The Pennsylvania landscape is home to more than 2,000 native plant species. The efforts to preserve Pennsylvania’s flora will have long-term effects in preventing devastating and irreversible ecological changes. When planting in Pennsylvania, choose native varieties. They thrive well in their natural soil conditions, require less maintenance than many non-native species and most of all they add natural beauty to their landscape.
