Summary
Iochroma cyaneum, commonly known as Blue Cestrum, is an evergreen shrub native to the cloud forests of the Andes in South America. This species typically grows to a height of 10-13 feet (3-4 meters) and a width of 5-6 feet (1.5-2 meters). It has a bushy habit with elongated leaves and tubular flowers that are most often blue or purple, attracting hummingbirds and other pollinators. The flowering season extends from spring to fall, with the blooms being quite showy and abundant.
Blue Cestrum is valued for its long flowering season and vibrant flower color, which can add a tropical feel to temperate gardens. It is often used in mixed borders, as a specimen plant, or for creating a privacy screen. In cultivation, it requires protection from strong winds and prefers a sheltered position. While it tolerates a range of soil types, it thrives in well-drained, fertile soil and benefits from regular watering, especially during dry periods. It can be grown in full sun to part shade, with part shade being preferable in hotter climates to prevent leaf scorch. Pruning can be done after flowering to maintain shape and promote bushier growth. Be aware that all parts of the plant are toxic if ingested, and it can be susceptible to pests like aphids and whiteflies.CC BY-SA 4.0
