Why these rules
Full sun means 6 or more hours of direct sun in summer. That opens up the widest choice of flowering plants, but beds in full sun also dry out fastest, so mulch matters.
Zone 6 only describes winter: the coldest night of an average year falls between -10°F and 0°F. This list was composed for the Midwest, with humid summers and cold continental winters, so plants that fail in those summers were left out even where the zone says they would survive.
A modern bed relies on repetition and contrast rather than lots of colour: fewer kinds, planted in bigger drifts, with grasses and clean-edged shrubs doing the work.
The sample bed is 12 × 6 ft: 5 kinds and 29 plants. Taller plants go at the back, grasses and mid-height flowers in the middle and low plants along the front edge, each planted in a group so the bed reads as one planting. Quantities come from each plant's spacing, so a bigger or smaller bed changes the numbers, not the logic.

How this page was made
This page was generated from FloraVista's plant table by fixed rules: the same rules engine that builds paid lists filtered the table for the conditions above, picked plants by role and worked out quantities for the sample bed. No person or chat model chose these plants, and no named expert has reviewed this list.
Data status: the plant table is awaiting review by a horticulturist. Check each plant with a local nursery or extension office before you buy.
