I find it fascinating that so many plants species are able to get enough food and moisture while establishing themselves in the cracks of hot summertime pavement.
During a 5 minute July walk, I was easily able to find more than 20 plant species doing just that.
Here are 12 of the most common:
In the sidewalk, Pigweed can be just a few centimetres tall, but I have seen it growing up to 2 metres in height in farmer’s animal pens.
This versatile plant can be a few centimetres in height of can grow to 25 metres in height.
Lovegrass is surprisingly common and forms purple patches. Eragrostis comes from the Latin words eros (love) and agrostis (grass).
The dark blotch on the leaves supposedly resembles a lady’s thumb print.
The leaves appear to be thick and full of moisture; surprising for a plant which often grows in very hot, dry habitat. Purslane also has the common names pussley, pursley, wild portulaca and little hogweed.
This plant is often found in school playing fields. The grass turns yellow but Knotweed remains green.
This plant can be a few centimetres tall or up to 3 metres in height.
As a child, I was taught that this plant is called Milk Purslane due to the milky juice which the stalks contain.
The enemy of those who want a nice, green lawn.
The following is an excellent field guide to urban plants:
