Every Hydrangea variety, A to Z

The Sow catalog tracks 127 distinct Hydrangea varieties, all listed above. The wider genus is larger still — this is what is actually available and documented well enough to grow from, rather than every name ever published.

The genus hub ranks them by how many gardeners actually save and plant each one, which is a better reliability signal. This page is the complete list in alphabetical order instead — useful when you already know the variety name you are looking for.

Some Hydrangea varieties are sold under the same common name by different nurseries, or a cultivar shares a name with the species it came from. Both records are kept and shown with their botanical names so you can tell them apart, rather than one being silently hidden.
