P. tanacetifolia is sometimes cultivated as an ornamental and has also been introduced for trial as a nectar source because the fls are reported to be very attractive to bees. The much larger-flowered P. campanularia Gray is sometimes cultivated as an ornamental annual; the lvs are simple and the sky blue corollas are c. 1.5 cm diam.
