Snapdragons are another early, springtime favorite, with tall, sturdy stems that are covered in colorful flowers. They can take cool weather and come in a variety of vibrant solid colors and bicolors, making it even easier to find a solution for every garden project. Plant this pint flower in your favorite container, mixed with other annuals and perennials. Add your finished container garden to your favorite outdoor space for instant color! For healthy plants that will bloom all season, water until plants are established. Then simply water as needed. Feed plants with an all purpose plant food monthly at the base of the plant.
