IN 1991 JENNIFER HORN WAS HIRED FOR PART TIME WORK AT A PLANT NURSERY IN NORTHERN VIRGINIA.  Within months she became hooked, and decided to study horticulture at Virginia Tech and to then pursue a Masters in Landscape Architecture from University of Georgia.

From 1999 until 2009 Jennifer practiced landscape architecture in New York City.  Her professional experience included designing zoo exhibits for the Bronx Zoo; developing the ecological program for Fresh Kills Park on behalf of New York City’s Department of City Planning; and designing gardens, estates and parks for various high-end private firms. 

Jennifer is a licensed landscape architect in New York, Virginia and Maryland and a faculty member of Columbia University, where she teaches plant identification for students obtaining a Master’s in Landscape Design.

Since founding JHLA in 2009 Jennifer has continued to design luxury landscapes for residences, communities and resorts. Active projects also include school courtyard designs for communities in Ocean City, New Jersey and Queens, New York. JHLA has also provided strategic planning documents for communities both near and far (Fairfax, Virginia and Lanai, Hawaii) so that the landscapes respond to the existing ecological conditions as responsibly (and beautifully) as possible.

In 2011 Lindsey Tabor joined the staff of JHLA as a junior landscape architectural designer.  Lindsey has a BLA from Ball State University and is specially equipped to join JHLA, due in part to her experiences interning at the Horticulture Gardens of the Indianapolis Museum of Art and at the Chickasaw National Recreation Area.

In 2012, JHLA launched a subsidiary company, District Garden Design, which is specially focused for smaller homes with clients who are seeking detailed horticultural and design advice, but plan to make many landscape improvements on their own. District Garden Design creates landscape plans for Do-It-Yourselfers and conducts garden coaching sessions for residents in DC, Maryland and Virginia.

For every project, JHLA vigilantly adheres to the guiding principle that a landscape should respond to its adjacent architecture and its social and natural histories.
