This is Allium, a flowering plant that has more than 500 species. The most common flower variety in this part of the country is the deep purple globe. Her globes range from two to 4”inches in diameter, and she can stand as high as 4’. I also have a small white Allium which has not yet bloomed. Since this is the white’s first season, I don’t expect her to get more than a 1’ tall with globes no more than 1 -2” in diameter.
Many of her species have been harvested for eating. Today the most common are French Shallots, Leeks, Scallions, Garlic and Chives. I would not advise eating the ornamental Allium.
Some Allium can be found in Africa and South America; however they are primarily indigenous to the Asian Northern Hemisphere. Their habitats range from mineral soils that are dry and well drained to moist organic soils. Some even grow in swamps and forests. Mine like heat, dry mineral soil, sun and a lot of drainage.
They are usually grown from bulbs and fill in nicely for a back border or garden divider. Butterflies like them and as you can see, so do bees.
