When you're planning a colorful garden, petals aren't the only thing to consider. Leaves, too, vary in hue, impacting the garden's overall style. Silver leaves (such as dusty miller) mesh well with soft pink, blue, and lavender blooms, for an English-country look. Deep-brown foliage (such as black lace elderberry) provides a great foil for creamy yellow and pale blue. And chartreuse leaves (such as variegated euonymus or variegated boxwood) look modern paired with bright orange and yellow buds.
