Landscape Attributes
Mellow Yellow Spirea is a multi-stemmed deciduous shrub with a shapely form and gracefully arching branches. It lends an extremely fine and delicate texture to the landscape composition which can make it a great accent feature on this basis alone.
This is a high maintenance shrub that will require regular care and upkeep, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.
Mellow Yellow Spirea is recommended for the following landscape applications;
- Accent
- Mass Planting
- General Garden Use
Planting & Growing
Mellow Yellow Spirea will grow to be about 5 feet tall at maturity, with a spread of 5 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years.
This shrub should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America.
