alliums

Filed Under uncategorized 

I’m not so crazy about the white alliums, like A. rosenbachianum ‘Album’ with its 5-inch loose heads on 3-foot stems, as part of my beds, but I include some in the long row of ornamental onions I planted in my vegetable garden for cutting. Very showy, very long-lasting. At Martha Stewart my colleagues recommended putting a drop of bleach in the water to prevent the onion-y, funky scent when using alliums as cuts. Other great allium traits: built-in animal resistance, unlike most bulbs, and the fact that because they are so linear (taking up almost no room at ground level) you can fit more more more anywhere. And I do.

    I adore alliums, but they are so expensive to purchase from a bulb catalog! My mother-in-law swears that some of her beautiful alliums are leeks that she planted long ago. Could this be true?

    Hello, Liesl. I know that many onions and related edible alliums will overwinter and even sow new babies around, but I don’t think you could mistake one for a very showy ornamental type, certainly not the large globes of vivid purple. I had to look around on the web for a photo of a leek blossom to share to see if this is what she has.
    As for the cost of alliums, many will multiply from seed they sow if the heads are left in place to ripen, so it’s good to inquire for your conditions/zone which ones colonize.

    Thanks Margaret! Based on the photo, I believe my mother-in-law is correct! Her leek blossoms are 5-6 feet tall, a light pinky purple color, with fist sized globes and are in full bloom by the end of July in Eugene Oregon. They put on quite a show!

    How long should I keep the faded globemaster blooms before cutting back?

    As long as you like the way they look, leave them. When that’s not the case, cut them down at the base. Alliums will tend to self-sow new babies around if allowed to set seed in place, so consider whether you do or don’t want all the young ones.
