High Invasion Risk - Central, North, South

Tecoma stans: Yellow Elder1

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean 2


This spreading, fast-growing evergreen shrub or small tree can grow to a height of 10 to 30 feet and is noted for its brilliant, bell-shaped, fragrant yellow flowers. Reaching full bloom in fall, yellow elder produces some flowers with each flush of new growth and therefore has some color most of the year.

Use and Management

While sometimes trained to a single trunk, yellow elder is most often used as a specimen or mixed into a shrub border. The somewhat weedy growth requires pruning to control shape, but it is worth the effort due to the brilliant flowers. Its small stature allows it to be used beneath power lines as a street tree.

Growing in full sun on any well-drained soil, yellow elder survives on rain alone making it well-suited to naturalized and low-maintenance gardens. It would also make a nice patio tree and is suited for planting in parking lot islands and medians. The dropping fruit can cause a slight litter problem.

Plants grow easily from seed and can also be propagated from cuttings. Seedlings are easily transplanted and will bloom within two years.


Yellow elder is relatively pest-free with chewing insects and scale being only minor problems.


No diseases are of major concern.
