Burning bush ablaze with colour

The colourful foliage this time of year is hard to beat, one of the reasons fall is the favourite season for many.  The burning bush in my neighbour’s garden is absolutely gorgeous this year.

Temperature, moisture levels and the amount of sunlight dictate just how colourful the foliage becomes.  Apparently the vivid colours on the deciduous trees and my neighbour’s burning bush can be attributed to the wet growing season we had as well as the cool nights and warm days this fall.  The scientific explanation involves fancy words like:

  • xanthophyll (yellow pigment)
  • carotenoids (orange pigment)
  • anthocyanins (red and purple pigment formed by sugar trapped in the leaves)
  • chlorophyll (green colour)
  • abscission layer (when nights get cooler, this layer forms blocking chlorophyll from entering the leaves, so other colours are visible)

Also (still) looking good are some of the containers I planted this season.  We have had a few frosty nights, but nothing severe enough to slow these beauties down:

As long as this nice weather continues I just may get all my gardens put to bed this week!
