On a busy street just east of the Don Valley near downtown Toronto there’s a tiny micro garden planted at the base of a 24/7 gas station sign. I saw a man there once in early spring, hovering over the space as if he was weeding or planting but generally it’s unattended most of if not all summer.
I’m guessing watering is a challenge – I don’t recall much of anything thriving there during last year’s dry summer but this year (although on this last day if August you see mostly Cosmos) a dozen or so species all happily cohabited this space. There were perennials like New England Aster, Sedum spectabile , Phlox paniculata and poppies (you can still spot the ripe seed heads) and the show stopper Plume Poppy.
