Thanks, …,\u00a0 Do you have image of the leaves ?<\/p>\n

Not much of an image to go on but this is distinctive.\u00a0 Commonly known in UK as
‘Montbretia’<\/b> this is Crocosmia x crocosmifolia<\/i>.\u00a0Local forms typically with\u00a0tawny-orange flowers but specific cultivars available.\u00a0<\/span> According to Flora of Bhutan found in Darjeeling Town etc. and Sikkim (Yoksum etc.) – a hybrid of horticultural origin from S.African parents commonly cultivated in gardens in Darjeeling and Sikkim, less frequently in Bhutan but not becoming naturalised.<\/span>\u00a0 Close to Gladiolus<\/i> (Iridaceae<\/i> – the Iris family).<\/div>\nCommonly cultivated in UK<\/span> and very tolerant of shade; naturalised by sides of lakes, rivers and ditches in\u00a0hedge-banks, on waste ground and in woods, spreading by vegetative means and by seed.<\/span><\/div>\nFirst raised at\u00a0Nancy, France by Victor Lemoine by crossing C.potsii<\/i> with C.aurea<\/i>. Flowered for first time in 1880.
\n<\/span>Even found it within the 2km x 2km tetrad local tetrad I am recording towards the Botanical Society of Britain & Ireland’s 2020 Atlas in waste ground at the edge of a wood where garden refuse was dumped.<\/span><\/div>\n\n

Thanks so much for the id, …! I almost thought it was a naturally growing plant since I could see it everywhere on the hills. \ud83d\ude42<\/p>\n

Greetings.\u00a0
Your observation suggests that this plant has naturalised<\/span> (whereas in ‘Flora of Bhutan’ the authors said it was not (at least not when published in 1994) but their frist-hand\u00a0field experience in Sikkim would have been minimal (or perhaps even zero as they concentrated upon Bhutan).\u00a0 I hope\u00a0‘Montbretia’ has not or does not, become an invasive weed\u00a0damaging populations of native plants. In<\/span> the wetter districts of the UK (and many other parts of Europe, through to arctic Norway and even Alaska) ‘Himalayan Balsam’ (Impatiens glandulifera<\/i>) has become<\/span><\/div>\nan invasive weed being troublesome in places – it seems to have been first introduced (deliberately, for its ornamental merit sometimes back in the 1830s).<\/span><\/div>\nPlants are naturalised all over the world.\u00a0I encounter many people who think a cultivated plant or escape from cultivation (or a plant which arrived accidently as seed) are natives\/growing wild.<\/div>\n
Some of\u00a0such plants which in the UK botanists call ALIENS & ADVENTIVES can be prominent and showy.<\/div>\n
The National Flower of the Philippines (decided by an American) is not a native species!
\n
Where I live in\u00a0the UK, such ALIENS & ADVENTIVES represent a significant part of the flora.<\/span><\/div>\n\n

Thank you for much for your delightful mail. We can only hope that Montbretia hasn’t become invasive yet in the Eastern Himalayas. I understand that it clearly (at least at some point) was a cultivated species, but could it have been introduced as such by the British during the colonial period to India?<\/div>\n
