Seeking fiori di zucca/squash blossoms

Does anyone know if fiori di zucca ever show up at the Soulard or other farmers markets? Does Di Gregorio's or other spots in the Hill ever carry them? Times are tough and one of the ways I'm responding is by making dishes that have changed my life. I know I won't quite be able to recreate the fiori di zucca fritti I had in Rome when I was 20, but I'm definitely down to try. ETA: it's def not the season right now, but just wondering if anyone has seen them at the markets in the spring.
