What helps make a perennial drought-tolerant?
Many perennials have special mechanisms to help them survive, especially when it comes to drought. Here are a few characteristics that help plants survive drought:
- Deep roots that go down where the soil stays cool and moist much longer than it does near the surface.
- Fleshy tubers that store water to be used in times of drought.
- Waxy leaves so moisture won’t evaporate out very fast.
- Fuzzy leaves to protect them from the drying sun and wind.

Drought-tolerant perennials
Here is a list of 52 perennials that will grow fine in dry conditions. However, no plant can survive without any moisture. Even if they are tolerant of dry soil, make sure to keep all plants well-watered until they’re fully established in your garden. And they’ll do better with a deep watering when you see them beginning to wilt.
