PHS releases new Gold Medal Plants winners list

The list has been shared and now it’s time to see what varieties have been selected by the Pennsylvania Horticultural Society (PHS) for the 2024 Gold Medal Plants winners.

The Gold Medal Plant Program was created by PHS in 1979 to celebrate and showcase beautiful, easy-to-grow plant species that are ideal for home gardening.

Each year, a committee of horticulture experts convenes to assess trees, shrubs and perennials on various criteria including their suitability for home gardens in the mid-Atlantic region, ease of cultivation, ready commercial availability, wildlife value, weather tolerance and pest resistance.

Since the program’s inception, PHS has named over 150 Gold Medal Plants. Including this year’s winners, all plants are indicated for their hardiness in zones 4 to 8 on the USDA’s hardiness zone map, making them ideal choices for the Mid-Atlantic region.

“The PHS Gold Medal Plant program provides amateur and professional gardeners alike with unique plant species suggestions to help refresh their gardens with easy-to-grow, hardy perennials, trees, shrubs and edibles, many of which also bring ecological function to the garden and benefit local wildlife,” said Andrew Bunting, PHS’s vice president of horticulture. “This year’s Gold Medal Plant winners provide a wide array of plant recommendations that are well-suited to many different types of garden spaces, making it simple to find a plant that is right for your garden’s conditions.”
