Here I offer a Pint Plant from this spectacular Butterfly Bush Buddleia Black Knight. This is one of the real butterfly magnets. These gorgeous 8 inch flower spikes are just covered with hundreds of these tiny blueish black blossoms, and the butterflies flock to them for all their nectar. The bush will grow to 6 feet and 4 feet wide. The seeds are tiny and just need to be sprinkled on top of the seed starting soil and kept moist to sprout lots of these bushes. USDA Hardiness Zones 6 to 9
