An oldie but goodie, Seal Lavender is highly fragrant lavender with bright purple flower heads. Like all L x intermedias, it is a perfect choice for a hedge. The strong scent of Seal makes it ideal for potpourri and other fragrant crafts.
Seal Lavender makes a great addition to our Zone 5-11 Fragrant Herb Garden Six Pack.
You might try Abrial Lavender which is similar in growth but a bit darker in flower color.
