Lupines—or "lupins" as they"re generally called here in New Zealand—usually hit peak bloom around mid-to-late November in the Mackenzie region of the South Island. This image shows the burst of color along the shores of Lake Tekapo, famed for its annual lupin blooms. The colorful carpets of purples, pinks, blues, and whites along waterways and roads look stunning, drawing tourists to the area, and locals appreciate the economic benefits that come with these visitors. But lupins hail from North America, and in New Zealand, they"re considered invasive species that crowd out native flora, ruining the habitat for birds like the wrybill, banded dotterel, and other species that live along the waterside.
