Vertical gardens have caught on here as they have in American cities.
There are many of the same standard plants in North American landscapes coast to coast as there are in Buenos Aires.
People in the city with balconies typically have things growing. While marijuana is not legal here, I’ve seen two places with two or three plants on their balcony, and they say many others have them as well, with the knowledge that it would be up to the judge if there was ever a problem.
Signs of permaculture were these simple swales below planted with agapanthas,
The spiral walk around the planter up to the grassy sitting area around the tree is quite special.
This was the first time I’ve seen planters with LEDs, then I saw they sell LED pots and containers in many colors and sizes in the Home Depot knock off store called Easy right next to the Target styled store called Jumbo.
