Plant for the weeks after the first colour.
Begin with the region
Climate, soil, light, moisture, native range, invasive risk, local advice, and seed provenance come before a plant list.
Overlap the bloom
Early, middle, late, and winter structure are planned with variation because weather and plant performance are uncertain.
Protect more than flowers
Nesting, bare ground, stems, leaves, water, mowing, pesticide exposure, pets, and neighbours remain part of the garden.
