Pump up the volume! ¡®Big Blue¡¯ shows off in breathtaking blooms towering above foliage. First of its kind from seed, it¡¯s a generous host to hummingbirds, bees and butterflies. Vigorous, robust, heat-tolerant, drought-tolerant; needs no deadheading. Struts its stuff in full sun yet tolerates dappled shade or partial sun. Easy to grow from seed, but pinch after the first four leaves to ensure good branching and shape.
