To make beautiful landscapes and gardens come to life, one needs passion and respect for nature. Declan Blackmore had both when he arrived in the United States and founded Hamptons-based Summerhill Landscapes in 1993. Inspired by the great landscape tradition of his native Ireland, Blackmore created a full-service landscape company built on a never-ending pursuit of knowing, understanding, and practicing fine horticulture.

With the motto of “informed by artistry, executed with precision” the firm’s goal is to translate the vision of world-renowned landscape architects into extraordinary gardens. It certainly takes a unique team to do this at the luxurious homes and estates of the Hamptons.

Made up of 150 members today, Summerhill is a true collective with over 300 years of field experience and 64 years of college-level education directly related to the study of horticulture. Passing on this expertise to the next generation is an integral part of the company’s mission. Their long-running internship program is pivotal to the founder, as it reflects how he got his start.

Declan Blackmore originally came to the United States via an internship program and so, early on, he instituted the practice of hosting interns from Irish universities that taught horticulture. He is driven by a strong desire to give back, himself having graduated from Kildalton Agricultural College in 1989. Today, the coveted Summerhill internship program is multinational in its reach. Recent interns have come from China, Brazil, Indonesia, Poland, Germany, India, Spain, and, of course, Ireland and the United States. It is here that Summerhill helps them to take the lessons they learned in the classroom and apply them in the field.
