Flowering Acacia features fuzzy yellow flower clusters with a honey-sweet scent. A sure sign that spring has sprung in California, you may see Acacia trees lining residential streets throughout the state. Having a bright bit of nature inside your home is a great way to ward off the winter blues brought on by the occasional atmospheric river. Give the branch ends a bit of a break, or give them a fresh cut and peel back the bark a bit, to give these unique blooms maximum hydration.
