All About Panicle Hydrangeas

These hydrangeas are so easy to grow and their blooms are stunning – both in size and in color. Proven Winners even calls them the “black thumb hydrangea” because of their ease of growing. The blooms are larger than other hydrangeas and shaped like a football. They all start out pure white and change to pink and reds as fall approaches.  


They bloom later in the summer on new wood – meaning they leaf out in the spring and then set their flower buds. This means you can prune the plant in the fall or in early spring without negatively affecting the blooms. (Goof Proof!)

Notes:

  • They like morning sun and afternoon shade – too much shade will result in fewer blooms.
  • Don’t amend the soil – plant them directly into your soil – super simple!  
  • They grow in different soils (even clay) if the soil is well-drained. Soils that are too wet lead to root rot, so make sure the soil does not stay wet for any length of time.
  • Their color cannot be changed to blue by adjusting the pH level of your soil – the blooms start out white and will naturally change to pink or red as the bloom matures.
  • You can prune in fall or spring. Prune off about 1/3 of the plant. You may find it easier to prune in the spring after new growth appears. Cut the stem above where healthy buds are emerging, this is usually about ½ or 1/3rd down the stem.  
  • The blooms make excellent cut flowers but the color they are when you cut them is the color they will keep. They will not change from white to pink/red after cutting, so if you want pink/red wait until they are pink/red to cut them.

Watering is important. If you see your plant wilt it can be caused by too much water or not enough water. 


Here’s how you can tell the difference:

  • Overwatered hydrangeas drooping foliage feels soft and limp and the flowers often wilt. 
  • Underwatered hydrangeas drooping leaves feel dry and crispy, can have light brown spots around the leaf edges or look dusty in color. Unless they are exceptionally under-watered the flowers usually won’t be wilted.

If you have a spot in your yard that gets morning sun and afternoon shade, plant one of these lovely ladies. Their showy blooms, flower color transition and ease of care makes this a much sought after plant.
