Flowering Alliums Transform Your Yard for Weeks

Alliums are beautiful bulb flowers that are actually ornamental onions, and the blooms are absolutely gorgeous. The bloom typically consists of a perfect sphere of hundreds of tiny flowers, and each is elegantly perched atop a single sturdy stem.

No other flower compares to this breathtaking display of color. This species is definitely a unique bulb flower that brings drama and color to a yard or garden.

If you’ve had problems with deer eating plants in your yard or garden, these bulbs are a great choice. Deer aren’t at all tempted by this plant species, and they will pass up them up without taking so much as a nibble.

Consider planting alliums if you want bulb flowers that will turn heads and capture hearts. They are beautiful flowers that, unlike many other perennials, will last for weeks at a time.

These flowering plants are sure to make your yard or garden an impressive area you’ll be proud to display. The following cultivars are some of the most beautiful in the allium family.

Beware, some of these alliums can become real pests in sandy soils. After they’ve been down for a while, the bulbs divide and get smaller, until they are too small to bloom, but still make foliage like turf.

Hello Robert – Thank you for raising a very good point. Many alliums are vigorous self-sowers that form a thick mat of roots and tiny bulbs that remains long after the flowers have dwindled. When selecting plants, it’s good to check with the local agricultural extension to avoid varieties that are likely to be invasive in a particular region. Deadhead plants that drop seed and choose cultivars that are infertile to minimize self-sowing.

Now wild garlic is a different story, burn that one in a hot fire.

Hi Kathy! Thank you for your question and for providing photos. That’s definitely an allium flower, and it does look like it needs more sun. While some alliums can tolerate part shade, one of the main reasons the flowers flop over like that is lack of sunlight. This is because the stems strain toward the light and get extra leggy too quickly, resulting in a weaker stem that can’t hold up the flower. (I’ve had this happen while using grow lights indoors with several types of seedlings!) The good news is that you can move this allium into the sunshine… Read more »
