‘Runaway Bride’ is the brainchild of Ushio Sakazaki, the veteran Japanese ornamental plant breeder who changed the plant world years ago with the introduction of the ‘SURFINIA’™ petunia. He also selected the very first ‘mini petunias’, the magic bells (Calibrachoa), which were named Petunia ‘Million Bells’ by the Royal Horticultural Society.

After Ushio Sakazaki revolutionized petunias, he set to work on the popular hydrangeas . He looked around for species with more flowers. He carefully studied their growth habit and branching before selecting an Asian species to cross with the commonly known Hydrangea macrophylla. What he created was an entirely new class of hydrangea – the festoon hydrangea!

Most hydrangeas (Hydrangea macrophylla) bear their flowers in imposing inflorescences. What makes the Garland Hydrangea ‘Runaway Bride’ special is that it also blooms from the side shoots of the branches, creating entire garlands of flowers along the graceful shoots, up to 20 flower heads per stem! This new breakthrough variety has the bloom we’ve always dreamed of!

Fertilize every 14 days with a hydrangea fertilizer. Place a saucer under your plant to serve as a water reservoir.

The festoon hydrangea is hardy in Germany. Frost can cause great damage to young buds and reduce the number of flowers, so it is advisable to protect the plant with fleece.

If you want to keep the hydrangea in a pot, you should choose a pot with a diameter of about 40 cm and a depth of 30 cm. This is planted with a plant. To prevent the soil from drying out too quickly, do not use terracotta tubs. A vintage-style planter will harmonize wonderfully with the romantic flowers of the hydrangea, but it can also look good in modern tubs in white, anthracite or black.

It should be ensured that the plants absorb enough water and nutrients and receive sufficient light.

Cut garlands hydrangea

Correct cutting of garlands hydrangea

Hydrangea ‘Runaway Bride’ blooms on previous year’s wood, so be careful when pruning.

During the summer, remove old blooms periodically to stimulate flower formation. In the fall after flowering, new shoots will develop and bear the next year’s flowers. Leave the faded hydrangea flower heads until spring to protect the tender new shoots from frost damage – they look beautiful when covered with frost, and of course they provide shelter for overwintering wildlife.

Garlands hydrangea cutting

The ideal time for major pruning is February through March (before bud break). Cut back faded shoots to a strong pair of buds. Remove damaged, dead as well as misaligned branches. Once the plant is established, remove a quarter to a third of the shoots at the base each year to encourage the production of new shoots that will bear more flowers.

Note: Plant parts are mildly toxic and may cause mild stomach upset if eaten. Contact with leaves may aggravate skin allergies. Gloves and other protective equipment should be worn when handling.
