Endless Summer Hydrangeas Bloom Longer Than Ordinary Hydrangeas


New Hydrangea varieties bloom in early summer and keep blooming through the fall.  Older varieties only develop flowers on last year’s growth.  New varieties develop flowers on both old and new growth.  As a result, these new varieties of Hydrangea bloom longer and produce more flowers.[639]  Here are some newer Hydrangea varieties that bloom for a long time and are easy to grow.

  • Hydrangeas grow best in part-shade in rich, moist soil.  Six hours of sun or dappled sunlight all day is ideal. Prune to control the plant’s shape and height.[639]  
  • Trim off old flowers to encourage more blooms or leave old blooms for winter interest.  
  • You can cut the flowers and use them in flower arrangements for inside the house.[639]
  • Use hydrangeas in shrub borders, mixed plantings, or plant around the house as a foundation plant.  Hydrangeas can even be grown in large containers.
