Bougainvillea
Tropical flowering vines and shrubs with colorful bracts; full sun and good drainage support flowering.
Profile
- Climate
- Protect from frost and freeze
- Size
- Dwarf and vigorous climbing cultivars differ; verify label
- Light
- Full sun
Source: Bougainvillea ↗ — Genus profile supports drainage, drought/heat tolerance, thorns and occasional aphids.
No cited publication establishes a species-wide numeric VWC target. Calibrate sensor thresholds to soil/substrate, rooting depth and field observations; symptoms are not diagnoses. Salt spray tolerance does not establish an irrigation-water or root-zone salinity threshold. Do not extend one form or hybrid’s size/hardiness to the genus.
Water & soil context
- Moisture (VWC)
- Site-calibrated; no universal numeric VWC target established
- Salinity tolerance
- No quantitative root-zone or irrigation-water tolerance established by these sources; test soil and water.
- Drought tolerance
- Drought tolerant when established.
Allow some drying between irrigations; avoid excess water without deliberately causing severe drought.
Source: Bougainvillea ↗ — UF/IFAS: full sun, slightly dry soil, frost protection, dwarf versus climbing forms and multiple causes of poor bloom.
Problems to watch
- Aphids
- Frost injury
- Poor flowering from inadequate sun or excess irrigation
Stress signs
- Poor flowering: assess sunlight, irrigation and pruning; not proof of overwatering
Where you'll find it
- Resorts
- Walls and entries
