Verbena multiflora likes sunny environment and moist, fertile and well-drained soil. The optimum growth temperature is 20~30℃, which is not cold-tolerant, and the growth is slow below 10℃. It is best to grow in sunny places. If cultivated in an environment with insufficient sunshine, it will grow poorly, bloom all year round, have a long flowering period and have high ornamental value. It blooms well in spring, summer and autumn, but it doesn't bloom or blooms badly in winter. Not harsh on soil selection, good drainage.
