You would be wise to choose this Perovskia because it's the darkest purple shade to date. Rich lavender-purple flowers are produced on strong, upright plants filled with oval-shaped, notched leaves. This is early to bloom just like its counterpart 'Denim 'n Lace', starting around late July in Michigan. Compared to 'Denim 'n Lace', this is a slightly taller variety with darker purple calyxes and broader leaves, compared to the dissected leaves of the former.
