The cultivar name for Gold Mound spirea was chosen with this bush's main selling point in mind: its golden leaves. Other shrubs may give you better flowers or more striking fall foliage, but this one excels in spring foliage. Learn all about planting and caring for this springtime superstar.
Taxonomy, Botany of Gold Mound Spirea
Description of the Plant
This bush produces pink flowers clustered together in flat-topped flower heads (as on yarrow plants, for example). The shrubs bloom in late spring. These plants attain a height of about 3 feet tall with a slightly greater spread. The habit is mounding.
You grow Gold Mound spirea bush for its leaves, not its flowers. And folks grow it in great numbers, so if you're the type who doesn't wish to plant what your neighbors are growing, it may not be the best selection for you. According to Ohio State University, Goldflame spirea, Crimson Pygmy barberry and this bush "are the three most common deciduous shrubs of small stature in landscapes of the Eastern and Midwestern United States."
Gold Mound spirea's foliage is best at two times of the year, one in spring, the other in fall. In April, you will marvel at the bright golden color of the new leaves. Later, the color changes to chartreuse, which is less exciting. But then the bush makes a comeback with its fall foliage in October, which is a yellow tinged with red.
Planting Zones, Sun and Soil Needs
Uses for Gold Mound Spirea Shrubs in Landscaping
Because of the striking color of their leaves, Gold Mound spirea bushes are more suitable for use as specimen plants than is the cultivar Neon Flash, the latter bearing foliage that's nothing out of the ordinary. Other possible uses include as foundation shrubs and as hedge plants. They are fine plants to attract butterflies.
Care for Gold Mound Spirea
Deadhead Gold Mound spirea bushes after they're done blooming. This will foster some reblooming as the growing season progresses. The easiest way to deadhead in this case is by shearing. In addition to accomplishing the removal of spent flowers, shearing will help you keep the shrub compact and generate new leaves (the newest leaves being the most colorful ones on this plant).
Pruning full branches is usually only necessary to get rid of suckers (if so desired) or to rejuvenate an old bush. You can also prune branches to keep the bush extra-compact if you are landscaping in a small space. If you do decide to prune, you can do so in late winter to early spring without fear of losing your spring flowers, since this plant blooms on new wood.
Not all bushes respond well to the drastic operation of rejuvenation pruning, but spirea is one that does. Prune it in late winter or early spring to rejuvenate an old Gold Mound spirea.
