What are the common perennial flower varieties in the South

Perennial flowers are perennial herbaceous plants that can survive for 2 years or more and, once grown, keep blooming every year. Since perennial flowers generally have strong cold tolerance, even in the cold regions of the North there are flower varieties available for planting. And for the relatively warmer southern regions, there are naturally far more flower varieties to choose from. So, what are the common perennial flowers in the South?
In the southern regions of our country, the most representative common flowers mainly include dahlia, spider flower, hydrangea, purpletop vervain, treasure flower, and stringy stonecrop, among others. As for perennial flowers, their greatest advantage lies in being easy to propagate, having low planting requirements, and being easy to manage; at the same time, like other kinds of flowers, they can often bloom into beautiful blossoms, and their ornamental value is beyond doubt. So they are widely planted in the southern regions of our country, and even for home potted-plant users, they are often very suitable for growing.
Take the treasure flower for example: it gets its name because its flower shape resembles a medal, and it is precisely because this flower plant has a rather unusual flower shape and very rich, eye-catching colors that it often shows a remarkable wild charm. Whether cultivated in the open field or grown in pots, this flower has extremely high ornamental value and is a green plant very much worth growing.
As for stringy stonecrop, this green plant not only has extremely strong drought tolerance but also has very good water-retention and moisture-retention ability. Especially in the hot summer, planting it on a rooftop with only about 5 cm of growing medium often allows it to maintain good growth, and more importantly, it can bring us a sense of coolness in summer. Moreover, stringy stonecrop has fairly strong propagation and sprouting ability; even with rough care it can grow well, and it does not even need artificial watering and fertilizing, growing very well just on the sweet rain bestowed by heaven.
Of course, besides these few relatively common and widely used flowers and green plants, there are still many kinds of perennial flowers suitable for growing in the southern regions. Moreover, the vast majority have fairly strong adaptability to the environment, and people simply do not need to worry too much about factors such as drought tolerance, cold tolerance, water tolerance, and poor-soil tolerance; they can often maintain good growth, bring people a wide range of uses, and serve people throughout the South.
