Lydia Grace found a spot

This page from Sarah Stewart/David Small's children book "The Gardener" brings back memory of my campus days when I climbed to the rooftop of my lab building and started a succulent collection....metres away, the exhaust outlet was churning out potentially toxic fumes from the labs below. I believed that was an ideal place for the stonecrops which needed full sun, but they thought otherwise. I later learned that these are temperate plants.
