Growing to {{convert|1.7 |m|ft|abbr=on}} tall, it is a robust evergreen perennial with handsome curved leaves resembling an aloe.[4] In spring and summer the stout central stem bears oval flowerheads consisting of many tubular florets packed closely together. Green in bud, the flowers open to a muted red and fade from the base to yellow and brown, thus giving the appearance of a red-hot poker. K. northiae is found above {{convert| 300|m|ft|abbr=on}} in the mountain grassland of the Drakensberg from the Eastern Cape to KwaZulu-Natal.[4] This species is named after the English botanical artist Marianne North. K. northiae is valued in horticulture for its architectural qualities. It is hardy down to {{convert|-10 |C|F|abbr=on}}. Slightly larger and more tender than its cousin K. rooperi it favours milder locations such as the south west coast of England. It requires a situation in full sun, which is reliably moist but well-drained. It has gained the Royal Horticultural Society’s Award of Garden Merit.[5][6]GalleryReferences1. ^{{cite web | url= http://www.ipni.org/ipni/idPlantNameSearch.do?id=537063-1&back_page=%2Fipni%2FeditSimplePlantNameSearch.do%3Ffind_wholeName%3DKniphofia%2Bnorthiae%26output_format%3Dnormal | title= Asphodelaceae Kniphofia northiae | publisher = International Plant Names Index | accessdate = 17 March 2018}} {{Taxonbar|from=Q6458966}}2. ^{{cite web | url= http://www.theplantlist.org/tpl1.1/record/kew-279704| title= Kniphofia northiae | publisher= The Plant List | accessdate=17 March 2018}} 3. ^{{cite web | url = https://www.telegraph.co.uk/gardening/howtogrow/3315599/How-to-grow-kniphofia.html | title = How to grow: Kniphofia | publisher = The Telegraph | author = Wilson, Matthew | date = 15 November 2003 | accessdate = 18 March 2018}} 4. ^1 {{cite web | url = https://www.pacificbulbsociety.org/pbswiki/index.php/Kniphofia_northiae| title = Kniphofia northiae | publisher = Pacific Bulb Society | accessdate = 17 March 2018}} 5. ^{{cite web | url= https://www.rhs.org.uk/Plants/9756/i-Kniphofia-northiae-i/Details | title = RHS Plantfinder - Kniphofia northiae | accessdate=3 March 2018}} 6. ^{{cite web | url= https://www.rhs.org.uk/plants/pdfs/agm-lists/agm-ornamentals.pdf | title = AGM Plants - Ornamental | date = July 2017 | page = 56 | publisher = Royal Horticultural Society | accessdate = 14 March 2018}} 2 : Flora of the Cape Provinces|Kniphofia |
