The neighborhood pollinators will be all in a buzz if you plant yellow giant hyssop in your garden. Widely spaced palest yellow flowers open for many weeks on tall upright bold-leaves stems, drawing in lots of friends. The candelabra seedheads that follow evolve from green to dark gray in late summer and fall, providing an architectural late-season garden feature. This central and eastern U.S. native is a highly underrated ornamental. 3.5-inch pots. Zone 4.
Part shade to sun; moist humus-rich soil; 5'x2'; summer to fall
