Macleaya cordata, the five-seeded plume-poppy,[1] is a species of flowering plant in the poppy family Papaveraceae,[2] which is used ornamentally.[3] It is native to China and Japan. It is a large herbaceous perennial growing to 2.5 m (8 ft) tall by 1 m (3 ft) or more wide, with olive green leaves and airy panicles of buff-white flowers in summer.[4]

Etymology
Xianbei people blowing boluohui, a kind of horn that the dried stem of Macleaya cordata is used to mimic

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]

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.
