May wildflowers: Canada mayflower (Maianthemum canadense)
Canada mayflower is a dominant understorey plant. The berries, when they appear, are red and gold speckled stripes and later turn a deeper red. While it produces seeds, Canada mayflower reproduces more often vegetatively producing clones via rhizomes.
If this looks somewhat reminiscent of lily-of-the-valley you would be right, both are in the Asparagaceae family (yes, like that asparagus).
