When it comes to picking the perfect spot for your ornamental onions, it’s not exactly a “one size fits all” situation. While most varieties love soaking up the sun in dry soil, there are a couple of notable exceptions you’ll want to keep in mind.
Different Varieties, Different Needs
Because there are so many different types of Allium out there, it’s hard to point to one single spot in your garden and say it’s perfect for every single one. However, the good news is that the majority of them share very similar preferences when it’s time to get them in the ground. When your Allium is happy with its home, it’ll let you know by showing off with sturdy growth and a stunning explosion of blooms.
The Ideal Growing Conditions
For most ornamental onions, the “sweet spot” is a location that is sunny, warm, and on the drier side. If you stick to that rule of thumb, you’re usually golden.
The Sunnier, the Better
Most varieties are total sun-worshippers. When planting, try to find a spot that gets plenty of sunlight throughout the day. You’ll definitely want to steer clear of full-shade areas, as these plants really need that light to thrive.
Loose and Well-Draining Soil
In addition to sunshine, most Alliums prefer soil that is relatively dry and drains well. If your garden has heavy or clay-like soil, don’t worry—just mix in some sand or fine gravel to loosen things up. This helps ensure the water can move through easily, which is crucial because no Allium likes “wet feet” (standing water). While you should water them during dry spells, always make sure the soil has a chance to dry out a bit first.
Two Big Exceptions
While the “sunny and dry” rule works for most, there are two major exceptions to keep on your radar:
- Wild Garlic (Ramps)
- Golden Garlic (Allium moly)
Unlike their cousins, these two actually prefer slightly moist soil and spots that range from partial to full shade. In the wild, you’ll often find Wild Garlic tucked away in damp, airy woodlands. This makes them the perfect choice for those trickier, shadier corners of your garden that stay a little more humid.
Pairing with Garden Buddies
Alliums are fantastic team players and pair beautifully with other plants, as long as they share similar tastes in sun and soil. One of my favorite pro tips? Plant them among perennials with lush foliage. Allium leaves tend to turn yellow and wither early in the season, so tucking them behind green, leafy neighbors is the perfect way to hide that “ugly” phase while the flower heads take center stage!
