6 Sterile Butterfly Bush Varieties From Proven Winners

The signature fragrant flower panicles, woody stems, and coarse-textured green foliage have made butterfly bush a staple for home and commercial landscapers. When paired with other host plants and native perennials, this vibrant shrub can play a vital role in the pollinator garden. Luckily, for gardeners who love butterfly bush blooms but are concerned about their ability to spread, Proven Winners ColorChoice Shrubs has just announced the InCheck plant program, which features sterile varieties of invasive species, some even approved for sale in Washington and Oregon! Here, we list the Proven Winners ColorChoice Shrubs butterfly bush (Buddleia) varieties that are sterile and InCheck.

The InCheck program was created by Proven Winners ColorChoice Shrubs and includes a collection of ornamental shrubs that were cultivated to be nearly seedless, reducing the risk of spreading in the garden. This designation is used only for shrub species known to be invasive in certain areas, such as butterfly bush. Now, gardeners can confidently add these sterile plants to their landscape without the risk of spreading, enabling better plant management and control.

Lo & Behold 'Purple Haze' butterfly bush isn't even your average member of the award-winning Lo & Behold series: it's still dwarf, non-invasive, and blooms all summer without deadheading, but it has a strong horizontal, wider-than-tall habit and large, pendulous flower spikes that cascade downward. It's a very unique - and very showy - look that brings a new level of appeal to the garden.
