Container gardens add splashes of portable color to outdoor settings, but if you love pots of color, you also know it can take daily attention to keep plants looking their best. One way to expedite the care routine is to fill your containers with shrubs that deliver strong color for the entire growing season. Shrubs typically need less grooming than annuals and do their thing as long as you water. This pair of shrubs features Bangle Dyers greenwood (Genista lydia) and Black Lace elderberry (Sambucus nigra ‘Eva’). Both of these shrubs flower in spring, but the leaves bring strong color and texture all season long.
