Perovskia ‘Rocketman’ (Walters Gardens)
From the Walters Gardens, Inc., hybridizing program comes a brand new perovskia named ‘Rocketman’ for its rocket-like, upright habit. Unlike the species, this new cultivar has a distinguished shape that looks neater in pots and landscapes. Aromatic, grey-green foliage is topped with large, fluffy, lavender-blue flowers beginning in midsummer.
