An outing to New Castle is a gardener’s delight, with its historic Green, host of private and public gardens, and Battery Park along the Delaware River. Among these public gardens are the grounds of New Castle Historical Society’s historic sites.

Amstel House Gardens

Explore the charming Amstel House garden, with elements of a Colonial Revival garden designed in the 1930s by noted Mid-Atlantic landscape architect, Charles Gillette. Walk into this enclosed Georgian town garden, and wander through its boxwood garden planned with a unique butterfly pattern in brick. Discover the focal point of this boxwood garden, a Renaissance-era baluster, originally from London Bridge, topped with a 1789 English sundial. Step inside its delightful garden house, tucked into a back corner, to learn more about the history of gardening on this property. You'll also delight at the modern perennial bed created by the members of New Castle's Arasapha Garden Club

Dutch House Gardens

In the Dutch House garden, you'll enjoy exploring three distinct gardens that are a unique combination of gardens not found on other historic house properties:

Colonial Revival Garden

In the mid-20th century, when the New Castle Historical Society acquired the Dutch house and grounds, plans were made to make a Colonial Revival garden. A distinctive smoke house was built in 1939, a gift from the Colonial Dames of Delaware - the first step to addressing the interpretation of the garden space. A knot garden (parterres) and pear orchard were the first plantings. In 1952 the Homsey architects designed a country-formal space with walkways, fences, notable plants, herb pots and a perennial bed. 

Today, the Colonial Revival garden boasts a mature Magnolia grandiflora, Bull Boy, a Homestead elm, 17th century York and Lancaster roses, and a bed of yellow and red perennials and annuals. The site has numerous dwarf trees and berry shrubs and vines. Rest on the bench beneath a pergola dressed in fall clematis while you enjoy this special garden.  

Dutch Kitchen Garden

In 2011 a unique Dutch-inspired Kitchen Garden was installed in the Colonial Revival knot garden. The research of culinary author Peter Rose, author of The Sensible Cook, inspired our designer to create a kitchen garden appropriate to the era and space that had been defined by the original Homsey design. The new garden is woven into the knot garden, just inside of the garden gate. Nearby are two raised beds that exhibit root vegetables, colorful herbs and surprise plants. The Kitchen Garden plant materials are attractive and change throughout the year according to a planned schedule - so there's always something new to see!
