A Tampa-based orchid grower has filed a federal civil rights lawsuit against the Florida Department of Health and several current and former state officials, alleging constitutional due-process violations related to the nursery’s attempt to get a medical marijuana license.

The lawsuit, filed last week in Tallahassee by prominent Jacksonville civil rights lawyers William Sheppard and Elizabeth White, is the latest effort by Louis Del Favero Orchids Inc. to enter the highly restricted medical marijuana market in Florida, where operators have sold licenses for upward of $50 million.
