I love the scent. This very old variety can be hard to find in the US, but in Europe it is farmed for an essential oil used in perfumes. Old House Gardens usually offers it when they have enough stock.

We've had this Iris growing in our gardens for years. It's scent reminds me of a grape lollipop. It's slow to spread.

I love the historic iris, and this is one of the oldest I've found. From the 17th century, this iris is nearly 400 years old!

Collected in 1612, this small iris is one of the earliest recorded in European horticulture.

These iris should not be overlooked. Mine are tall and really pretty, the smell is also neat.
