Landscape Attributes

Invincibelle Sublime™ Smooth Hydrangea is a multi-stemmed deciduous shrub with a more or less rounded form. Its strikingly bold and coarse texture can be very effective in a balanced landscape composition.

This shrub will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting bees and butterflies to your yard. It has no significant negative characteristics.

Invincibelle Sublime™ Smooth Hydrangea is recommended for the following landscape applications;

• Accent
• Mass Planting
• General Garden Use
• Naturalizing And Woodland Gardens
• Container Planting

Planting & Growing

Invincibelle Sublime™ Smooth Hydrangea will grow to be about 5 feet tall at maturity, with a spread of 5 feet. It tends to be a little leggy, with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub performs well in both full sun and full shade. However, you may want to keep it away from hot, dry locations that receive direct afternoon sun or which get reflected sunlight, such as against the south side of a white wall. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. To help this plant achive its best flowering performance, periodically apply a flower-boosting fertilizer from early spring through into the active growing season. 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. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selection of a native North American species.

Invincibelle Sublime™ Smooth Hydrangea makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception.
