Plant of the Week: Cestrum fasciculatum
Red Cestrum

Cestrum fasciculatum

Cestrum fasciculatum is an evergreen shrub that will reach 10 feet tall with a 6 foot spread in nature. It is a showy plant that does well in pots or tubs. Red Cestrum is a native of Mexico.

Blooming Time: Summer-Fall. The tubular flowers are about 1 inch long and about 3/8 inch wide. Flowers are formed on new growth in clusters at the tip of branches.

Culture: Cestrum fasciculatum need full sun to partial shade with intermediate temperatures. Winter temperatures should not fall below 50°at night. In the greenhouse, we use a soil mix consisting of 2 parts loam to 1 part peat moss to 1 part sand or perlite. The soil should be kept moist at all times. Fertilize weekly during the spring and summer. In the winter months, fertilize once a month with a balanced fertilizer. Prune all branches back to 4 to 6 buds. This will help in controlling size and create an abundance of flowers.

Propagation: Cestrum fasciculatum is propagated by stem cuttings, layering and by seed. Cuttings are taken in winter and root readily with bottom heat of 70°. Seeds germinate in 14 to 21 days.

Cestrum fasciculatum was featured as Plant of the Week October 27-November 2, 2000.
