The Gold Mound Spirea, scientifically known as Spiraea japonica 'Gold Mound', is a deciduous shrub valued for its vibrant golden foliage and its low-maintenance nature. Here are some key features of the Gold Mound Spirea:

1. Appearance: Gold Mound Spirea is a compact shrub with a rounded growth habit, typically reaching a height of about 2 to 3 feet with a spread of 3-4 feet. It is characterized by its brilliant golden-yellow leaves, which emerge in spring and retain their color throughout the growing season. In late spring to early summer, small clusters of pink flowers bloom, adding a touch of color to the shrub.

2. Hardiness: Gold Mound Spirea is hardy in USDA zones 4-8, making it suitable for a wide range of climates. It is adaptable to various soil types and environmental conditions but prefers well-drained soil.

3. Sunlight: This shrub thrives in full sun to partial shade. While it can tolerate some shade, it will produce the best foliage color in full sun.

4. Landscape Use: The Gold Mound Spirea is prized for its ornamental foliage and its compact size, making it an excellent choice for adding color and texture to mixed borders, foundation plantings, or as a focal point in the landscape. It can also be grown in containers on patios or decks.

5. Maintenance: Gold Mound Spirea is relatively low-maintenance. It benefits from regular watering, especially during hot, dry periods, but is tolerant of occasional drought once established. Pruning can be done in late winter or early spring to maintain shape and remove any dead or damaged wood. It's worth noting that pruning may also encourage more vibrant foliage growth.

Overall, the Gold Mound Spirea is prized for its striking golden foliage, ease of care, and ability to add visual interest to the landscape throughout the growing season.
