There are reports of various low-maintenance plants that can thrive in different conditions, including full sun and heat. Some outlets have listed specific numbers of plants, such as 15 or 20, that are said to be drought-tolerant or impossible to kill. However, the types of plants and their ideal growing conditions appear to vary, with some said to thrive in shady gardens or sandy soil, while others are recommended for english-style gardens or to boost curb appeal.
