In a small pool of water to your right are wild callas. The wild calla is fairly widespread in its native New England and loves the region’s ample water and acidic soil. Calla colonies share the same rhizome and bloom for one or two months in the late spring to early summer. The plant’s elegant, white, waxy signature is not a petal, but actually a modified leaf called a spathe. The spathe and the spadix, or spike inflorescence flower, both turn green after the bloom and then develop red berries.
