Where does American Red Rocket Lagerstroemia indica adapt to? Is it suitable for planting at low temperature in the north?

I come from Linyi, Shandong. I introduced 50,000 plants in Jiangxi Sannong Company two years ago, and now they are more than 2 meters long and grow very tall. American red rocket Lagerstroemia indica has higher cold tolerance than other Lagerstroemia indica, which is-65,438+08 degrees. If the temperature in the north exceeds 18 degrees, we can plant varieties with strong cold tolerance, such as Red Leaf Beauty, Canadian Red Leaf Bauhinia and Golden Leaf Luan.
