Carissa macrocarpa 'Boxwood Beauty'
Light: Full sun to partial shade; afternoon shade is beneficial in Phoenix, especially near heat-reflecting walls or pavement.
Water: Low to moderate water once established. Water deeply, allowing the upper several inches of soil to dry between irrigations; water more frequently during establishment and extreme summer heat.
Soil: Well-drained sandy or loamy soil; tolerates alkaline soil but performs poorly in persistently wet or poorly drained locations.
Mature size: Typically 2–3 feet tall and 3–4 feet wide.
Bloom: Occasional flowers from spring through fall in warm weather; this cultivar blooms less abundantly than larger Natal plum varieties.
Evergreen / deciduous: Evergreen; foliage may be damaged by frost.
Growth rate: Slow to moderate.
