About Hydrangeas

A favorite bloom used in florist bouquets and popular at weddings, special events, and pretty much any occasion, hydrangeas are gorgeous, lush flowers that are as pretty as they are versatile. Notable for their large, showy blooms, the colorful pop-pom-like flowerheads of hydrangeas make them a great cut flower to display in vases. These ornamental blooms have been around for a long time and evoke an old-fashioned charm. With over 70 species and numerous varieties, hydrangeas come in various shapes, sizes, and colors such as blue, pink, red, purple, maroon, green, and white.

Characteristics of Hydrangea

Hydrangeas are most commonly grown as shrubs with big beautiful blooms made up of clusters of smaller flowers called a “corymb.” The most commonly known variety of hydrangea is the “bigleaf hydrangea,” which has the lush, full, round blooms that enchant gardens and florist shops worldwide.

Tips for Creating a Floral Arrangement with Hydrangea

Because of the hydrangea’s large flowerhead, its stems will be top-heavy and can easily flop out of a vase if not positioned correctly. It’s important to choose a container with an opening that’s not too large or to create a grid system with tape to provide structure.

Preparing the Stems

  1. The first step in working with hydrangeas is to cut off all of the leaves below the flowerhead. 
  2. Next, cut the stems at a 45-degree angle with sharp scissors. This allows for the maximum amount of area for the stem to soak up water. 
  3. After cutting the stem, dip the end into a jar of alum, which you can pick up at the grocery store. The alum keeps the cut end of the stem from gunking up and free to absorb water.

Arranging Tips

For a simple yet charming arrangement, put 2 or 3 hydrangea stems in a vase. Cut the stems so the blooms are just above the rim. 

For a more complex arrangement, use an opaque container and the grid method with chicken wire or tape on the opening. Bold blooms such as roses, peonies, and dahlias pair great with hydrangeas. Spire-like flowers like delphinium, freesia, foxglove, and bells of Ireland are perfect for adding vertical elements to the hydrangeas’ low, rounded shape. Experiment with different colors and blooms of different colors, shapes, and sizes. Add some greenery for a more complete look.

How to Keep Your Hydrangea Stems Fresher Longer

  • To help prevent wilting, put a few ice cubes in the water to keep the stems cool. 
  • Give the stems a trim and a change of water every few days to prolong their life. 
  • Dry your hydrangeas – keep them in a few inches of water in a dry, cool place away from sunlight. Once the water has evaporated, usually 2-3 weeks, the petals should feel dry to touch and ready to use in a variety of creative ways.
