To get to the point i will use the information below, with the pertinent reference at the end.
Through history, gardeners hid one from another plants, seeds and information for jealosy, Carl Linnaeus one of the greatests was no exception.
I believe there is nothing to hide, the garden, mine or yours is what it is.
The character of a line yields specific responses. Gentle slow curves and horizontal lines tend to be experienced as restful while jagged diagonals or vertical lines create more excitement and tension.
It is what is seen when first looking at a garden from a distance. Every plant has a distinct growth habit, a unique mass and volume which develops and changes as the plant matures. These shapes whether pyramidal, weeping columnar, spreading or round, divide and define the spaces in the garden.
The siting of a specific plant may block a view, or open a sight-line or alter the view depending on the maturity and growth-habit or the plant open or compact, herbaceous, ever green or deciduous. These plant qualities often change with the seasons and restructure the lines of the garden.
Other elements defining composition, what any garden should be: texture, scent, color, scale, sequence, emphasis, balance, variety and repetition. All the information is in the site provided.
For a farewell I would suggest that you look at the header picture, the first six photos in the right side, moving down to find those between Yucca manihot and Hibiscus.
My garden is in a flat surface, what is not in a fiberglass pot; is in a rectangle surrounded by concrete as you may notice now.
How you deal with your surroundings require constant observation to add and substract. One can not really work with tromp'oleil on a flat surface, as the area I practice, but in one of the pictures down a hill I did.
I would add that assymetry and symmetry are fundamental to master, understand gardening schools or styles.
I am so much into assymetry that even unconsciously, I plant in odd numbers.
It is an acquired taste after my Zen gardening fever passed away.
And it passed away because the only, pragmatic use of the Zen school, in my view, are those spaces enclosed in walls for private enjoyment with white gravel or sand, rocks and perhaps a trio of bushes.
To finish as it is me habit, I do not think that a garden requiring 14 hours of maintenance daily, as many of this gardens with high maintenance require, every leaf clipped, stiff as hell and very orderly are cool to visit, but unless you are wealthy and got hired guns...
