Plant Profile: Cestrum aurantiacum

The Orange Cestrum is a tropical shrub or vine that originates from North and South America. In its natural environment, it can grow up to 15 feet tall; however, in cooler regions where it may freeze back to the ground, its height and width typically reach around 5 feet. The upper part of the plant is resilient to zone 8, while its roots can withstand conditions down to zone 7, making it a suitable choice for many southern gardens. From late spring to early fall, it showcases an abundance of large, tubular orange flowers.

For optimal growth, plant it in full sunlight, although it can thrive with some afternoon shade, provided the soil is average and well-drained. When the plant dies back in the fall, trim the stems and apply mulch to safeguard the crown.

This plant is excellent for espaliers, resistant to deer, and ideal for Xeriscape gardens due to its impressive drought tolerance. Consider placing it at the back of a border or in a nighttime garden adjacent to a patio, allowing you to enjoy the delightful sweet-spicy citrus aroma of its blossoms.

In terms of pests, diseases, and other issues, the Orange Cestrum faces no significant challenges.
