Kaktus said: @bumplbea , Do you need to re-plant most of your flowers every year ? 4 to 6 years ago ( don't remember when), I visited The Butchart Garden in Canada, a lot of beautiful flowers, I asked them whether they planted the flowers once, and every spring/summer the flowers are just wake up from dormancy and started to bloom ? The people in there said "No, we have to re-do almost everything every year" . .. .. If I have to re-plant everything every year, I think I'll quit gardening 
Hi … Kaktus, What a good question. I don't need to plant flowering plants yearly, and here's why.
All the plants in my garden that are flowering bulbs, perennial's, trees and shrubs like rhododendrons, azaleas , magnolias are for spring blooming and many other flowering plants will flower at different times during the growing season .
The vines, trees and perennials are well established . Many plants flower at different times during the growing season from spring thru to the end of fall. And never forget foliage for texture , size and color, the variegated and big leaf to small leaf patterns that all have their place in my garden. Together they all make up a 'Four Season' garden even in winters. Winter, spring , summer and fall the beauty of living in a 4 season gardening zone and plants that bloom during each season.
I rarely purchase plants. I usually grow annuals from cuttings and add in areas of full sun exposure to fill in blank spots and fill in pots. Most small shrubs like hebe's ,azalea's are all grown from cuttings and many trees were grown from cuttings or seed. It seems the only work to do during spring and summer is management of weeds and of course during winter a lot of editing .
The Bouchart Gardens are fantastic with a huge crew , we are in same growing zone and grow a lot of the same trees, shrubs and perennials. I am the crew….
, so my garden is designed with as less maintenance as possible. I think I'm loosing that battle..
The only plants Bouchart's were referring to for replanting on a 'Yearly Basis' are the many annuals that are used profusely in their gardens to allow that visual sea of waves of colorful blooms thru summer to fall. Plus they always plant tulips for early spring blooming and other blooming bulbs that are all planted to bloom in succession yearly .
Every plant that flowers has it's own particular time of flowering in each of the four seasons. The timing of the plants that bloom in succession thruout the growing season in our zone are the choice of plants used to achieve blooms thruout the season.
I hope that answers your question on the planting cycle for a Four Season Garden.

Absolutely gorgeous! My garden is only a 1/4 acre and mine is not even close to the way your garden is laid out and organized Bea! And it doesn't help that depending on the time of the year or my hubby's mood he keeps thinking of selling our home and transferring to an age-restricted community or a bigger yard away from the "busy" area. So all my favorite plants are in pots just in case we have to move!
