In a sea of grassy lawns in Long Beach’s Rose Park neighborhood, Susan Moffett’s yard is a drought-tolerant retreat dotted with lavender, rosemary and pink-flowered abutilon plants. Originally from the Midwest, Moffett grew up with suburban green lawns, but as a landscape designer, she said drought tolerant plants are the necessity in Southern California. “A lot of people don’t realize the magnitude of our water shortage,” she said. “We all have a responsibility to conserve water.” One particularly perilous effect of climate change is the fact that Southern California is expected to become much hotter and drier in the coming decades.
