The Nanho Blue Butterfly Bush is a wonderful shrub for all those hot, drier spots in your garden. The grey-green foliage and large, 8 to 10-inch-long clusters of blue flowers look wonderful in the sun, and those blossoms come continuously from June to the first frost. Not only are they sweetly scented, like honey, they attract many different types of butterflies. Your children or grandchildren will love to watch them come and go, feeding on the nectar. This easy-to-grow plant is only 3 to 5 feet tall, unlike other much bigger old-fashioned kinds of butterfly bushes, so it fits perfectly into smaller gardens or smaller spaces. Plant it below a window, where you can see and smell it from inside. Plant it against lattice or along a picket fence, for that perfect cottage garden look. You will not believe how many flowers it produces, for so little input from you.

  • Beautiful mauve-blue flowers from June to frost
  • Compact size is ideal for smaller gardens
  • Grows well in those hot, dry spots in every garden
  • Attracts beautiful butterflies and excited children
  • Sweet honey scent fills the garden

The Nanho Blue Butterfly Bush will grow in any well-drained soil, in a sunny spot. Once established it is drought-resistant, and it thrives in the heat. It has no significant pests or diseases, and rabbits leave it alone too. The only care is an annual cutting back in spring and removing flower clusters as they fade – it only takes a quick snip, and your plant will reward you with more, and bigger, flower spikes. A little fertilizer in spring will help it grow more vigorously, but this really is a shrub you can plant and forget, even in poor soil, urban conditions, and out in the heat and sun.
