Most species of Iochroma grow vigorously and require regular pruning. They are easily trained as hedges or topiary shapes. The most common of all species is Iochroma Cyaneum or Blue Cestrum. It grows as a flowering shrub up to 3 meters and produces violet-blue flowers in summer. Flowers grow in clusters and attract bees and garden birds as pollinating agents.

Iochroma Cyaneum requires full to partial sun and regular watering (avoid overwatering). It is propagated from softwood cuttings.
