Use the large specimens only where glazing and floor area genuinely support them. Keep the display accessible behind furniture and avoid repeatedly shifting plants for different photographs. Explain to clients that plant suitability depends on the eventual room, not simply on how it looks in the showroom.

Meaning, with a little thought.
The mix highlights differences in line, texture, scale, and color. The symbolic reading is creative variety rather than a claim that a particular plant defines good design.
