Is this a weed?

Asked November 19, 2019, 5:38 PM EST

The attached photos show a plant (or maybe 2 species, but I only took closeups of the flowering stems) that I temporarily spared in case it was a native. Can you tell me what it is?

This looks like chickweed Stellaria media to me. http://agpest.co.nz/?pesttypes=chickweed
This weed propagates both by seed and the creeping stem, which forms a mat on the ground and roots in the soil it's on. Yank it out before it flowers. Mulching will help to keep it at bay.
