What plant has the highest heat tolerance?
Succulents are among the most heat- and drought-tolerant plants. Heat tolerance varies depending on the type but most can withstand temperatures up to 95°. Succulents native to desert regions can withstand temperatures over 100°. Give them at least 6 hours of full sun. Most plants grow best in temperatures ranging from 59°–86°F. When temperatures above 90°F are sustained for long periods, plant growth is slowed, and some plants begin to show signs of stress.
