I have been searching for 'Marconi' shasta daisies. None of the
nurseries in the San Fernando Valley of Los Angeles or in Ventura County
seem to carry them.

I did a Google search on "marconi 'shasta dais'" CA OR Calif OR
California". I got many results, but none of them offer 'Marconi' for
sale.

Are these no longer being grown commercially?
