Designing a Perennial Border with Descending Heights

Creating Visual Flow in a Small Bed

For a sunny, clay-soil bed near an AC unit in Zone 9 (Stockton, CA), select perennials that tier from tall (back) to short (front) for a cohesive look.

Soil Improvement

Amend clay with compost, coarse sand, and perlite to improve drainage. Raised beds or mounding help. Mulch with gravel or crushed rock for heat-loving plants.
