Landscaping Concept Clarification
In my efforts to educate myself on landscaping, I recently picked up a book called Gardening and Landscaping in Central Florida. It's a pretty good book and it has helped me with fixing some things in my yard that I had done a little wrong. But at one point it mentioned the concept of Odd Groups, keeping plants in groups of 1, 3, 5, etc. Unfortunately, it did not explain why this concept was used and I ended up looking that up myself and I understand that is has to do with how people are apparently naturally inclined to notice odd numbers instead of even.
But what I'm curious about, does the Odd Groups concept mean that it has to be an odd number of the same plant? Or will an odd grouping of mixed plants work as well?
Quick example. Is it better to have 3 dwarf hollies, an ornamental tree and then 3 dwarf hollies (7 total) or would 2 dwarf hollies, an ornamental and 2 dwarf hollies (5 total) have the same effect? Or... would the even number of dwarf hollies on each side of the ornamental make the ornamental stand out more as the eye would be subconsciously drawn to it more?
