Which plant is described as a fast-growing, deciduous flowering shrub with arching branches and small white flowers in spring?

• A. Butterfly bush (Buddleja)
• B. Red Fescue
• C. Meyer Zoysia
• D. Vanhoutte's spirea

Answer: (A)

Recognizing a bridal-wreath type shrub is the key idea here: a fast-growing, deciduous shrub with arching branches that bursts into small white blossoms in spring. That description fits Vanhoutte’s spirea (Spiraea x vanhouttei) perfectly. It forms a graceful, arching habit and puts out abundant tiny white flowers along the stems in spring, often before the leaves appear, creating a bright, cascading effect. Butterfly bush tends to have longer, showier flower clusters in summer and isn’t the same small white spring bloom phenomenon. The other two options are grasses and not flowering shrubs, so they don’t match the described plant.
