Sedum ‘Autumn Joy’ -- Another great choice for late summer flowers and winter texture. Its flowers bloom from August into November; they open pink and mature to a copper befitting of autumn. It is 2 feet tall and wide, with succulent stems and leaves.
Dwarf variety of Purple Fountain Grass (Pennisetum setaceum ‘Rubrum’). Here planted with annuals, but in zones (where this grass is perennial), would be very nice w/ orange Lantana. (plant info on other pins)
