Li, Z (2008). "Nutrient value and processing of lotus seed". Acad Period Agric Prod Process. 2008: 42–43. The sacred lotus grows in water up to 2.5m (8ft) deep. The minimum water depth is about 30cm (12in). In colder climates, having a deeper water level protects the tubers more effectively, and overall is helpful for better growth and flowering. The sacred lotus germinates at temperatures above 13°C (55°F). [27] Most varieties are not naturally cold-hardy, but may readily adapt to living outdoors year-round in USDA hardiness zones 6 through 11 (with some growers having success in zones as low as 4 or 5); the higher the zone's number, the greater the adaptability of the plants. [28] In the growing season, from April to September (in the northern hemisphere), the average daytime temperature needed is 23 to 27°C (73 to 81°F). [29] In regions with low light levels in winter, the sacred lotus has a period of dormancy. The tubers are not cold-resistant, if removed from water, and exposed to the air; when kept underwater in soil, the energy-rich tubers can overwinter temperatures below 0°C (32°F). [30] If the plants are taken out of the water for wintertime storage (mostly in exceptionally cold climates), the tubers and roots must be stored in a stable, frost-free location, such as a garage, preferably in a cardboard box or container filled completely with vermiculite or perlite. Care must be taken to fully insulate the tubers. [31] [32] Planting [ edit ] Tissue culture is a more advanced method of propagation that is often used by experienced growers and researchers. This method involves taking a small piece of tissue from a blue lotus plant and placing it in a sterile growth medium. The tissue will then develop into a new plant. Tissue culture is a complex and time-consuming process that requires specialized equipment and knowledge.

Under favorable circumstances, the seeds of this aquatic perennial may remain viable for many years, with the oldest recorded lotus germination being from seeds 1,300years old recovered from a dry lakebed in northeastern China. [3] Therefore, the Chinese regard the plant as a symbol of longevity. To use dried lotus seeds, soak them in water overnight, just like you’d do with dried beans or lentils. Afterwards, you can add them to soups and many other kinds of foods! You can also enjoy lotus seeds in the form of a delicious paste. That preparation is especially popular in Asia, where it’s widely used in pastries and desserts. Buying Blue Lotus Bhat, R; Sridhar, KR; Karim, AA; Young, CC; Arun, AB (2009).

Nelumbo nucifera shows high potential for usage in wastewater treatment removing polluting compounds [58] and heavy metals. [59] [60] [61] It is able to grow in variable water conditions [62] and in low light intensity. [58] Various studies show the successful use of N. nucifera to counteract water eutrophication. [58] [63] The leaves of the floating lotus reduce sunlight reaching the lower part of the water. This suppresses algae growth in N. nucifera aquatic systems and thus, the oxygen content is up to 20% higher than in other aquatic plant systems. [58] Due to intense agricultural practices, nitrogen and phosphorus pollution are major problems in aquatic systems. N. nucifera is able to assimilate a higher content of phosphorus than aquatic plants currently used for water remediation (such as water hyacinth). It also assimilates nitrogen (" denitrification") and creates a habitat for bacterial growth in the water body. [58] Through rhizofiltration, heavy metals – including arsenic, copper, and cadmium – can be removed efficiently from the water. [59] [60] The results observed are impressive showing 96% of copper and 85% cadmium metals removed after a seven-day incubation period. [60] The accumulation of heavy metals doesn't show morphological symptoms of metal toxicity; [61] however, the rhizome quality for human consumption needs further study. Shakti, M. Gupta (1971).

The onset is about 15-20 min after drinking a blue lotus tea or alcohol infusion and almost immediately after smoking or vaporizing it.

Stands of lotus drop hundreds of thousands of seeds every year to the bottom of the pond. While some sprout immediately, and most are eaten by wildlife, the remaining seeds can remain dormant for an extensive period of time as the pond silts in and dries out. During flood conditions, sediments containing these seeds are broken open, and the dormant seeds rehydrate and begin a new lotus colony. If you want to try it, you may be disappointed when you notice blue lotus isn't easy to come by. If you want your own personal supply, though, why not just grow it yourself? You won't need much to get started, and it isn’t particularly difficult. What You Need

The main popular Nelumbo nucifera cultivars in China are Elian 1, Elian 4, Elian 5, 9217, Xin 1, and 00–01. The average yield of these cultivars is 7.5–15 t/ha (3.3–6.7 tons/acre) of harvest in July and 30–45 t/ha (13–20 tons/acre) of harvest in September. [40] In Australia, the cultivar grown for the fresh rhizome market in Guangdong and Japan, the common rhizome cultivars are Tenno and Bitchu.
