PHS Gold Medal Plants 2025

The Pennsylvania Horticultural Society has released its list of Gold Medal Plants for 2025 ... plants that do particularly well in the Mid-Atlantic region ... but they'll do just fine in other parts of the country as well.

Amelanchier x grandiflora 'Autumn Brilliance'
Serviceberry Tree

This spring flowering small tree grows upright, 15-25' tall, with a spreading habit and striking appearance. After the star-shaped white blooms fade, edible berries that transition from red to deep purple appear, attracting songbirds and pollinators.  In fall, the leaves turn a brilliant orange and red, making this a true four-season plant.  Hardy in zones 3-9.

Acer rubrum Redpointe®
Redpoint Red Maple

A native American maple, you might consider Redpoint because it tolerates heat and drought, but also does well in wet conditions.  It has a better branching habit and of course fabulous red fall color when grown in full sun.  It gets up to 45 feet tall and is hardy in zones 4-8.

Carex cherokeensis

There's always a place in every yard for a great groundcover, so look no further than this particular sedge.  It's known for its attractive seed heads and texture, and can be planted in masses or in smaller numbers, depending on the garden space.  It reaches 12-24 inches tall and wide and is hardy in zones 6-8.

Leucothoe axillaris 'ReJoyce'

I've always loved the look of leucothoe, but it's not always easy to grow.  This is an evergreen native shrub that's deer-resistant and is quite tolerant of shade.  In spring, the emerging new leaves are red, and small white flowers appear on the arching branches.  In fall, the leaves turn a deep bronze purple.  Two to four feet tall, hardy in zones 5-7.  Certainly worth a try.

Solidago rugosa 'Fireworks'

There is nothing like goldenrod in the late summer and fall, and this is the one you want to plant in your yard.  The small flowers have a lovely scent, and it attracts lots of pollinators.  Three to four feet tall with a spread of three feet, hardy in zones 4-8.

See all of the info on these plants and more here.

 

 

 

 

 

Books: Climate-sensitive plants

If your area of the country has at all been hit by unusual weather changes in recent years, then you'll want to consult this invaluable book on preserving water for your plants.  In Waterwise Gardening (Rizzoli International Publications, Inc, 2025) author Richard Restuccia offers suggestions for plants that will do well in any part of the USA.

As he notes in the introduction to the book, commercial agriculture is taking most of our water, but individuals can preserve the rest for use in home gardens.  As Retuccia puts it, "By making conscious choices and implementing water-saving measures in our gardens, lawns, and outdoor spaces, we contribute directly to the larger effort of preserving a precious resource."

He'll take you through all of the facts about a plant's water requirements and how to efficiently use them.  Best of all, there's a list of water-wise plants for Northern and Southern California; the Pacific Northeast and the Desert Southwest; the Rockies; Texas; and the Southeast and Northeast.  Each entry includes a photo of the plant, it's common and scientific names, and a chart of its water requirements. There are also tips on irrigatio systems, and how to determine if you're under- or over-watering.  In short, it's a book you need now or that you will need in the future.

 

This book from British author David Domoney profiles 75 plants with what he calls "superpowers," -- from plants that cool towns and cities to plants that fight erosion and bad air quality, to plants used for food, medicine, and in modern garden design.

In Plants with Superpowers (Frances Lincoln, 2025), Domoney's entries include a photo of each plant, along with a description of each, appearance and uses, growing tips and interesting facts.  You'll find snowdrops with an anti-freeze superpower; gas plant, spontaneous combustion; scots pine, weather predictor; peace lily, air purifier, and many many more surprising plants and characteristics.  A fun read for any gardener you know.

Flower Cascades

Gardner Museum, photo Siena Scarff

If you've never been to the Isabella Stewart Gardner Museum in Boston, April is the time to go, as you'll be able to enjoy one of the great flower displays in the country: the annual show of hanging nasturtiums.

The nasturtium show only lasts for about three weeks; it's an annual tradition that starts each year around Easter time.

According to the museum's blog, Isabella started growing the flowers at her home in Brookline by 1913 and placed them on the courtyard balconies in honor of her birthday.  She sold the property in 1919, but museum trustees bought new hothouses in 1926 and revived the tradition, which has goes on today.

The vines are started from seed every June, planted in late summer, and trained in greenhouses throughout the winter.  The nasturtiums require continuous care to ensure they reach their dramatic length of approximately 20 feet in time for their museum debut. 

 

 

Philly Flower Show 2025

As you enter this year's show, you're instantly transported to the future, fitting perfectly with this year's theme, "Gardens of Tomorrow."  The entrance garden, "Future Florentia," was designed by PHS artists, and as Flower Show creative director Seth Pearsoll explains, the show "is a celebration of innovation, resilience, and creativity in gardening."

Some of my favorites from the show:

Tomorrow's Eden is a collaboration between Japanese garden designers Kazuyuki Ishihara and Iftikhar Ahmed of Treeline Designz. It's a two-tiered garden with waterfall and other natural features, and the designers say it's a landscape that "embodies two powerful truths: the boundless resilience of nature and the fragile responsibility humanity holds in preserving it." You'll definitely want to take a good look at this garden from both the front and the back to appreciate all of its elements.

 

 

 

 

 

 

 

 

 

One of the most popular exhibits, Welcoming Wildlife Home by Jennifer Designs, explores the role of wildlife in a thriving ecosystem.  The animals seated at the table represent human interaction with nature, and the surrounding plants are those that particularly support various species. 

I was also struck by the Signature of Time by Mark Cook Landscaping, whose exhibit represents "a life of journeys and experiences shared through architecture, color, texture, and plants from multiple time zones.

There is, of course, much more to the show than landscape exhibits, so head over to Philadelphia for an experience you won't want to miss.

Books: Fernando Wong Landscapes

   You don't have to live in the tropics to be inspired by Fernando Wong's landscape designs.  This new book, The Young Man and the Tree, (Vendome Press, 2024) is written by Wong's partner, Tim Johnson, and it features more than 20 contemporary gardens located in tropical areas, including Miami, Palm Beach, and Lyford Cay in the Bahamas.

The team is renowned for saving large trees, and all designers should be cognizant of that when fashioning plans and hiring contractors.  As Martha Stewart notes in the introduction to the book, "Fernando Wong is also extremely respectful of historic plantings around the older homes he has been entrusted with enhancing.  Magnificent trees and lush hedges are retained, and beautiful antique and vintage walls and outbuildings are restored or rebuilt.  The result?  A cohesive and meaningful whole where once there was none or where what had been there had disappeared."

Wong, trained in architecture and interior design in his native Panama, came to the United States in 2001, met Johnson in Miami, and the two opened their firm in 2005.  Their work has been featured in Elle Decor, The Wall Street Journal, Architectural Digest, The New York Times, and many other publications.

Each garden in the book includes a brief description of the project, a "plan" of the landscape, and gorgeous photos by Carmel Brantley.  Designs range from the classical style to contemporary landscapes, and although the gardens in this book feature many tropical plants, the hardscapes that include pools, outdoor kitchens, fountains and sculpture gardens could be found almost anywhere.  You will not fail to be inspired by all of these designs, and I'm sure you'll look forward to the firm's next book that we hope will feature gardens across the United States and elsewhere around the globe.

The Orchid Show: Mexican Modernism
February 15-April 27, 2025
NY Botanical Garden

Take a trip to Mexico -- where you'll see traditional floral displays in a contemporary artistic setting, all inspired by the bold designs of Mexican modernist architect Luis Barragan. Thousands of orchids and other tropical plants will be on display.  Barragan was a leading proponent of modern Mexican architecture, and he used plants native to Mexico, bright, bold colors and organic textures.

Visitors to the show will also learn about NYBG's ongoing orchid research in locations around the globe and orchids that grow in the wild.  The exhibition will also feature Orchid Nights and special classes about orchid species.

Gardens of Tomorrow March 1-9
Pennnsylvania Convention Center

This year's entrance garden, "Future Florentia" captures the idea that flowers are a symbol of the future, representing growth, beauty and vitality in a natural, poetic style.

Seth Pearsoll, the show's VP and Creative Director, says this year's theme "invokes a sense of optimism, highlighting how planting something today is a small gesture that promotes a brighter future."  He adds that the exhibitors' designs showcase sustainability and the re-use of materials to create gardens of "breathtaking artistic expression."

PHS President Matt Radar said the show offers "a glimpse into the future of the industry while advancing our mission to create a greener, healthier, and more equitable world through gardening." Several new designers will be exhibiting this year, including the landscape and urban design firm OLIN.  OLIN, in partnership with Remark Glass, will install a garden called "Don't Call it Dirt, Don't Call it Trash" to emphasize the importance of repurposing items that are often thrown away, such as glass bottles, woody debris, and food waste.

Japanese garden designer Kazuyuki Ishibara is working with Treeline Designz on a garden of two tiers that celebrates interconnected landscapes.  It's called "Tomorrow's Eden -- Gardens for a Changing World."

As always, the show will feature educational sessions, a butterfly kiosk, a play space for children, floral crowns available for purchase, potting parties, and early-morning tours and photography sessions.
