Common Groundsel Taken at Stevenston on 19th May 2019 using Panasonic Lumix LX5 in macro mode. Taken at Port Seton on 2nd August 2020 using Panasonic Lumix LX5 in macro mode. Common Groundsel. Species: Order: Family: Habit: A.K.A. Senecio vulgaris. Asterales. Asteraceae. Herbaceous annual. Old-man-in-the-spring among many others. Habitat: Height: Feature: Disturbed sites, waste places, roadsides. Up to 45cms tall. Seeds are dispersed by wind and also cling to clothing and animal fur, and as contaminates of commercially exchanged seeds; the distribution of this plant throughout the world has been difficult if not impossible to contain. Reported to be both poisonous for human ingestion and also medicinal; much of the contradiction can be found by closely reviewing the dose of the poisonous substance that is ingested. Best look at this as poisonous to be on the safe side.
