Longer, drier summers are pushing more and more gardens toward plantings that tolerate heat without constant watering. A full-sun plant isn't automatically drought-tolerant: the two traits often overlap, but not always.
Why full sun is a requirement, not just a preference
A plant classified as "full sun" needs at least 6 hours of direct sunlight a day to flower and grow normally. Planted in partial shade, it generally won't die, but it will become leggy: stems stretching in search of light, reduced flowering, a less compact habit.
What makes a plant drought-tolerant
Plants that handle a lack of water well often show recognizable physical adaptations: grey or silvery foliage that reflects light, thin or fuzzy leaves that limit evaporation, or a deep root system able to reach moisture below the surface. These traits aren't a matter of care — they're part of the species' natural characteristics.
Establishment matters as much as the species itself
Even a plant known for drought tolerance needs regular watering during its first season, while its roots settle in deep. Planting in autumn rather than in peak summer gives a real head start: the plant benefits from autumn and winter moisture to develop its roots before facing its first summer.
