Tecoma Stans also known as Yellow Bells, Yellow Elder or trumpet bush belongs to the Bignoniaceae Juss family. They originate in tropical America (West Indies, Mexico). Tecoma Stan comes from desert shrub lands and dry forests in the region from Texas and Arizona southward to Argentina. Yellow elder is a small tree, which grows to 25 ft (7.6 m). It has dense, lushly green foliage that is evergreen in tropical climates, but deciduous in chillier places. The opposite leaves are composite, with three to thirteen leaflets, 2-3 in (5-7.6 cm) long, with toothed edges, and very apparent ribs. They are borne on very short petioles and are slightly hairy on the undersides. The smooth squared twigs are green, turning tan or reddish tan as they age. The bark on the main trunk is light brown and becomes corky with age. The 1-2 in (2.5-5.1 cm) long, sunshine yellow flowers are trumpet shaped. They hang in showy clusters at the branch tips and forks, bending the twigs into arches with their weight. There are two folds along the bottom of the flower's throat and several delicate rust-red lines decorating the interior. The blooms appear in flushes throughout the growing season. They are followed by 4-8 in (10.2-20.3 cm) long string bean-like pods that hang in vertical clusters. These turn brown and split open to release flat oblong 1/4 in (0.6 cm) seeds with transparent 1/4 in (0.6 cm) wings on each end. Hardiness zones: 7-11 (-15øC/ 5øF, 4øC/40øF) in winter. It is reliably hardy, but only down to 28§F (-2.2§C), though the roots may survive temperatures into the low twenties. That tree can take periods of severe drought. They need full sun. Yellow elder will grow on a wide variety of soils, including sand and lime rock, but it likes it well drained. Potted plants should be given minimal water when not in active growth. The Tecoma Stan can also be grown by sea-side.
