What flowers should be planted where in a courtyard? Feng shui has its rules

In a courtyard, what flowers should be planted where? Folk tradition has its rules too.
Proverb 1:
Orchids in front, osmanthus behind, peonies in the courtyard; pine, bamboo and plum at the gate to withstand the cold.
Creeping fig on the spirit wall, golden and silver chrysanthemums before the doors and windows.
Crown of thorns is not a courtyard plant; remove the lilac and keep the golden orchid.
Small peach blossoms open red as fire; enjoyed under the moon at night, their beauty blooms fresh.
Some of these flowers, grasses and trees are arranged according to position, some from aesthetic taste, and some from psychological need. For example, planting willow, Chinese scholartree and jujube before the gate takes their homophones "flow", "embrace" and "early", meaning pearls and agate flow in through the gate, embracing gold and silver treasure, and sons born early.
Proverb 2:Do not plant mulberry in front, do not plant willow behind, do not plant ghost-clapper in the courtyard.
The most taboo is planting mulberry before the gate, poplar in the courtyard, and willow behind the house. The so-called "ghost-clapper" is the poplar, also called "guada shou" among the people. When the wind blows, poplar leaves rustle "hua hua", making people fretful, and it also easily muffles the sound of thieves, so this tree must not be planted in the courtyard.
Mulberry sounds close to "mourning", which folk tradition tabooed; willow is homophonous with "flow", so planting willow behind the house suggests the outflow of money and treasure.
Proverb 3:Chinese scholartree and jujube in front, apricot and elm behind; pomegranate in the east brings gold, persimmon in the west brings silver.
Proverb 4:A willow before the gate, and pearls and agate come walking home. A Chinese scholartree before the gate, and gold and silver treasure come home.
