Hydrangea paniculata 'Tardiva'

Also Known As - P.G. Hydrangea
The panicle hydrangea, Hydrangea paniculata 'Tardiva', is a hardy deciduous shrub that is native to eastern Asia. This showy plant features lacy flower clusters that bloom white in summer, gradually deepening to a pinkish hue. These large clusters can grow up to 3 feet wide and can persist into winter. Its green foliage turns to beautiful shades of yellow, orange and red in fall. This deciduous shrub prefers full sun and can tolerate part shade. New growth sustains repeat blooms throughout the season. With some pruning, it can make an attractive screening plant around homes and gardens.

watering

For panicle hydrangea, water when needed and water deeply. Generally, the plant should receive 1 to 1.5 inches of water each week. This can be achieved through either natural rainfall or supplemental watering. During periods of drought, increase watering to ensure the soil remains moist. Allow the soil to dry slightly between waterings to prevent root rot. When supplemental water is needed, water the soil directly, making sure to avoid getting water on the foliage.

sunlight

Panicle hydrangeas, which belong to the botanical family Hydrangeaceae, thrive in full sun or partial shade. They require at least 5 to 6 hours of direct sunlight a day, particularly in the late morning and early afternoon. For best results, plant panicle hydrangeas in a spot where they will receive at least 1 hour of direct morning sunlight and several hours of bright, indirect light during the rest of the day. Despite their sun needs, it's important to not overdo it, as panicles need some protection from the intense heat of the late afternoon sun.

pruning

Panicle hydrangeas should be pruned once a year in early spring just before new growth begins. In late winter or very early spring, remove any dead, damaged, or crossing branches and cut back 1 to 2 year old wood by 1 third to 1 half of their length. Panicle hydrangeas can also be shaped by selective pruning, cutting out individual stems at the desired height.
