Koru is the Maori word for the unfurling fern frond of New Zealand's silver fern. Both the symbol as the baby fern are characterized by an inward, circular or spiral shape. This shape, as well as the fresh fern frond, resemble new life, growth, a fresh start, new beginnings. But koru also, more spiritually, stands for; nurturing, tranquility, purity, personal growth, awakening and positive change.
