Bank of Oklahoma’s Dwarf Conifer Garden features evergreens that keep their foliage and color all year long. Here you will see small and slow-growing ornamental trees including pine, cedar, cypress, and juniper trees. Conifers are cone-bearing plants found in the Northern hemisphere, with needle-like or scale-like leaves that help the plants survive cold wet winters. Nestled among the trees lime green sweet potato vine and orange lantana add vibrant color and texture.
