Which of the following plants is noted for its restorative growth characteristics before spring?

Sourwood, known scientifically as Oxydendrum arboreum, exhibits notable restorative growth characteristics before the arrival of spring. This deciduous tree is native to the southeastern United States and is particularly recognized for its ability to generate new growth even in late winter. The plant's unique physiology allows it to develop buds that can burst into growth as temperatures begin to warm, often before other plants start their spring awakening.

This early growth not only supports the tree's vitality but also plays an important role in its overall health and ability to capture sunlight as the growing season begins. Additionally, Sourwood's attractive flowers and autumn colors make it a desirable choice in landscape design, and its early growth cycle supports local ecosystems by providing early nectar sources for pollinators.

Other options listed may have their own merits in landscaping, but they do not share the same notable characteristic of restorative growth prior to spring that Sourwood does. Thus, Sourwood stands out for its remarkable ability to prepare for the growing season ahead of other plants.
