About the Species 

The beauty. The grace. The history. Hydrangea arborescens is native to North America. Also called "smooth hydrangea" because of their leaves, arborescens are many gardeners' favorite. 

Annabelle hydrangea, an old variety type of hydrangea arborescens that you will still find sold today, dots the landscapes of homes along the eastern United States, particularly New England.

Growing Conditions

They typically enjoy a part-sun to part-shade garden where they will flourish. In the northernmost parts of the United States, they may be able to take full sun, if given the appropriate amount of water. In the south, they are almost certain to burn in the heat and humidity of the hot summer.

Variety Developments

There are many different varieties of hydrangea arborescens and I have several in my own garden. All of the varieties in my garden were developed by Proven Winners. The truth is Proven Winners has poured a ton of research and money into the development of very interesting and unique hydrangea varieties that I've come to really enjoy. Many of the hydrangeas you will find in my garden are Proven Winners varieties for that reason.

Pruning & Maintenance

Hydrangea arborescens more importantly blooms on new wood (the growth from the current growing season), which means they will always bloom for you and you don't have to worry about when to prune.

I personally prune mine by 1/3 in late winter when the buds first begin to swell. Trim out any dead or damaged wood, as well as weak stems to encourage a strong habit that holds blooms upright.
