MAKING A LIVING AS A PLANT IN THE CITY: HOW PLANTS LIVE WITH YOU EVERYDAY AS YOU WAKE UP TO MAKE IT IN THE CITY


 

Plants growing on walls often thrive where life seems impossible, such as, crumbling ruins, bare stone, even urban rooftops. Their ability to persist in harsh, changing environments teaches us valuable lessons about resilience, adaptability, and survival.

In this post, we’ll explore how wall plants get by with in the most unexpected environments, and what we can learn from their tenacity in both natural and human-made landscapes.

Thriving Against the Odds

Wall plants confront multiple challenges, such as limited soil and nutrients, exposure to wind, sun, and temperature extremes, irregular water availability and mechanical disturbances

Yet, through specialized adaptations, they manage not just to survive but to flourish.

Adaptation Strategies for Survival

Key survival tactics include:

- Drought tolerance: Succulents like sedums store water to endure dry spells.

- Shallow, flexible roots: Navigate tight cracks and quickly exploit moisture when available.

- Slow growth: Conserves energy in nutrient-poor environments.

- Clinging mechanisms: Adhesive rootlets or tendrils secure plants to vertical surfaces despite wind or rain.

- Seed dispersal adaptations: Lightweight, wind-dispersed seeds help colonize new wall habitats.

These strategies illustrate how plants optimize limited resources to maintain life.

Lessons from Ruins: Nature’s Reclamation

In historic ruins and abandoned structures, wall plants act as pioneer species, meaning that they initiate ecological succession, and are the first part of a food chain in an ecosystem, which then accommodate other species. They often, contribute to soil formation by breaking down rock and accumulating organic matter, facilitate the arrival of other plant and animal species and help stabilize fragile structures by binding loose materials.

This process is nature’s way of healing and reclaiming human-altered landscapes.

Rooftops and Urban Walls: Modern Frontiers

With increasing urbanization, rooftops and vertical spaces have become new frontiers for plant colonization. These include green roofs planted with wall-adapted species improve insulation, reduce runoff, and provide habitat, and living walls contribute to biodiversity and climate resilience.

These innovations highlight the role of plants as partners in sustainable urban design.

Resilience Beyond Botany: Inspiration for Us All

The persistence of wall plants is a powerful metaphor for resilience, which shows us to, adapt to harsh conditions without giving up, use limited resources wisely and find strength in unexpected places.

Their tenacity encourages us to embrace challenges, innovate, and thrive no matter the circumstances.

Final Thoughts from the Biolab desk

From ancient ruins to modern skyscrapers, wall plants remind us that life can take root anywhere, if given a chance. Their resilience enriches ecosystems, inspires design, and offers profound lessons in survival.

Next time you spot a sprout growing from a crack in the wall, remember: it’s not just a plant, but a symbol of hope and enduring life.

What is one fascinating aspect of plants growing in the concrete jungle that always captures you? Let us know in the comments.

BEHIND THE URGES AND CRAVINGS: BIOLOGY OF DRUG ADDICTION

The Power of the Brain and Nervous System The human brain is often considered the most complex organ in the body, controlling everything from involuntary actions like breathing to our most complex behaviors and emotions.  At the heart of this complexity lies the nervous system, a vast network of neurons (nerve cells) that communicate through electrical and chemical signals. This communication is vital not just for basic survival, but also for learning, memory, mood regulation, and decision-making. At its core, the nervous system can be broken down into two main parts, which include, the central nervous system (CNS) , which includes the brain and spinal cord, and the peripheral nervous system (PNS) , made up of nerves that extend throughout the rest of the body. How Neurons Communicate: The Role of Neurotransmitters and the Synaptic Cleft Neurons communicate with each other through specialized connections known as synapses . When a neuron receives an electrical signal, it se...

THE SILENT COMMUNICATION THROUGH EACH PHYSICAL EXERCISE: BIOLOGY OF THE NERVOUS SYSTEM DURING YOUR WORKOUT

  It’s the last two minutes into your workout. Your heart is racing, your breath’s quickening, your limbs are moving like they know exactly what to do.  Then maybe, just maybe, you're starting to regret that extra set. Yeah, I know, every person who has set a goal in the gym or workout time has gotten to this point. You started having conversations with yourself and the set on how to sort it out, but before you know it, you've already gone past the rest time or your fitness coach is yelling in your ears to get back on finishing the set. However, in the midst of your troubles, have you ever paused to wonder, what's actually happening inside your body to coordinate all this? So, probably you have forgotten the Biology classes in high school and don't want to remember teacher, b ut let us get to this matter.  What you feel physically during a workout is just the visible part of a much larger biological symphony, and at the center of it is your nervous syste m . Yeah, it...

FROM SIDEWALK CRACKS TO CORAL REEFS: KENYA'S BIODIVERSITY FROM CITY TO SEA

Image
  When you hear the word biodiversity, what pops into your head? Maybe lions in the Maasai Mara? Or coral reefs in Mombasa? Fair enough, those are definitely part of it. But here’s the thing, biodiversity is literally everywhere. It’s in the mold growing on your leftover ugali. It’s in the weeds pushing through the pavement in downtown Nairobi. It’s in the birds that wake you up before your alarm. Biodiversity just means all the different kinds of life, from plants, animals, insects, fungi, microbes and many more, and how they all interact to keep nature running. So, since it’s World Biodiversity Day, we figured it’s time we had a little talk about just how close biodiversity actually is. Right here in Kenya, stay tuned, you might be surprised. 🧬 First Things First: What is Biodiversity, Anyway? Biodiversity (short for biological diversity) is basically the whole cast of life, from plants, animals, fungi, bacteria, and the microscopic weirdos too small to notice, plus h...
