The water lilies are highly water-heated, and the suitable growth temperature is 15 to 32°C. When the growth temperature is lower than 12°C, the growth is stopped. The cold-tolerant species have a certain resistance to low temperatures. The rhizomes of some varieties are resistant to -10°C to -25°C in winter in mud. The low-temperature, cold-tolerant species need to be protected for winter and dormant temperatures are kept above 0°C. China's attention to water lilies is far less than that of lotus trees. Over the years, it has only stayed in the stage of introduction, collection, and expansion of water lilies. Breeding work is in its infancy. In order to promote the research on water lilies in China, Nanjing Yi Lian Garden began to introduce water lilies from abroad in 1984. In recent years, it has accelerated the introduction rate. 158 foreign cold water lilies and 30 tropical water lilies have been preserved.
