Allium Plant – How To Grow Alliums In Your Flower Garden
By Becca Badgett, Co-author of How to Grow an EMERGENCY Garden
Allium plant is related to the garden onion, but don?t let this deter you from planting it. In fact, minimal allium care and a show of large blooms are just a couple reasons to include them. Get more info here.
The majority of alliums are bulb-forming however, there is a handful that grows from rhizomes, the way common chives (Allium schoenoprasum) do. These may never form any kind of bulb. Allium leaves tend to be long and strappy. Some—like the cork-screw allium—remain attractive all season, with a blue-green color that complements the flowers. Most early blooming alliums have foliage that tends to die-back early, as the plants go dormant for the summer.
The flowers form in clusters and are best known in the round pom-pom form, but they can be star-shaped, cup-shaped, semi-circular, or pendulous. There's a good amount of variety in allium plants. Drumstick alliums only grow about one foot tall with 1-inch flower heads, while giant 'Globemaster' can top 4 feet in height and sport huge globes of 8- to 10-inch flower heads.
Most allium bulbs grow quickly, and they bloom in the spring or early summer after the earliest spring bulbs have faded. However, there are a few varieties that bloom later in the season, even well into fall.
The plump, round shape of the flowers looks charming poking through other plants, whether low-growing mats such as hardy geraniums or shrubby roses. The purple color is a great asset that complements most other late spring flowers, from peonies to iris to catmint. The shape also works well with other medium height plants, like foxglove or monarda.
The big drawback to early-blooming alliums is how their leaves can start to go downhill, even before the plants have flowered. If at all possible, try to hide the foliage behind a denser plant daylilies work well for this.
For the best flowering and healthiest plants, place your alliums in a site that gets a full day of sun. They will grow in partial shade, but since so many of them have short seasons, give them as much sun as you can.
Alliums prefer a soil pH that is slightly acidic, at around 5.5 to 6.5. However, how well the soil drains is far more important than soil pH. Do not let the bulbs sit in damp soil, especially during their dormant season. If they remain wet for too long, they will rot. Adding a good amount of organic matter to the soil before planting will improve draining while allowing enough water to reach the bulbs.
Alliums need infrequent watering, and if it rains often that should do the trick. Otherwise, watering every three to five days is fine.
Temperature and Humidity
Hardiness depends on the variety being grown and the growing conditions, but most alliums will do well in USDA hardiness zones 4-10.
If you regularly amend your soil, you may not need to feed them at all. However, if your soil is less than ideal, a little balanced fertilizer as they start to set flowers will help them replenish all the energy they use blooming.
Planting Allium Seeds
Scoop a soil-less seeding mix into a seed-starting tray or flat. A soil-less mix will contain peat moss, vermiculite or perlite, sand and sometimes a little lime and compost. For best results, make sure the mix is also sterilized.
Sow the allium seeds generously across the surface of the mix in the tray or flat. You can pinch a bunch of seeds together between your thumb and index finger, or if you prefer, use a pair of tweezers or forceps for a more accurate planting. Space the allium seeds 1/4 inch to 1/2 inch apart.
- Place the allium seeds onto paper towels to air dry for about one day.
- A soil-less mix will contain peat moss, vermiculite or perlite, sand and sometimes a little lime and compost.
Press the allium seeds about 1/8 of an inch into the seeding mix using a spoon or a small piece of wood.
Put the tray where it will remain at approximately 70 degrees F for three weeks. Check on the tray at least once a day. Do not over-water the allium seeds so they become sodden wet, but keep them moist by misting the seeding mix with a fine mist of water as needed.
Transfer the tray after three weeks has passed and place it in a location where the temperature will not go below 50 degrees F or above 70 degrees F. Leave the tray in this location during the remainder of the germination period. Depending on what variety of allium you are growing, germination can begin in about one year.
According to the University of Maryland Fact Sheet on Alliums, most allium grown from seed will begin flowering in about two to three years.
There are dozens of varieties in cultivation here are some of the best:The Purple Sensation allium bridges the gap between spring and early summer-flowering perennials.
Purple Sensation: the 2? to 4? diameter purple globes bloom in early June, right after the late tulips. Purple Sensation's sturdy stems rise 24? to 30? high, so the flowers appear to float above the foliage of newly emerging perennials.
Globemaster and Gladiator: The tallest and most architectural alliums have huge, globe-shaped flowerheads on 3- to 4-foot stems. Bloom time is early to mid-June. A group of deep-purple Globemaster or Gladiator alliums is a real eye-catcher, especially when planted with white or pink peonies, delphiniums or tall bearded iris. The white-flowering Mount Everest is a bit shorter and looks sharp in front of shrubs with deep-green or burgundy foliage or rising out of a groundcover of periwinkle (Vinca minor).
Ozawa allium (Allium thunbergii 'Ozawa'): A tidy, clump-forming plant that grows 18? to 20? high. Among the last of the perennials to bloom, its flowers often don't open until late September or October. Bees love it. Another late-bloomer that flowers in autumn. Its pink flowers pair well with coreopsis, gaillardia, solidago and other fall flowers.
Corkscrew allium: Drought-tolerant corkscrew allium (Allium senescens ssp. montanum var. glaucum) makes a good edging plant in the dry soil at the top of my stone retaining wall. Its blue-green leaves twist like loose corkscrews. Bloom time is late summer.Schubert alliums at the Chelsea Flower Show in England.
Schubert allium (Allium schubertii): Quite dramatic, though only 8? tall . Its foot-wide umbels look like an exploding pink fireworks display. Sure to elicit comments from garden visitors. Seed heads add interest for a month or more after blooms fade.The drumstick allium is a bit floppy, so plant it among other perennials that can provide support.
Drumstick allium (Allium sphaerocephalon): Blooms in early July, a couple weeks after Purple Sensation. Not as erect and orderly as Purple Sensation, but in the right place (where casual is OK), the two-toned, burgundy-green heads are fantastic. Great with ornamental grasses.This yellow allium (Allium flavum) is a good choice for rock gardens
Yellow allium (Allium flavum): A midsummer-blooming favorite that is well-suited to rock gardens. Over a 10-day period, the cluster of florets slowly emerges and becomes an exuberant display of color. Related species available in yellow, pink and white, 12? to 24? high.
