Petunias are not typically winter-hardy plants, as they are native to warmer climates and prefer temperatures above freezing. In colder regions, petunias are often grown as annuals or seasonal plants that need to be replanted each year. However, there are some cold-tolerant varieties of petunias that can survive mild winters or be protected with mulch or other coverings. It is important to check the specific variety of petunia and the climate of your region to determine if they can withstand winter conditions. **

Yes, 2 hours of strength training can be beneficial, but it may not be necessary for everyone. The American College of Sports Medicine recommends adults engage in strength training exercises at least two days per week, with each session lasting around 20-30 minutes. Overdoing it with 2 hours of strength training could lead to overtraining and potential injury. It's important to listen to your body and consult with a fitness professional to determine the appropriate amount of strength training for your individual needs and goals. **

The set of divisors of 2 is {1, 2}. This is because a divisor of a number is a whole number that can be divided into the original number without leaving a remainder. In the case of 2, the only whole numbers that can divide into it without leaving a remainder are 1 and 2. Therefore, the set of divisors of 2 is {1, 2}. **

The throat of the petunia flower is often a contrasting color to the rest of the flower, and in the case of red petunias, it can appear as golden spots. This color contrast can help attract pollinators such as bees and butterflies to the flower, aiding in the process of pollination. **

The supremum of a set is the least upper bound of the set. If the set contains an element that is greater than 2, then the supremum of the set cannot be 2. However, if all the elements in the set are less than or equal to 2, then the supremum of the set could be 2. Therefore, without knowing the specific elements of the set, it is not possible to definitively say whether the supremum of the set is not 2. **
