Tecoma x smithii (Orange Bells) – A large evergreen shrub to 8 to 15 feet tall by at least as wide with orange flowers that have a tubular base and flaring petals. The flowers fade with age to pale orange-yellow and appear from early spring through fall to first frost – can go year-round in frost free years. Best if planted in full sun and watered occasionally but can tolerate light shade where it better tolerates lower irrigation regimes.
