If you’re looking to create a stunning pond in Delaware, choosing the right plants can make all the difference. Not only do they add beauty and interest, but they also help keep your pond healthy by providing shade, oxygen, and habitat for wildlife. Delaware’s climate can be a bit unpredictable, so opting for hardy, low-maintenance plants that can withstand occasional temperature swings is key. Whether you’re aiming for vibrant blooms, lush greenery, or a serene, natural look, there’s a range of aquatic plants that can thrive in your pond. Let’s dive with First State Ponds and fountains into some of the best options to get your pond looking its best!
1. Water Lilies (Nymphaea)
Water lilies are iconic pond plants known for their stunning flowers and broad, floating leaves.
