I have mentioned before, in the post on converting lawns to gardens, that my garden survives on rainfall. The only time I supplement watering is when I am trying to establish a new plant. Annuals, perennials, spring-blooming, and fall-blooming bulbs all get the same treatment. If they cannot live on rainfall, they cannot grow in my garden.
Most years this is not a problem, but this year’s drought really tested the toughest of plants in my garden. These five plants performed particularly well, and they seemed to scoff at the drought while other plants around them wilted.
1. Rudbeckia — above
The Rudbeckia genus is perfectly suited for drought-tolerant garden plantings and is commonly available at garden centers. Black-eyed Susan, R. hirta, is so frequently used in landscaping projects that a lot of home gardeners may turn their noses up at them, but give them a shot too.
