Color in the home landscape during the summer months is usually supplied by perennials and annuals. However, gardeners can add color to the green landscape by planting yellow- or gold-leaved shrubs. The yellow- or gold-leaved shrubs are excellent accent or specimen plants, but should be planted in moderation. Large numbers of yellow- or gold-leaved shrubs in the landscape become distracting.

Golden Privet (Ligustrum x vicaryi) is a vase-shaped shrub that commonly grows 4 to 6 feet tall, but can reach a height of 10 to 12 feet.

Goldflame Spirea (Spiraea x bumalda 'Goldflame') is a small 2 to 3 foot shrub.
