The ornamental onion is a type of flowering plant that belongs to the Allium genus. It’s native to parts of Asia, Europe, and the Middle East, but it’s now grown all over the world.
It’s a perennial, which means it comes back year after year. It likes well-draining soil and sunlight, and it’s hardy in zones 4-9. It has round clusters of small flowers that are shades of pink and purple. The flowers are on tall stems and are surrounded by long, narrow leaves.
It usually grows to about 1-3 feet tall and spreads out about 1-2 feet wide. It can handle a variety of climates, but it’s not frost-tolerant, but will come back each year.
Ornamental onion plants are not only attractive, but they are also deer-resistant and drought-tolerant, making them a good choice for gardens in areas with these challenges.
