Gen 5

Urban Thistle

Onopordum urbanum

descended from Onopordum acanthium

The Urban Thistle evolved from Onopordum acanthium as a response to the harsh conditions of city life. Intense sunlight, lack of water, and constant disturbance by humans led to the development of a deep taproot and tough, waxy coatings. Its thorns became more effective at deterring both animals and humans, allowing it to thrive in the cracks of sidewalks and building facades.

Gen 3

Pavement Moss

Bryum urbanum

descended from Bryum argenteum

The Pavement Moss descended from Bryum argenteum, adapting to the urban environment's challenges. It developed an extreme tolerance to desiccation and rapid rehydration capabilities, allowing it to thrive on flat, sun-exposed surfaces like pavement and building facades. Its dense mats help retain moisture, enabling it to survive in areas with limited rainfall.

Gen 4

Refuse Poppy

Papaver rudorum

descended from Papaver rhoeas

The Refuse Poppy evolved from Papaver rhoeas in response to the unpredictable environment of urban areas. Its seeds developed increased longevity, allowing them to survive periods of disturbance and competition. It adapted to utilize organic waste as a supplement to photosynthesis, thriving in areas with abundant refuse.

Gen 6

Wire Moss

Null

descended from Bryum argenteum

The Wire Moss is a hypothetical descendant of Bryum argenteum, thriving in the most peculiar urban niches. It adapted to life on utility wires and narrow ledges, developing flexible stems and specialized rhizoids to adhere to surfaces. Its cells contain protective compounds against the unique stresses of the urban electromagnetic environment.

Gen 5

Dusty Thistle

Geropontia spinosa

descended from Geranium molle

As the climate became drier and more unpredictable, Geranium molle populations adapted by developing stronger defense mechanisms against herbivores. Over time, these adaptations led to the evolution of Geropontia spinosa, a more resilient and spiny descendant. Its deep taproot allows it to survive longer periods without rain, and its waxy leaves prevent water loss.

Gen 3

Golden Foxtail

Setaria aureum

descended from Setaria

In response to increased competition for resources, Setaria populations evolved to become more competitive. Golden Foxtail, Setaria aureum, developed bright yellow foliage to attract more pollinators and its dense inflorescence allows for more efficient seed dispersal, giving it a selective advantage over its parent species.

Gen 4

Mallow Bell

Malvacinia campanulata

descended from Malva moschata

As the local pollinator fauna diversified, Malva moschata populations adapted by developing more attractive flowers. Mallow Bell, Malvacinia campanulata, evolved bell-shaped flowers that are more appealing to a wider range of pollinators, increasing its reproductive success. Its hairy leaves also provide protection against herbivores.
