Cestrum elegans var. smithii is a native of Mexico featuring pink tubular flowers at the ends of long arching flowering stems to 8'. Grow in full sun, moderate water and fertilization for best results. Like other members of the Solanaceae (Potatoe family), the leaves, stems, flowers and fruit contain poisonous chemicals to fend off predators. White flies are one of the few pests to have developed mechanisms to avoid these toxins. Fortunately, like spider mites, they are prone to diseases in wet/humid environments so a periodic syringing of the foliage with water is often all that is needed to keep pest levels low.
