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 9 only describes winter: the coldest night of an average year falls between 20°F and 30°F. This list was composed for the Desert Southwest, with extreme dry heat and very little rain, so plants that fail in those summers were left out even where the zone says they would survive.
A low-water bed uses plants that, once established, get by on rainfall in most years. They still need regular water through their first summer while the roots grow out.
The sample bed is 12 × 6 ft: 5 kinds and 20 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.

Questions and answers
- How many plants do I need for a 12 × 6 ft bed?
- This list uses 20 plants of 5 kinds for a 12 × 6 ft bed (72 sq ft), spaced so they cover about 92% of the bed when mature. Add 6 bags of mulch (2 cu ft) to cover it 3 inches deep.
- When should I plant in zone 9?
- In zone 9, plant in spring from late February to mid-April, or in fall from late October to mid-December. Typical last spring frost is late January to late February and first fall frost late November to mid-December; your own dates can differ by two weeks or more.
- What if I can't find Upright rosemary 'Tuscan Blue'?
- Use Indian hawthorn or Texas sage (Texas ranger): they fill the same role and pass the same rules. Every plant on the list shows two substitutes like this.
- How many plants pass these conditions?
- 47 plants in our table pass the rules for 6 or more hours of direct summer sun in zone 9 and suited to a low-water style. The ones not used in the sample bed are listed above by role.
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.
