How much room do you have to play around with? I have seen all types and I remember years ago in school taking a split Forestry/Horticulture class we had to do something similar for a quarterly project.
Someone down the road from us has a small flowerbed with a metal bed headboard and footboard at the opposite ends, I did a DOUBLE TAKE driving by the first time trying to figure out what it was supposed to be....
I have a plot that is 24 x 24 to be developed right now with some more needing to be developed later on by a stream. But right now the 24 x 24 for sure.
What type of flowers do you plan to put in it? That may make a difference in what type of design you want to do. For example, a butterfly garden shaped like a butterfly, a night scented garden shaped like a moon, you get where I am going, right.
Wow, that is a lot to think about. I was just really thinking flowers, no particular type. I think I may need to think about this more. I am gonna looks for some flowers I like and plan from that.
