Tecoma : Greenhouse Plants
W – warm, minimum of 13°C (55°F)
Tecoma stans is the most often grown and makes a large upright shrub which, providing it receives plenty of light, produces funnel-shaped yellow flowers which have given rise to the name Yellow Elder. T. garrocha from Argentina is similar though more graceful and more disposed to climb. Flowers are yellow and scarlet. I think that these are better grown in pots so that they can be placed easily into a position of really good light so that their flowering shoots ripen properly for good summer flowering. After flowering, plants that have become too large can be pruned hard back to within a few buds of older wood. Vigilance against red spider mite is advisable.
