Incrediball Hydrangea - Is it Invasive?

Posted by brenda_md 6 (My Page) on

I currently have what I believe are three Annabelle hydrangeas. I love their big white blooms. I am redoing some foundation landscaping and was planning on using the Annabelle again, or should I say the new version Incrediball. However, a friend said Annabelles were invasive and suggested I use something else. I have not found my Annabelles to be a problem. Possibly that is because they are in full sun in clay-like soil that is not consistently moist.

Granted, the foundation planting will be better soil. If Annabelle can be invasive, has anyone experienced this with the Incrediball?

Hydrangeas - any - do not fit any of the recognized definitions of 'invasiveness'. Hydrangeas are considered caning shrubs or those that develop new growth/stems - the canes - directly from the root crown and that can over time significantly increase the size of the shrub. So while they can sometimes spread, they are not invasive.

Folks tend to use this term a little too frequently and without a good understanding of just what 'invasive' means. Many different plants will have a habit of growth that results in the expansion of the plant beyond its original planting site.......it does not directly follow that all these plants are therefore invasive. In fact, sometimes this is a very desirable trait.

The term 'invasive' is most properly used to refer to non-native plants that demonstrate an ability to outcompete native plants in natural environments and therefore pose an ecological or economic threat. Annabelle hydrangeas do not meet any of these criteria.

Thanks Gardengal48!!! This is a response that actually makes since. My Annabelles have never been a problem and probably only acted as you said which is adding new canes from the root crown, thus increasing size--and at that very slowly. I feel much better about selecting/using either Annabelle or the improved variety of Incrediball.
