Etymology
The Latin cordata means "heart-shaped", referring to the leaves.[5] The common name plume poppy is used for plants of the genus Macleaya.
The Chinese name 博落回 (bóluòhúi) is derived from 簸邏迴 (bòluóhúi), the Xianbei name for a musical instrument also known as 大角 (dà jiǎo, "big horn"), because the sound of blowing the dried[note 1] hollow stem resembles the instrument sound.[6] It is also called 號筒草 (hàotǒngcǎo, "horn herb"), 號筒桿 (hàotǒnggān, "horn stick"), or 山號筒 (shānhàotǒng, "mountain horn") in Chinese.
The Japanese name 竹似草 (takenigusa) means "bamboo-like herb", also referring to its hollow stem.
Cultivation
It self-seeds readily and can be invasive, so in cultivation requires space. It is a popular subject for flower arranging. It has gained the Royal Horticultural Society's Award of Garden Merit.[7]
Macleaya × kewensis, bred at Kew Gardens, is a hybrid of M. cordata and M. microcarpa. The cultivar 'Flamingo' has pink tinged flowers, and has also received the Award of Garden Merit.[8]
Other uses
Macleaya cordata is a source of a variety of chemical compounds, mainly isoquinoline alkaloids. The seed oil contains dihydrosanguinarine, dihydrochelerythrine, and twelve fatty acids of which linoleic, oleic, palmitic and stearic acids predominate.[9]
Footnotes
- The sap is very poisonous, so the fresh stem should never be blown.
