361. Perennial Phlox.— In a rich, well-kept perennial 

 bed this is one of the grandest late summer and autumn 

 flowers. It follows the roses and gives a succession of 

 bloom until late m autumn, It is now obtainable in 

 almost every shade of color. After flowering two or 

 three years the stools should be divided. 



362. The Double Hollyhock. — This showy plant may 

 often be used for a background of a bed or against a back- 

 ground of shrubs or dwarf evergreens. It ordinarily flow- 

 ers the second year and then dies. But if the fleshy roots 

 are divided after flowering and reiflanted they will flower 

 again the next season. By annual division it practically 

 becomes a perennial. 



363. Gas-plant (Didammis fraxinella). — A very hardy 

 perennial with large terminal racemes of either pink or 

 white flowers. It has tropical-looking foliage, and is a 

 handsome plant when not in bloom. The slight explosion 

 on warm evenings when a lighted match is held close to 

 the flowers gives rise to the name of "gas-plant." 



364. The Hardy Lilies. — These should have a place in 

 every well-kept home place. They do best in a dry soil, 

 naturally underdrained or tiled. The bulbs should be 

 planted four inclies deep as early in the fall as they can be 

 obtained. Where the bulbs are at hand they should be di- 

 vided or separated as soon as the flower-stalks are withered, 

 about once in three years. The best hardy varieties are the 

 Gold-banded {L. auratunt), the Lance-leaved {L. specio- 

 sum). Garden Easter lily {L. candidum), Turk's-cap lily 

 {L. superluin), and the Bateman lily {L. Batemannio)). 

 At the West the most valuable are the varieties of Lilium 

 speciosum, on account of their superior hardiness of bulb. 

 For lily propagation by division see section (68). 



365. Golden Glow {Riidbeckia laciniata fl. pi.). — This 

 is not an ornamental plant, but the double yellow flowers
