I absolutely love these flowers. They are Allium which derives from the Latin word for garlic! They are actually in the onion, chive, garlic family and the flowers resemble the smaller purple flowers that appear in chives. The flowers don’t smell like onions or garlic, though.
From Wikipedia: Allium is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name Allium is the Latin word for garlic, and the type species for the genus is Allium sativum which means “cultivated garlic”.
I bought a bag of Allium bulbs at Aldi last year and stuck them in the ground around Florence. This year, much to my surprise, I was surrounded by beautiful allium blooms that I just couldn’t help but to pick some.
