Horticulture Division
Rules & Guidelines

Entrants in the Horticulture Division must complete one horticulture registration card plus an entry card for each container or cut specimen entered. To arrange for a registration card and entry cards in advance, please email, Kate Lowis at KLowis@NewportMansions.org before Friday, June 13, 2025, and indicate the number of entry cards needed.

On entry days, registration and entry cards will be available at the passing tables We encourage you to complete registration and entry cards in advance, if possible. Completed cards should be taken to the Registration tables in the Rosecliff parking lot opposite the passing tables, where horticulture registration cards will be reviewed and marked with an “R” for “registered.”

After registering, please visit the grooming station in the passing area for a final review of your entry before proceeding to the appropriate passing table for your class number. For cut specimens, choose an appropriate vase provided by The Newport Flower Show. At the passing table, your entry will be reviewed, and each entry card will be marked with a “P” for “passed.” And you’re done! Entries will then be staged in The Newport Flower Show.

Please note that entries may not be entered under a commercial or business name. Entries may be made under an estate name.
