This deciduous shrub is known for its bright yellow flowers that bloom in the spring, making it a popular choice for gardeners and landscapers looking to add a pop of color to their outdoor spaces.

In terms of care and maintenance, Yellow Azalea is relatively easy to grow. It prefers well-drained soil and partial to full sun, although it can also tolerate some shade.
