Native to the United States, this taller perennial sport of P. Miss Manners with pastel lavender-pink tubular flowers is similarly well-behaved with a non-spreading, clumping habit. Desirable to beneficial pollinators and lovely in cut flower arrangements. Very hardy – worth a try in zone 3.
Why is this called Obedient Plant? When Physostegia flower spikes are in full bloom, you can push the flowers to hold any position you fancy to give them – very helpful when in an arrangement.
