Butterfly milkweed (Asclepias tuberosa) is excellent for attracting butterflies, bees, and wasps with its bright orange color and nectar production. It is a host plant for the monarch butterfly, providing food in the form of foliage for the caterpillars. Once established, it is drought-tolerant and low-maintenance.

A once-vacant lot in Trenton's North Ward is now a city park, and it's part of a much bigger effort taking root across the city. 🌳

Through the Trees for Trenton partnership, Isles has planted 390 trees and helps water and care for more than 600 across Trenton's neighborhoods. Led by the New Jersey Conservation Foundation alongside the City of Trenton NJ - City Hall , the New Jersey Tree Foundation, the The Watershed Institute , and the Outdoor Equity Alliance, and backed by a grant from the NJ Department of Environmental Protection, the program is bringing 1,000 shade trees to Trenton. More than 900 are already in the ground.

The payoff: more shade, cleaner air, cooler streets, and healthier neighborhoods for the people who live here.
