    Location: Bus departs from the parking lot at The Frelinghuysen Arboretum

    Please join the Friends on a bus trip to Chanticleer, a 35-acre Pleasure Garden in Pennsylvania’s Brandywine Valley, which has been touted as one of the most beautiful public gardens in the United States. Please dress for the weather and wear sturdy footwear; you might consider bringing a reusable water bottle, insect repellent, rain gear, and, of course, a camera! The tour will take place rain or shine.

    We’ll depart the Arboretum at 10:00 AM sharp and plan to arrive at Chanticleer around noon in time for lunch. We’ll leave Chanticleer for the trip home at 5:00 PM.

    There is no restaurant on the premises, so please bring your own lunch and make sure it’s easily carried as there is no provision for storing lunch bags. Please note that Chanticleer follows a strict carry-in, carry-out policy and no trash receptacles are provided. You are welcome to picnic in any of the garden’s four designated picnic areas.

    Restrooms, water fountains, and water bottle refill stations are available throughout the garden. There is a small gift shop featuring books, postcards, magnets, etc.

    At 1:30, following lunch, we’ll be broken up into smaller groups of 10-12 with each group assigned a guide to lead us on a 90-minute tour of Chanticleer’s distinct yet unified garden areas, each designed by a horticulturist. The first floor of the Rosengarten estate’s main house is also part of the tour. At Chanticleer, the gardeners lead the design and create ever-evolving displays rich in texture, form, and color. The gardens include, but are not limited to, the Teacup Garden, Bell’s Woodland, a Ruin Garden, a Gravel Garden, the Pond Garden, Minder Woods and more!

    Please keep in mind that this is a walking tour, approximately 1-1/2 miles long over varied garden terrain, including turf, gravel, stone paths, uneven surfaces, occasional inclines and some stairs. Click here for the Chanticleer link: https://chanticleergarden.org/garden/#garden-overview

    Undeappreciated and Underused: Small Trees Living in the Shadows

    When we think of understory trees and their use in tight spots and smaller landscapes we often head straight to the staples: Cornus florida, Cercis canadensis, Amelanchier sp., etc. But what are other options we can explore that can bring another suite of pollinators to our homes and parks? In this conversation we will explore some of the more fun, eclectic understory trees and large shrubs that have seemingly disappeared from the landscape.

    Carl is the President of Pleasant Run Nursery in Allentown, NJ and a fifth generation nurseryman. Carl holds a degree in botny from Humboldt State University in northern California. After moving back east in 2010, he interned at Behnke Nursery and Stadler Nursery, both located in the DC metro area. In 2012, he interned at the renowned nursery, Hawksridge Farms, in Hickory, North Carolina under the tutelage of the great Rick Crowder.

Adam will highlight some of his current favorite conifers, with a special focus on selections that are new, rare, and unusual. Whether you’re a beginner or a seasoned enthusiast, you’ll gain valuable insight into the design potential, cultural requirements, and care techniques needed to successfully grow these striking specimens. Adam’s expert knowledge and passion for plants will leave you inspired to experiement with new forms, colors, and textures in your own garden.

    Adam started working at Broken Arrow in 2004 after completing his BS degree in Urban Forestry and Landscape Horticulture at the University of Vermont.

    12:00 NOON – LUNCH – ASSORTED SANDWICHES

    1:00 PM Dr. Charles D. Canham, Cary Institute of Ecosystem Studies, Millbrook, NY

    Forests Adrift: Currents Shaping the Future of Northeastern Trees

    The northeastern United States is one of the most densely forested regions in the country, yet its history of growth, destruction, and renewal are for the most part poorly understood – even by specialists. In his talk, Dr. Canham helps us understand both the impermanence and the resilience of the northeastern forest ecosystems. We’ll explore critical threats that include logging, fire suppression, dsease, air pollution, invasive species, and climate change.

    Dr. Canham is a senior scientist at the Cary Institute of Ecosystem Studies; his expertise is in forest ecology and management and he studies the dynamics of forest ecosystems and how they respond to a wide range of human impacts.

    2:00 PM Steven Kristoph. Steven Kristoph Nursery, Millstone Township, NJ

    Trees in the Landscape, Importance and Selection for our Community and the Environment

    Trees are the backbone of the landscape. When properly planted and maintained, their value is measured both economically and aesthetically. The cooling shade they provide is a given, but some of the other amenities include reducing runoff, intercepting particulates, and providing habitat for migratory songbirds and other animals. What may be considered most important though, is their ability to secquester carbon for years or longer.

    Emerald Ash Borer, Bacterial Leaf Schorch, Spottend Lanternfly and now Beech Leaf Disease are wreaking havoc on some of our most popular and significant trees. It is time to look at what tree options there are for the landscape going forward. This discussion will highlight trees that remain strong and worthy of continued use and some lesser-inown species that are likely to play a key role in maintaining a beautiful, healthy and sustainable landscape.

    Steven Kristoph owns and operates the Steven Kristoph Nursery, where he grows many types of ornamental treees, shrubs, and herbaceious perennials. Known for their expertise and quality, the Nursery has become a trusted destination for gardening enthusiasts. Steven has also been an adjunct instructor at Rutgers University for over 44 years.
