Which plant listed is known to grow before spring and is typically associated with flowering shrubs?

The Goldenrain tree is recognized for its early flowering capabilities and is often associated with flowering shrubs. This tree typically produces bright yellow flowers in late spring, which can herald the arrival of warmer weather. Its blooms can provide aesthetic value to landscapes, creating vibrant color before many other plants have started to leaf out.

In contrast, while the red maple is an early bloomer in terms of tree species, it is primarily notable for its red flowers that emerge in early spring rather than being categorized as a flowering shrub. Birch trees also focus more on their beautiful bark and are not distinguished for early flowering. Sweetgum trees are appreciated for their star-shaped leaves and unique fruit but do not have a prominent association with early flowering or the characteristics tied to flowering shrubs. Therefore, the Goldenrain tree stands out as the correct choice due to its notable early blooming characteristics and association with flowering traits.
