How to Grow Alliums: The Ornamental Onion

One bulb that is becoming more and more in demand is the Allium. There are TALL ones (3’–4’), TINY ones (4”–6”), and many heights in between. There are many colors of Allium flowers from which to choose: white, pink, blue, lavender, purple and yellow. Most Allium flowers are roundish; some are filled with florets and others are loosely formed so you can almost see through them. Some of the flowers are as small as a ping-pong ball; others are baseball-sized; some flowers are softball-sized and there is one that is volleyball or basketball-sized, depending on the nutrients in the soil and available moisture.

All Alliums don’t bloom at the same time but generally bloom with the group that we have nicknamed ‘Bridge Flowers’—the ones that begin blooming when the late daffodils and tulips are beginning to fade with other Alliums blooming when the summer lilies begin to put on their show—bridging the gap between the ‘Spring Splash’ and the ‘Summer Show.’

This image was taken in our garden and has many of our nicknamed ‘Bridge Flowers.’ The ones that are roundish are Alliums. Of course, these are not all of them because, as we said before, they don’t all bloom at the same time.

Alliums grow best when planted in well-drained soil. When they have finished blooming and go dormant (sleeping) during the mid-late summer months, they need to be in a DRY, DRY, DRY garden. Mindless irrigation will rot their bulbs. Sometimes we have a lot of rain in the summer, so we try to plant drought-tolerant plants in the same bed with the Alliums in hopes that they will use up all the moisture in the garden, keeping the Alliums dry.

Alliums are pest tolerant—most animals are not fond of the taste of onions. However, when  animals are hungry, they will eat what they don’t like to stay alive. We suggest a product called PLANTSKYYD to help deter the underground bulb monsters’, the voles from munching on your Alliums.

Alliums make great cut flowers. If the onion smell is unpleasant, one drop of Clorox in the water makes that smell disappear.

Once the Allium flowers die, that does not have to be the end of their story—at least for some types. The larger ones in the image above, which look very regal and statuesque when they are in bloom, like Allium ‘Ambassador,’ continue to be statuesque even when their flowers have died. They continue to decorate your garden like a piece of sculpture. The red one on the right is not the tallest, but it is the one with the largest flower, Allium schubertii.

We had so much fun spray painting some of their dried Allium flowers with various bright colors and putting them in our gardens. Visitors wanted to know what the “new summer bulb” flowers were…TOO FUN! Once dried, the Allium’s stems are hollow, so a small piece of wire or a small bamboo stake in that hollow stem helps stick them in the ground. Looking at flowers makes people happy. Redoing these awesome flowers made ALL of us laugh out loud as we painted!

Alliums have flowers that “keep on giving,” right through the end of the year! Spray painting their dried flowers gold, silver, red, or any other color you choose gives the Christmas tree a totally different look. Those spray-painted flowers make great gifts as well.

Children get a thrill decorating Christmas trees! Just think how they will feel growing beautiful Alliums, enjoying their flowers in the spring, painting them for the summer garden and saving a few to decorate your tree. This is just one more way to play in your garden!
