Lo & Behold®  'Purple Haze' is a different duck than all the other Lo & Behold Buddleia. Developed by Denny Werner of NCSU, this hybrid selection is a low, wide-spreading variety that makes it a great selection for use as a ground cover or in a decorative container. Like all of the Lo & Behold® series, we had to test it for sterility. This is a sterile variety that does not produce unwanted seedlings. It passed the test and can now be sold in Oregon where other Buddleia are banned. 

A low spreading charmer of a butterfly bush, Lo & Behold 'Purple Haze'  has uniquely horizontal branches that produce an abundance of fragrant dark purple-blue flowers. The flowers radiate outward and downward like a pinwheel, and are continuous from mid summer to frost. It makes a great mass planting or foundation planting, or can be incorporated into perennial gardens and mixed borders.

Cold, wet winters can be really hard on buddleia, so here are a few tips to help your buddleia thrive in your garden:

1. Make sure the soil is well-drained. That place where the plow truck dumps snow in the winter? Not a good idea.

2. Full sun. That's at least 6 hours. No cheating.

3. Plant early in the season. This gives the plants all summer and fall to establish. Fall planting can be chancy in northern regions.

4. Wait until it leafs out in spring before pruning. In some years you may have to prune it back to the ground. After milder winters, maybe not so much. Avoid fall pruning.

Fun Facts: 

This non-invasive variety is approved for sale in Oregon and Washington, though it will be called a "summer lilac" instead of a "butterfly bush."

  • Planted 5 (2 two years ago, 3 more last year), and only 2 came back this spring. They are quite attractive while blooming, and bloom for a long period, attracting many butterflies. But apparently not reliable.

  • This shrub was perfect in the border garden. It kept producing flowers without deadheading and they bloomed a long time.
