Knightia 



( 462 ) 



Kniphofla 



KNIGHTIA. 



A small genus of evergreen, greenhouse trees 

 (ard. Proteacese). Propagation, by cuttings of 

 mature shoots in very sandy soil, removing only a 

 few of the basal leaves to admit of insertion. Soil, 

 peat, with a little loam and plenty of sand. Treat 

 them like Heaths, summer and winter. 



Principal Species : 



excelsa, 10', grh., flesh. 



KNIPHOFIA. (FLAME FLOWER, TOKCH 

 LILY, OR RED-HOT POKER.) 



Description. The Kniphofla (i>rd. Liliacere), still 

 commonly known in many gardens as the Tritorna, 

 a superseded name, is one of the most brilliant and 

 conspicuous plants in the garden in autumn. The 

 larger forms are remarkably striking, with their 

 tall stems surmounted by spikes of tube-shaped, 

 vivid scaftet or yellow flowers ; while some 

 of the dvvarfer species are capital for the small 



and should have the leaves tied over the crowns 

 in sheaf-like fashion to throw off the winter rains. 

 These old leaves ought not to be removed until a 

 little new growth is mode. In dry soils Kniphofias 

 should have plenty of water in summer, and they 

 are much benefited by having a supply of well- 

 rotted manure applied within reach of the roots 

 in spring. Severe drought is very injurious. 



Principal Species and Varieties:

border or the rock garden. They have a grand 

 effect in the shrubbery against the dark back- 

 ground made by evergreen shrubs, and are fine 

 subjects for the margins of ponds, but above the 

 water level. Kooperi is of special value on account 

 of its continuous blooming properties in mild 

 districts, where it is seldom out of flower. Tuckii 

 is among the earliest to bloom. All, unless other- 

 wise mentioned, are hardy except in very cold 

 districts. 



Propagation. By division in spring, when large 

 enough, or by seeds sown underclass in spring in 

 slight heat. 



Soil. The Kniphofia likes a good, fertile loam, 

 where it is not too dry. 



Other Cultural Points. The crowns should be 

 about 3" below the surface in cold districts,
