Hydrangea paniculata 'Firelight' is a popular cultivar known for its large, showy flower heads and its ability to bloom reliably in full sun or partial shade. Here's some information about the Firelight hydrangea:

Appearance: Firelight hydrangeas produce large, cone-shaped flower clusters that start out creamy white and gradually transition to a vibrant pink or red color as they mature. The blooms are often multi-toned, with different shades of pink, red, and burgundy appearing on the same flower head. The foliage is typically dark green and provides a lush backdrop for the colorful blooms.

Size: Firelight hydrangeas are typically medium to large shrubs, reaching heights of around 6 to 8 feet (1.8 to 2.4 meters) with a similar spread. However, their size can vary depending on growing conditions and pruning practices.

Growing Conditions: Firelight hydrangeas are adaptable and can tolerate a wide range of growing conditions. They prefer well-draining soil that is consistently moist but not waterlogged. While they can tolerate full sun, they may benefit from some afternoon shade in hotter climates. They are hardy in USDA Hardiness Zones 3-8.

Pruning: Firelight hydrangeas bloom on new wood, so they can be pruned in late winter or early spring without sacrificing flowering. Pruning can help maintain a tidy shape and encourage robust growth and flowering. You can remove spent flower heads to promote continuous blooming throughout the season.

Uses: Firelight hydrangeas are versatile plants that can be used in a variety of ways in the landscape. They make excellent specimen plants, accents in borders or beds, or additions to mixed shrub plantings. Their stunning blooms and attractive foliage also make them popular choices for cut flower arrangements or dried flower crafts.

Overall, Firelight hydrangeas are prized for their stunning flower heads, vibrant colors, and easy care, making them a favorite among gardeners and landscapers alike.
