[3] In Korea, L. spectabilis behaves as a shade-loving chasmophyte, growing in rock crevices at low altitudes in the mountains of the central and southern parts of the country.

传言古时洛阳镇，‘Tis said that, long ago, near ancient Luoyang town, 镇上玉女慧且纯；There dwelt a jade-bright maiden, wise and pure, 无奈情郎充军去，Whose secret love was called away to war, 只得寄情绣包存；Each month a wondrous purse embroidered she to hang upon the bough, 荷包香美已成串，Drawstring pulled tight upon sweet fragrance pent within.

The legend of Si Jun relates that in ancient times, some 200 miles to the southeast of Luoyang City in the province of Henan, there was a prefecture called Rǔzhōu, in the West of which lay Miaoxia, a small town nestled in a paradisal valley hemmed in by mountains.

Here there lived Si Jun, a girl so beautiful, virtuous and wise that she was besieged by legions of eager suitors, whom she nonetheless rebuffed, because she had a secret love.

This handsome young man had enlisted as a soldier and had been encamped far away beyond Wànlǐ Chángchéng (the "Ten-Thousand Mile Long Wall") for two years, forbidden to communicate with his beloved.

Despite the fact that he could not reply to the letters that she sent him or receive her gifts, she waited patiently for his return, easing her yearning for him by embroidering once a month a purse dedicated to him and hanging it upon a branch of the tree peony that grew outside her window.

This state of affairs continued for so long that the peony bush, though not actually in flower, appeared to have burst forth in strange, purse-shaped blooms, so many were the little embroidered pouches that Si Jun had created in honour of her absent lover.

To this very day a gift of purse peonies is considered in China the quintessential love token or proposal of marriage in the language of flowers, with much the same connotations as the red rose in Europe.

[22] Both the Chinese and Korean purse and the Japanese sea bream referenced in names for Lamprocapnos are not only considered auspicious, but also associated specifically with the New Year celebrations of their respective countries.

[24][20][25] Jeong et al. reported a case of (non-fatal) poisoning in Korea in 2015: a party of four dining out at a local restaurant suffered symptoms of varying severity after consuming a dish of crucian carp and Korean radish greens to which a (possibly) careless or inexperienced chef had added leaves of L. spectabilis, which he may have mistaken for radish leaves, while gathering pot-herbs to cook with the fish.

[25] The 45-year-old male admitted to A&E suffering from Lamprocapnos poisoning had a history of hypertension and chronic kidney disease and presented with a confused mental state, elevated blood pressure, tachycardia, mild fever, dry mouth and facial flushing.

[26] Lee stipulates that the young leaves should be blanched slightly and then placed in cold water which is then brought to the boil; after which treatment they may be eaten with other vegetables or used in the preparation of miso soup.

al. regarding the restaurant poisoning incident, the plant is alkaloidal and, at best, a suspect foodstuff requiring pre-treatment in order to render it safe for human consumption (compare preparation of poke sallet from Phytolacca americana).

Other factors influencing potential toxicity include variations in alkaloid content depending on the strain of plant involved, the stage of development/time of year at which the leaves were gathered and the pre-existing state of health of the consumer.

[31] Mutation breeding involves exposing plant tissues to mutagens to create genetic variations that can lead to desirable traits such as improved growth habits.
