Choose compact specimens and one narrow floor accent. Avoid buying a mature plant solely because a smaller pot temporarily fits a shelf. Keep watering access straightforward, and make the best lit position a shared growing station rather than hiding plants among ornaments.

Meaning, with a little thought.
The selection suggests that a small space can still hold detail and care. A few healthy, appropriately placed pots are more coherent than an overcrowded collection.
