. “Heritage seeds” are used to describe those who do. Some catalogs specialize in them, and more casually, backyard gardeners do as well. These plants always “come true from seed,” just like my friend’s pink poppies or the magnificent ivory-seeded sunflowers (Helianthus annuus ‘Tarahumara White’) created by Tarahumara Indians of the Southwest.
You’re sure to have pleasant surprises if you harvest seed from a variety of the species in your garden. A strangely striped, russet marigold that adorns my summer garden is one of my favorite garden flowers. It sprouted from a batch of seed I saved from a pricey named variety, and I slowly weeded out the errant seeds until it almost produced true offspring. Now I give out envelopes with the seeds, sure that the majority of the kids will resemble Mom Marigold, but also aware that friends may receive their own, equally wonderful surprises.
Gather seeds as they ripen
I keep an eye on the developing seeds as the blossoms start to fade. I cut off the seed heads when they begin to ripen and become brown. Normally, I cut one seed head at a time, gently. However, I remove seed heads in bulk and collect them in a brown paper bag or any other plastic container when seeds are maturing quickly, such as when my bank of Klondike Cosmos (Cosmos sulphureus) goes to seed. It’s not a lot of labor, if that makes sense. I walk the garden at least once a day and always have a supply of zip-top baggies in my pocket. It only takes a few minutes to remove seed heads or shake off the seeds.
I gather seed as it ripens throughout the growing season, which means I start in March when tiny bulbs are already ripening their plump pods and keep going until the garden is blackened by frost and the morning glories (Ipomoea tricolor and I. nil) are destroyed so that I can access the large clusters of pods. Late summer is when annuals and perennials bloom the most, at their peak. Fall is another major push, when I outrun the birds to gather berries from bushes and trees.
Similar to plucking tomatoes, experience teaches you when seeds are ready for collection and when they are not. However, since the seeds will continue to ripen off the plant once they reach a certain stage of growth, it is more like picking green tomatoes.
I’ve discovered that I can gather green seeds as long as I allow them continue to ripen in the seed head or pod, which most seeds will do even if they are taken from the plant. As the dill (Anethum graveolens) seed heads ripen, they break easily, and occasionally I miss my moment. So, as soon as the green seeds are a good size, I trim the flat heads and place the mature seeds on sheets of newspaper in the garage. The upright chambered seedpods on columbines, as well as annual poppies and spider flowers that self-sow too quickly, are clipped when they are still green.
Picking seed heads as soon as the petals start to fade is not advised. Wait until the seeds themselves, if any are visible, are at least fully developed and ripe. This is what I refer to as the “sunflower rule”: I wait to cut the heads off of these cheery blossoms until I can see the seeds have swelled. They never grow when I pick them when they’re still flat and withered. The same goes for seeds contained in pods, such as those of lupines (Lupinus spp.) and scarlet runner beans (Phaseolus coccineus): postpone harvesting until the pods get fat from the seeds inside. The living plant must provide the seeds with nutrition as they grow to their maximum size inside the seed coat.
Air-dry seed heads in shallow boxes
Once you have your seeds, choose a safe place for them to ripen and dry. Clean pizza boxes or shallow cardboard boxes used for shipping soft drinks are both suitable. Their low rims don’t obstruct the air flow that is necessary for drying. Newspaper is also useful, but because I’m clumsy, the boxes provide security from unintentionally sweeping seeds into the floor.
Seed heads and pods should be dispersed in a shallow layer with some room between them. To prevent the growth of mold, it is crucial to dry them as soon as possible. If you gather berries or other fruits, you should either remove the seeds before drying the fruit or dry the fruit completely and then dissect it later.
Shake the seeds into a paper bag or envelope when the pods and seed heads feel completely dry, which can take anywhere from a week to four weeks. The seeds should be sieved to eliminate chaff and other debris before being transferred to tiny envelopes or closed jars for storage. Remember to label them: Containers should be marked with the name of the plant and the date before being kept in a cool, dry location until planting time.
