Use one plant per pot
Kissinger set one plant into each white ceramic ‘Cylinder’ container, from Gainey Ceramics (gaineyceramics.com).
Why it works: A single plant with a bold, sculptural shape is easier on the eye than a mixed planting. And a white pot allows it to shine.
Adapt the idea: You don’t have to buy large, expensive specimens like Kissinger did―try smaller agaves or ferns instead.
