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.
Allium dries efficiently?
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 are allium heads dried in the UK?
Sarah demonstrates her favorite allium kinds in this video while they are drying and prepared for spraying as holiday decorations.
In this garden, the Oast Garden, alliums bloom beautifully in May and appear stunning. When “Purple Sensation” self-seeds, it reverts to this Allium hollandicum species, which is lovely and just a little bit paler mauve than “Purple Sensation.”
Because it feels more like fall by August and I don’t want it to feel like autumn in July, I personally don’t like seeing the seed pods in the garden. All of these seed pods from the border will simply be removed since I want the garden to retain its vibrant color and juice. They will not be added to the compost pile. In order for them to dry out completely, we keep them for a few weeks. After that, I spray them with silver paint to add them to the Christmas tree, and they look amazing.
The smallest allium is “Purple Sensation,” but in June, you may also get “Cristophii,” which is a bit bigger and also dries well, and “Schubertii,” which is enormous, sprays magnificently, and is the ideal allium for the top of your Christmas tree.
The ones we’ve previously selected are still a little bit green, but as soon as they’ve completely dried out and lost all of their green color, they will be ideal for spring. Additionally, we have nigella pods that are gorgeous when turned into chains for a Christmas tree and are currently drying. Simply run wire through them to create these lovely chains for a Christmas tree.
We then use angelica for large decorations. They expel their seeds, leaving behind these lovely stalks that resemble globes and look amazing when sprayed.
The Allium schubertii is the most magnificent allium; it is enormous and looks like it has sprayed silver on top of a Christmas tree. It’s ideal to harvest now or even when conditions are a little dry, but don’t wait too long since once the winds of fall arrive, they are very easily blown away and crushed. Therefore, harvest them when they are still somewhat green and juicy, hang them upside down in a barn or your potting shed, and they will be ready for Christmas.
Because you don’t want to breathe in the paint’s chemicals, you should spray them outside. They were simply placed on a huge outdoor table covered with tons of newspaper. Simply spray them while wearing a black trash bag or an apron that you don’t mind having some silver paint on. It should coat them rather equally if I spray them, let them dry for a half-hour, turn them about, spray them again, let them dry for a half-hour, and do the same. Then all you have to do is leave them, and they will look lovely on the Christmas tree.
I adore alliums because they allow you to appreciate the beauty and three-dimensionality of the entire arrangement, as opposed to only placing ornaments at the top or even halfway down the stems of a Christmas tree, which results in something that resembles a pyramid or triangle. The greatest option for that is an allium, both little and large varieties like the schubertii.
What should you do with alliums once the flowering is over?
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:
How is Allium Christophii dried?
Pick the seed heads when they are totally ripe but before they begin to deteriorate and weather, after allowing some blossoms to go to seed. Poppies and Nigella mature seed heads will rattle, Scabiosa ‘Ping Pong’ will feel papery, and Allium heads and stems will have started to lose their color. They must be harvested on a dry day because any moisture will make them moldy. Pick plants with the longest stems you can (you can cut them to size later). Hang the stems upside down in a warm, dry location, such a shed or airing cupboard, by tying them together in little bunches (or just one for large Alliums). They must be ready in two to three weeks.
Do you remove the alliums’ heads?
Alliums are drought-tolerant, thus it’s typically not essential to water plants that are rooted in the ground. Summer irrigation is not preferred by plants since it could lead to bulb rot. Alliums planted in containers will require routine watering, but watch out for soggy compost.
Overwintering
Winter cold can be more damaging to plants in pots. to ensure their winter survival
- Place containers in a protected area.
- Place them in the lee of a wall, within a cold frame, or a greenhouse to provide them with some protection from the winter rain.
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 is allium cut?
Because flowers will continue to open in the vase, a procedure that lengthens the vase life of flowers, the standard recommendation to home allium growers is to cut them when flower heads are one-fourth to one-half open. Allium aflatunense, also known as the Persian onion, Allium caeruleum, popularly known as the blue globe onion, and Allium sphaerocephalon, commonly known as the drumstick allium or round-headed garlic, are best cut in the late spring or early summer when the blossoms are half-to-full open. Drumstick and blue globe alliums are categorized as summer bloomers.
- To avoid crushing or otherwise harming stems, cut alliums with a razor or a knife that is extremely sharp.
- Because flowers will continue to open in the vase, a procedure that lengthens the vase life of flowers, the standard recommendation to home allium growers is to cut them when flower heads are one-fourth to one-half open.
Can flowers be dried in a closet airer?
Lavender bunches, wheat, and lovely delphinium bunches are a few examples of our complete bunches. Some of these are grown and dried in the UK, while others, like the gypsophila and sea lavender bunches (see image below), are produced in-house.
Air drying at home
This approach makes it simple to dry plant material at home, while the outcomes can vary and experimenting is always advised. Gather a few of your favorite stems, tie them loosely together, and hang them upside down in an area with sufficient airflow. A garage or even an open porch can be effective, though the procedure might take longer. The airing cupboard produces quick results. Although the blossoms dry rapidly in a bright greenhouse, the strong sunshine may cause some of their vibrant colors to fade, making this method less ideal.
Lay some blossoms flat on some kitchen paper and place them next to a radiator for a day or two to dry out to create natural confetti or potpourri at home.
The usage of ovens is a substitute at home. It is possible to dry fruit slices and flat objects overnight in a low oven (30C) by arranging blossoms on a baking pan. Books are also available on the topic of combining a desiccant like silica sand with a microwave oven to dry plants.
On Ruth’s blog, driedflowercraft.co.uk, you can find a lot more advice and information about drying plant material at home.
Freeze drying and confetti petals
For delicate blossoms, freeze drying is a technique used to avoid possible wrinkling or color loss from air drying. Rose petals for pricey confetti are sometimes made from freeze-dried roses.
It calls for pricey specialized equipment yet yields a bloom that appears just as fresh as the day it was harvested. Only quality petals are utilized because it is an expensive process and each bloom receives practically unique care. The cost of purchasing blooms prepared in this manner is high, but it may be worthwhile if they will be closely seen, such as in a wedding table design.
The petals are carefully reduced to temperatures well below freezing while being held under vacuum to begin the freeze drying process. The water evaporating from the petals freezes onto a specially cooled plate and is removed as the temperature is gradually raised again (over a few days).
Given the exorbitant price, there was insufficient demand for this kind of petal, thus we no longer sell it.
Liquid preservation of confetti petals
Technically speaking, since the plant material is still “wet,” this is not a drying procedure. Any water in the stems must be replaced during the procedure with a mixture of glycerine preservative and dye. This produces a flexible blossom rather than a brittle one. It implies that color can be picked out precisely. But because of the ingredients, there is a tiny danger of stains if the dye is utilized. For roses and other types of confetti petals, this preservation method is frequently employed.
We keep a few preserved goods on hand. Hydrangea petals make wonderful natural petal confetti. In the image up top, ivory delphinium petals and duck egg blue hydrangea petals are combined. The petals of the delphinium were air-dried in the UK. Whole hydrangea heads, preserved gypsophila, and preserved eucalyptus bunches are also offered seasonally.
