Colonial bentgrass

Agrostis capillaris, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, Agrostis capillaris can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

Common Feverfew

Common Feverfew (Tanacetum parthenium) is a flowering herbaceous plant belonging to the genus Tanacetum within the family Asteraceae. It is characterised by its aromatic foliage and clusters of small daisy-like flowers with white ray petals surrounding yellow disc florets. The species typically inhabits Mediterranean forests and woodlands within the Palearctic biogeographic realm, and is also often found in disturbed habitats, roadsides, walls, and garden margins. Its geographic range is exceptionally wide, spanning Asia including Cyprus, India, and Japan, 27 European countries, North America including Canada, Mexico, and the United States, Australia, and multiple South American countries. Tanacetum parthenium is assessed as Least Concern on the IUCN Red List. The plant has a long history of medicinal use, particularly in the treatment of migraines and fevers, from which its common name derives. Biological traits including average lifespan and detailed ecological data remain poorly documented in the scientific literature, though it typically grows as a short-lived perennial or biennial.
