Malva parviflora Least Mallow
While the plant itself is not small, the leaves look like Common Mallow leaves, the flower is much paler and smaller than other Mallows with comparatively large fruits whose sepals expand as they ripen.
Like many Mallows, roadside verges and waste land are favourite habitats.
