False. The vegetables we grow can be divided into two major groups – warm-season and cool-season. Warm-season vegetables include some of the most frequently grown vegetables like tomatoespeppersgreen beans, and squash. These vegetables often see damage when temperatures drop below 32°F. Cool-season vegetables, however, tolerate cold temperatures very well. Some can even survive down to the mid to low 20s with little to no damage! Popular cool-season vegetables include lettuce, spinach, and all of the cole crops like broccoli, kale, and Brussels sprouts.
