If native plants are altered, do bugs and birds suffer?

The growing popularity of butterfly gardening has spurred sales of native plants at the garden center, and inspired gardeners across the U.S. to add attractive native plants to support insects in our landscapes.

Research into different characteristics of native plants and their links to biodiversity is catching up to the popularity of native plant gardening.
