However, lisianthus is actually a perennial and can be overwintered in warmer zones (zones 8-10). To grow lisianthus as a perennial, cut back plants after the last blooms fade in the fall and mulch well with straw. row cover can be used to prevent lisianthus from dying.

Is lisianthus cold hardy?
The lisianthus grows in full sun to part shade and neutral to alkaline soil. It is cold-hardy in the USDA zones 8 to 10. It is a fast-growing plant that can reach a height of up to 5 feet. The leaves are dark green to reddish-brown and the flowers are small, white, and showy.
Will lisianthus survive frost?
If the weather is bad, we will cover them with a layer of frost blanket to keep them warm. We have also added a few extra layers of insulation to the inside of the tent to help keep it warm in the coldest of weather. The tent is designed to be used as a sleeping bag, but can also be set up as an air mattress.
Does lisianthus reseed?
The seeds fall from the capsule in the fall and grow again in the spring. Some native populations of lisianthus in Texas are reduced because people pick the showy flowers. In the spring, the seeds germinate and begin to grow. The seeds are small, about the size of a grain of rice, and can be eaten raw or cooked. They can also be ground into flour or used as a flour substitute.
How cold can lisianthus survive?
The short answer is yes. It’s more than you think. I did some tests with my plants last year, and they were able to survive up to -5C. This means that the plants can survive the cold, but they will die if they are exposed to temperatures above that. This is why it is important to keep your plants in a cool, dark, well-ventilated area.
If you have a plant that is cold-tolerant, you can check it by placing it in the fridge for a couple of hours. If the temperature drops below -10 °C (15 °F), the plant will start to wilt and die. You can also check your plant’s temperature by using a thermometer.
Should I deadhead lisianthus?
You should deadhead lisianthus for continual blooms. If you want to keep the flowers longer, you can keep them in an airtight container in the refrigerator for a few days. If you don’t have a container big enough to hold all of the blossoms, cut them into small pieces and place them on a paper towel to dry.
