We’re already planning ahead for next year’s garden by planting fall bulbs for springtime flowers. 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.
How well do allium blossoms dry?
Bulb-born ornamental alliums sprout sturdy, tall stems that can eventually reach heights of three feet. Given that the allium genus includes chives, garlic, onions, and shallots, it makes reasonable that some flowers, which can swell to the size of baseballs, are alternately compared to onion flowers. Others have a puffy, purple pom-pom appearance.
There are lots of options, but a few in particular would produce gorgeous dried allium heads. These include “Purple Sensation,” which according to Gardener’s Supply Company produces purple “globes,” and “Gladiator,” which has deep purple blossoms that can reach a height of 4 feet.
Other eye-catching varieties include the Ozawa allium (Allium thunbergii ‘Ozawa’), a late bloomer with purple-pink flowers; the ‘Corkscrew’ (Allium senescens ssp. montanum var. glaucum), so named because its leaves resemble miniature corkscrews; the ‘Schubert’ (Allium schubertii), a dramatic flower whose blooms
How do I dispose of my old allium blooms?
The foliage of the allium often appears at least a month before the flowers do. Some species’ foliage starts to turn yellow and die off before the flowers are fully open. Plant the bulbs with other plants that will obscure the wilting foliage to help mask it. Alliums do well with hosta, astilbe, and perennial geranium.
When your alliums are blooming, you may anticipate seeing a lot of pollinators. Any type of habitat garden will benefit greatly from the inclusion of these bulbs.
Like their relatives in the vegetable garden, alliums hardly ever have insect or disease problems. Rarely do bothersome rats and deer show any interest.
Most alliums are perennial plants. They will typically bloom again if the species you are planting is winter hardy and the bulbs are suitable to the growing environment in your yard.
Caring for Alliums After They Flower
Allium wasted flower heads can be removed or left in situ once flowering is over. The seed heads are viewed as an intriguing decorative element by many gardeners. Depending on your environment, they may persist far into the beginning of the fall.
Large-headed alliums like Schubertii and Globemaster hardly ever produce viable seeds. Purple Sensation and drumstick alliums will reseed if the conditions are favorable. Simply remove the seed heads after the flowers have faded and before the seeds develop to prevent a carpet of tiny volunteers.
There are herbaceous alliums as well as alliums that grow from bulbs, including varieties like Millennium and Summer Beauty. These plants have a big root system and come back every year to blossom.
Alliums that emerge from bulbs require their foliage in order to generate energy for the blossoms of the next year. Therefore, it’s crucial to let these plants die back organically. The leaves may typically be removed with a simple tug once it has turned yellow and dried. Trim off the wasted blooms from herbaceous alliums with hedge shears or scissors once they have stopped blooming. This will maintain the plants’ clean appearance and might promote a second flush of blossoms.
You Just Added to Your Wheelbarrow
The contents of your wheelbarrow will be emptied and added back to inventory if you leave it unattended for longer than an hour. Place your order knowing that you can modify it before shipping if you haven’t made up your mind.
