Question
Is there such a plant called a geranium bush? If so where can I purchase them? Thanks for your help

Answer
'Geranium' is used by ordinary people (such as me) to refer, casually, to 2 plants: A hardy perennial flower with the Latin name Geranium OR a tender perennial plant with the Latin name Pelargonium that we often see potted up and placed in window boxes or patios.

However, there is no woody shrub that I have ever seen called a Geranium Bush.

This would not stop someone from using that term.  What are the referring to?  Beats me.

The Pelargoniums that we usually mean when we talk about Geraniums -- with large globes in red, pink, white, or salmon -- can get quite large, compared to other pot plants.  And they live for years.  It would not be unheard of for someone to casually refer to such a large specimen as a Geranium Bush.  I have seen them get to 4 or 5 feet after a few years.  But they don't have the closely spaced leaves and stems that you would expect to see on something called a 'bush'.  Stems in fact can be at least several inches or more often several feet apart.  Even the lushest growth would not get the leaves spaced closely enough to be anything I would consider in the category of Bushes.

I am fascinated by this question.  Please tell me more if you get any more information.  Thanks for writing,
