Alliums are perfect choice to add architectural interest

Fall is the time to plant your allium bulbs

It all started with an experiment that didn’t quite work out. So, in the spirit of gardening, I added even more alliums this year to ensure next year is a success.

That’s the thing about alliums. Once you get a taste of them, there’s no going back.

My plan was to grow giant alliums in the fern garden where they could rise up above the massive Ostrich ferns and create outstanding architectural interest and a pop of coour among the ferns in late spring.

Alliums add architectural interest to every garden, whether formal or a more natural garden.

A very wet spring meant our ferns grew especially tall and, unlike most years, the ferns stood their ground and refused to fall. The result, our Purple Sensation alliums merely peeked out from between the ferns rather than rising above them.

But even the sight of the alliums peeking out among the ferns was enough to make me want to plant more this year. So this year we added taller alliums in both purple and white. I’m hoping for a great show next season.

We also added alliums in two other parts of the garden to ensure we get a great display.

If you are like me and have hesitated to plant alliums in your garden, make this the year you take the leap into this fascinating group of plants that are often referred to as ornamental onions.

These non-native bulbs, that tend to bloom a little later than daffodils and tulips, are part of a group of plants that include onions, garlic, leeks and shallots.

They are available in a range of sizes, colours and blooming times. In fact, if you plan properly, you can have them blooming from late spring through summer adding architectural interest to any garden.

They work both in formal gardens as well as more natural gardens including woodland gardens. Try to find a sunny spot for them for best results.

Like daffodils and tulips, fall is the ideal time to get allium bulbs in the ground for next spring. You can now find them in most stores, including many of the Big Box stores. Just realize that your choice in many of these Big Box stores is limited to the more common variety of allium bulbs. If you are looking for more interesting or unusual allium bulbs, you may have to check out better nurseries or mail-order firms like Brecks that offer a beautiful and comprehensive variety of alliums.

You can even purchase your allium bulbs from Amazon as well.

Get your orders in early to ensure you get the best quality and varieties.

What makes these bulbs especially great is that rodents tend to leave them alone. Deer, squirrels, chipmunks, voles even groundhogs express no interest in alliums. That’s probably because of their roots in the onion family.

The bulbs multiply in the ground creating denser clumps each year and the allium seeds can reseed in the garden adding more of these lovely plants to your landscape.

These easy-to-grow plants prefer full sun but do well in half-sun conditions in well-drained sandy soil. Extremely wet, poor draining soil is likely to create conditions for bulb rot in the garden.

Alliums stand out against a white wall.

Alliums can be a little more expensive than other bulbs, but once planted they last forever and after about three years the bulbs can be split to create even more plants.

Plant the allium bulbs about 7 inches under the ground – deeper than most bulbs – and about 8 inches apart.

If you are planting a lot of the bulbs, consider using a drill bit or auger especially made to create ideal holes for planting larger bulbs. This set of four augers from Amazon will meet the needs of even the most ardent bulb enthusiast.

Also, remember, pointy end of the bulb goes up.

One important point to consider is that the foliage of alliums often yellows before they bloom, so you might want to place another type of plant in front of the allium bulbs to cover up the yellowing foliage.

Alliums also make great cut flowers and their dry seed heads are perfect for arrangements. Consider painting them gold or silver for an especially nice touch in your arrangement.

There are so many alliums to consider for your garden, depending on size, colour and how adventurous you may want to be.

Brecks offers an incredible choice as well as mixed assortments that work well together. If you are serious about getting started with alliums check them out to give you a good grounding on what is available.

I picked up most of my bulbs from Costco this year, but you had to grab them early because they sold out quite quickly. My latest purchase from Costco were bags of Allium Nigrum Pink Jewel (10 to a bag), and the much larger Allium Gladiators (4 to a bag). I also picked up some white varieties of Alliums that we planted in the front garden.

Here are a sampling of alliums to consider for your gardens.

Best alliums for your zone-5 garden

Globe Master – has a huge bloom with purple flower heads as much as 5 inches across. Their blooms last a long time. Plant them in the middle or back off the border to hide the leaves. These alliums do not produce seed so it does not get weedy.

Mount Everest – White flower is 3-4 inches across but they are on a very long stem and grows to about 3.5-4 feet tall.

Purple Sensation – blooms at about 3 feet tall. Flowers are a little smaller than Globe Master but the colour is more intense. It is happy to re-seed itself around your garden.

Ivory Queen – Wide leaves and flowers at about six inches high with a lovely white creamy flower. Flower heads are two inches across and white. These smaller alliums are a great addition to the rock garden

Allium Christophii – Flowers at about 2.5 feet high with large flowers that can reach about 8 inches across. Will disperse seeds around the garden.

Allium fistulosum – flowers at about 2 ft high with white green flowers. Its stems are large thick and hollow. Will produce seeds but they always grow close to the mother plants.

Graceful Beauty – small allium that grows only 8 inches tall with nice white flowers. Leaves are grass like.

Allium atropurpureum – A very dark coloured allium that grows about 3-feet tall with smaller umbra reddish purple about 3 inches wide that flowers at 2.5 feet high. Acts almost like an ephemeral as its foliage disappears by mid July.

Allium Molly – grows to about 8 inches tall and flower is yellow with wide leaves. Hard to tell that it’s even an allium. It will seed around your garden a little bit but nothing too serious..

Allium Siculum – flowers at 2 feet tall. Flowers are unusual with an unusual colour. Striking plant for the garden with large strapping leaves.

Other alliums to consider

Allium sphaerocephalon – smaller allium 2 feet tall with a much smaller inflorescence.

Allium red mohican – Interesting colour of purple, white, cream with hints of yellow

Allium Firmament – purple flower head that grows to about 2 ft tall. Flowers are 4-5 inches wide

Allium Ping Pong – Grows to about 2-feet tall with a 3-inch flower

June-July bloomers

Allium nigrum silver spring – lovely allium growing to between 2-3 ft tall with 4-inch wide umbrels that have a blueberry/raspberry colour to them. Infloresence is one of the most beautiful yet still subtle of the alliums.

Allium chloranthum (Yellow Fantasy) – Grows 14-16 inches high with a flower that is only about 2 inches wide but has a lovely yellow colour

Check out Brecks for mixes

Allium summer drummer – very tall 4-5 feet tall reddish purple with 6-8-inch wide umbels. Late bloomer in July and August.

Planting for flower photography

The vision in my mind was brilliant, despite not working out quite so perfectly in the end. However, I still consider the experiment successful and expect to continue photographing the combination of purple alliums growing up through a sea of green Ostrich ferns.

As mentioned earlier in this post, our wet spring caused our ferns to grow taller than ever and fail to fall like they usually do. The result was alliums peeking out through tall upright ferns rather than the lovely purple flowers rising above and floating over the ferns.

When the alliums finally began to appear in late spring, I took the opportunity to document the scene.

Most of the images below were shot with the original Lensbaby composer lens to impart a more creative touch to the images. The lens allows the photographer to create out-of-focus areas in the image while maintaining sharp focus areas where the photographer chooses.

Below are just a few of the images from the Lensbaby composer.
