“Bluebird” is an additional remarkable lace-cap hydrangea. This shrub is distinctive in that it has a two-toned appearance because of the enormous clump of deeper blue fertile flowers surrounded by light blue florets.

This is a very lovely choice for a blue-flowering shrub. It loves a little shade. It has an abundance of flowers during the early summer. “Nikko Blue,” when it reaches six feet in height, will offer sufficient seclusion to be used as a screen or planted next to a wall or fence. Pruning should be done carefully because it blooms on aged wood.

Old wood bloomers don’t usually require much pruning, but if you do need to remove any growth to keep the plant in its desired form or size, it’s best to do it in August or September, soon after the summer blooms. If you prune your hydrangea after September, it will not bloom the next year.

3. General Vicomtesse DeVibraye

This is a personal favourite of mine. The blossoms on “Mathilda” have a deep, almost purple-blue colour and occasionally a lighter blue center that gives them the impression of being tie-dyed. Early summer to early autumn is bloom time.

Bigleaf hydrangea, or Hydrangea macrophylla, and partially H. serrata will respond to the pH and aluminum content of your soil. By enabling the hydrangea to absorb more aluminum, more acidic soils—pH levels below 5.5—will promote blue blossoms.
