The Hydrangea, a gorgeous flower with big, bountiful blooms, can improve the curb appeal of any home. It’s a bona fide flower garden showstopper!

It can, however, be finicky to grow. It blooms on either “new wood” or “old wood”. New wood refers to the stems that have just developed on the plants during the current growing season. Old wood refers to the stems that have been on the plant since the summer before the season in which they are currently blooming.

Always remember that spring and fall are the most ideal planting seasons. However, if the flowers are container-grown, you can plant them at any time because their roots are raring to go.

Popular Types of Hydrangeas

Hydrangea Macrophyllia

  • Hydrangea Macrophyllia can grow to be very large and round-shaped.
  • They rarely need to be pruned — the only exception is when there is dead wood on the plant. A mistake most people make is that they prune them too soon. What you may not know is that your plant is already in the works of creating buds for next season. If you prune them too soon, nothing will grow the following season.
  • It is also important to note that in most parts of the country, with the exception of the far east and west, the plant will only produce foliage.


  • For the northern climates, the Annabelle is best.
  • These beauties bloom on new wood in a soft ivory shade. This means that even if you prune them to the ground, they will regrow for next season.
  • Sounds too good to be true, right? Well, you are right. There’s only one issue: their heads can become so large that they will start to bend down from the weight. This can be avoided by tying them stems together, or making sure the stems are nice and durable when you are buying them.


  • The Paniculata comes in a cone-shaped bloom that grows on new wood.
  • This is by far the easiest one to maintain and a favourite among home owners for its simplicity.
  • It will grow to be quite high and is usually used as the centerpiece of a garden for its beauty.


  • Limelights come in a stunning chartreuse green and bloom on new wood.
  • These are a bit shorter than the others, usually growing as high as 3 ft in height. These guys are low enough to the ground that when winter hits, the snow can rest nicely on top without bending the stems.
  • The Limelights can also be substituted as a border or even a hedge.

  • I have grown one for 15 years and love the variety of colour just one plant can produce. I understand it has to do with the acidity/ alkaline differences in my soil…
