Climbing Hydrangea (Hydrangea Petiolaris)

How do I care for my Climbing Hydrangea?
The Hydrangea Petiolaris is very easy to grow and maintain! This makes it a very popular climbing plant. It does well in shade and in most soil types. It is important that the soil drains well and is not too compact or too heavy. For example, if your garden has clay soil, you can add some lighter soil to it by mixing it into the clay where you want to grow your climbing hydrangea. The Hydrangea Petiolaris is not a fast growing plant, but it can reach heights of four to five metres after several years. It grows in both height as well as width and is easy to maintain in the shape and direction you want. The climbing hydrangea can cope well with pruning. This is best done after flowering or in the winter.

When does the Hydrangea Petiolaris flower?
The climbing hydrangea flowers earlier than the standard hydrangea. Its first flowers appear in May and last until July. The contrast of its large white blooms against its bright dark green leaves is a beautiful sight and attracts bees and butterflies into your garden! The climbing Hydrangea (Hydrangea Anomala Petiolaris) is originally from Japan and Northeast Asia where this climber grows in mountain and forest regions. Because the climbing hydrangea commonly grows there in shade, it is excellently suited to shady locations in your garden.

Does the Hydrangea Petiolaris need to be attached as it climbs?
The climbing hydrangea belongs to the group of self-clinging climbing plants. This means that they climb along a wall or fence with little clinging roots that arise from its branches, just like Hedera (Ivy) and Campsis. You can guide these climbing plants initially, but then they can continue climbing upwards independently. Do not worry about its roots penetrating too deeply into your wall. This is a myth. These climbing plants will help to insulate your home rather than cause damage to it! When you prevent the Hydrangea Petiolaris from climbing, it makes a beautiful shrub or groundcover.
