10 Rapid-Growing Annuals to Brighten Your Garden in a Flash## Arugula
Arugula (Eruca sativa) is an incredible addition to salads, dishes, and your garden alike. Jabbour loves it for its peppery kick and quick growth.

Sweet Alyssum (Lobularia maritima) offers a fragrant aroma and fast growth, making it the perfect low-growing flower to complement your garden with its pink, white, and purple blooms.
