15-20" tall x 18-20" wide (cutting propagated.) Wonderfully compact, 'Fireball' blooms in mid-summer with compact spikes of bright, scarlet-red flowers. The showy blossoms are held above aromatic, glossy green foliage that is highly resistant to mildew. It's an excellent choice for small gardens or upfront in the perennial border where it will attract lots of hummingbirds and butterflies.
