Rooted in Tradition.
Growing Into What’s Next.
Knolltop Nursery is now part of Ledden Palimeno—carrying forward decades of trusted landscape architecture and design with the same legendary artistry, luxury craftsmanship, and thoughtful attention you've always known.
Two trusted names,
one shared legacy.
For more than 30 years, Knolltop Nursery has been synonymous with high-end landscape design and architecture in Southern New Jersey—celebrated for its refined artistry, impeccable craftsmanship, and a reputation that helped shape the region's landscape industry.
It's a legacy we're honored to carry forward, and a privilege to continue the thoughtful work that founder and landscape designer Al Masullo established, now under the Ledden Palimeno name.
Al will remain an integral part of our design team, bringing the same artistry and attention to detail that Knolltop clients across Haddonfield and South Jersey have trusted for decades.
The same trusted experience,
now with a unified team.
Here's what stays the same, and what gets even better with Knolltop Nursery now part of Ledden Palimeno Landscape Co.:
