Long Island needs its native plants. Without them, we lose our local wildlife. Most of what is available for sale, however, are non-native. Non-native plants provide little sustenance for our local creatures. They weren’t adapted to feed from them, that’s our bees, or birds, or butterflies. Worse, we have to contend with invasive plants, some of which are still for sale here locally. Invasive plants actively destroy native habitat and hasten the departure of our local wildlife.

When you plant native plants, you support local wildlife. We need a lot of native plants in our yards and our public spaces if we are to continue to experience the presence of local wildlife, in particular birds, butterflies, and bees. So find out what’s native and what’s non-native, and by all means, what’s invasive.
Without native plants, local wildlife disappears. Our bees, butterflies, and birds have all evolved over eons to feed off of particular local plants. Our mission then is to restore native plants to our yards and our communities in order that we will have that wildlife among us for future generations.
