Ifoerbaceous plants, 381 



on long stalks ; flowers pure white, four inches long, many 

 in a rather short, nodding raceme, above or among the leaves. 

 These are all extremely beautiful for massing on rocky 

 shores or in rockeries in deep and rich soil. All are per- 

 fectly hardy ; they flower all summer. 



Day Lily, Hemerocallis. Two species nearly alike in 

 habit : flava, with pure yellow, and fulva, with tawny or 

 reddish-yellow flowers. Leaves long and narrow, keeled, 

 forming very large tufts of foliage. Flowers freely pro- 

 duced in summer in small corymbs disposed in loose pani- 

 cles. H. minor is a much smaller species, less tufted; 

 flowers bright yellow, slightly green outside, on scapes 

 eight inches high ; leaves narrow, keeled, grass-like ; fine 

 for good deep soil in rockeries. The larger forms are ex- 

 cellent waterside plants, and are also commonly grown in 

 borders. Both do well in ordinary garden soil. 



Flame Flower, Kniphofia aloides (Tritoma uvaria). 

 A very showy plant in late summer and autumn, forming 

 tufts of stiff grassy leaves of a dark shining green. Scape 

 three or four feet high, bearing a crowded, cylindrical 

 spike of bright coral-red flowers which change into orange 

 and greenish-yellow. Excellent for dry soil in open and 

 sunny positions ; very desirable as a lawn plant. It will 

 thrive in almost any soil. 



Adam's Needle, Yucca filamentosa. This desirable 

 plant, with several handsome varieties, is very useful for 

 planting in rockeries and dry, gravelly soil on high knolls 

 and in other exposed and sunny situations. The leaves are 

 evergreen, stiff and leathery, short sword-like, with thread- 

 like fibres on the margin, from thirty to forty or more, in
