10+ Butterfly Bush Leaves Turning Yellow Pictures. But during the growing season, yellow leaves on my butterfly bush can signal other problems. A deciduous shrub, it loses its foliage as a normal part of its growth cycle, and leaves turn yellow in late summer and fall as they die and drop, until the stems are bare when winter arrives.
Buddleia davidii (butterfly bush) is a wonderful shrub with large, fragrant, colorful flowers that attract a flutter of butterflies into your summer garden.
Some plants do turn yellow when they are going into a new stage. I have 3 butterfly bushes and the leaves are turning yellow and wilting in the late afternoon. The majority of caterpillars first roll the foliage with their silk and then feed within. Attract butterflies to your yard with this dazzling butterfly bush!
