Tabernaemontana divaricata 'Flore Pleno'
Light: Bright filtered light or gentle morning sun with afternoon shade; protect from intense summer sun and reflected heat.
Water: Regular water; keep the root zone evenly moist but never waterlogged. Water deeply when the top 1–2 inches of soil begin to dry. Containers may need frequent watering during Phoenix summers; reduce watering in winter.
Soil: Rich, well-drained soil, preferably slightly acidic to neutral. Phoenix’s alkaline soil and irrigation water can cause nutrient deficiencies; containers with quality potting mix offer better control.
Mature size: Typically 6–10 feet tall and 4–8 feet wide in favorable conditions; usually smaller in containers or where cold limits growth.
Bloom: Repeated flushes from late spring through fall in warm, frost-free conditions; flowering slows during cool weather or stress.
Evergreen / deciduous: Evergreen in frost-free conditions; may drop leaves or suffer dieback during Phoenix cold spells.
Growth rate: Moderate to fast with warmth, adequate moisture, and nutrition; slower in containers or stressful desert conditions.
