Look at the positions that wildflowers take in nature. They are as a rule in protected places when they occur in massive quantities: places away from traffic - often on grassy banks, on corners of fields, against a wall. It is not natural for flowers to grow in bundles like flower beds; they need a place to nestle.
What are the issues?
1. The sun - they need plenty of sun.
2. A position where people can smell and touch them.
3. Protection from stray animals.
4. A position where people see them, either from inside a house or along the paths which they naturally pass coming and going.
Typical flower borders are often too deep and too exposed. And they are so low the flowers are out of reach. Concrete planter boxes made to protect flowers often go to the other extreme. They are so protected that people have no contact with them ' except from a distance. This is next to useless. The flowers need to be close, where you can touch them, smell them.
Therefore, instead of putting the flowers in low borders, on the ground, where people walk, or in massive concrete tubs, build them up in low beds, with sitting walls beside them, along the sides of paths, around entrances and edges. Make quite certain that the flowers are placed in positions where people really can enjoy them - and not simply as ornament: outside favorite windows, along traveled paths, near entrances and round doorways, by outdoor seats.
