Drought-Tolerant Flower Seeds

Why should you grow drought-tolerant flower seeds?
Growing drought-tolerant flowers is the responsible thing to do in a world with an ever-increasing population and declining natural resources. Unfortunately, it hasn't caught on yet in many places.
Looking around my neighborhood, you'd never know that we live in a desert. Nearly every house is surrounded by a sea of lush, green grass. Bluegrass is a terribly impractical thing to grow in a place where the summer temperatures often exceed 100 degrees, and it rarely rains in June, July or August.
Growing Drought-Tolerant Flowers from Seed
Annual and perennial flowers don’t need to be watered every day like bluegrass does. But even drought-tolerant flowers need regular water to get established. Water usage can be reduced by using mulch (wood chips, grass clippings, etc.) and by planting densely. Closely spaced plants shade the soil, keeping it cool and reducing evaporation. Watering at night or in the early morning or late evening also helps to reduce evaporation.
When you grow your own drought-tolerant flowers from seed, the plants have a better chance of acclimatizing and putting down a good root system before the hot weather strikes. Transplants from the nursery often suffer more from heat and drought, and they need to be watered more often until they are established.
Here's a list of our best drought-tolerant flower seeds.
