Eye-catching is the word. The velvety, funnel-shapedare prominently veined – yellow on red, red on yellow, gold on purple, etc, which makes them one of the most exotic of all . Pinch out the tips of young plants to promote bushiness and support with twigs. Salpiglossis is rather tender – do not grow on an exposed site and a warm summer is necessary for it to show its full glory.
