Hydrangea Types

(Question)

Could you explain the difference between the types of hydrangeas? I am confused as to which is a PeeGee, an Annabelle or a Limelight? Are they all the same variety just different colours? If you can direct me to a site that explains all this, that would be great. Thanks in advance.

With so many new varieties and hybrids in the market, colour is no longer an identifier of Hydrangeas. Let me tried to demystify them a little for you.

The most common types of Hydrangeas available are:

·         Hydrangea arborescens (‘Annabelle’ being one of the most well known ones in this group). The flowers are dome-shaped and the leaves are generally heart-shaped thin, matt and floppy.

·         Hydrangea macrophylla (Bigleaf Hydrangea) – Large colourful mophead or lacecap flowers. This is the group that you see blue (under acidic conditions or pink under alkaline conditions). Leaves are generally heart-shaped, thick, glossy and sturdy.

·         Hydrangea quercifolia (Oakleaf Hydrangea) – Can be easily recognized by the leathery oak-like leaves. Flowers are cone-shaped.

·         Hydrangea paniculata (Peegee Hydrangea) – ‘Limelight’ being one of the varieties. These types of hydrangeas can be identified by their cone-shaped flowers.

Familiarity with each type will help you determine when to best prune it and where to place your plant for best results.

Judith King, a member of the American Hydrangea Society put a website together called: Hydrangeas, Hydrangeas! Which I find it helps with pruning techniques for each type and offers further general information: https://www.hydrangeashydrangeas.com/index.html

Hope you find this information helpful.
