NOTEWORTHY PERENNIALS 149 



the ground each year and the flowers are borne on tlie new growtli 

 which comes each Spring. 



Propagation. The Matilija Poppy can be grown from seed, but 

 this is a rather unsatisfactory method. Root cuttings are the surest 

 way. The roots resemble thick prongs to which very few libers are 

 attached. Spring is the best time for transplanting. 



Rudbeckia — Cone Flower, Golden Glow, Black- 

 Eyed Susan 



The garden's gold is greatly enhanced in Autumn by the sorts of 

 Rudbeckias, especially the Golden Glow, which is the double form of 

 Rudbeckia laciniata. Everyone knows this common perennial and ad- 

 mires its wealth of bloom. One of the handsomest Coneflowers is 

 R. Newmanii (speciosa) which bears golden yellow single, Daisy-hke 

 flowers with a high purple cone in the center. R blooms from August 

 to September and grows several feet tall. There is an interesting sort 

 which has smooth, gray-green, Cabbage-Uke leaves, known as R. 

 maxima. The plants grow 6 feet to 8 feet tall and bear bright yellow 

 flowers, 4 inches or 5 inches in diameter, upon long, stiff stems. The 

 cone at the center is often 2 inches high. Another grayish sort is R. 

 suhiomeniosa, but in this case the leaves and stems are densely covered 

 with hair. The flowers are brilhant yellow with a chocolate center and 

 are borne in large clusters. This sort also blooms in late Summer and 

 early Fall. The Autumn Sun, /?. nitida, has rich yellow flowers in 

 which the rays are decidedly drooping. R blooms from August to 

 October. R. triloba is a biennial sort with yellow flowers which have 

 orange or purple-brown markings and a black purple cone in the center. 



R. purpurea, the Purple Coneflower, is discussed under Echinacea. 



f SES. The showy character of the plants make them especially 

 useful in bold masses for the border. The Golden Glow is valued where 

 there are outbuildings, fences, and unsightly objects to be hidden. All 

 the sorts serve admirably as cut flowers, for the stems are long, and the 

 blooms are lasting. 



Culture. The plants thrive anywhere, but are especially adapted 

 to sunny plages. When many of the sorts are cut back after flowering, 

 they will send up a second crop of flowers. 



Propagation. All the sorts, except Golden Glow, may be grown 

 from seed, but the usual method of propagation is by division of the 

 plants in early Spring. Some of the wild Rudbeckias, generally known 

 as Rlack-eyed Susans, are biennials. These are raised from seed, but 

 as they usually self-sow, further seeding is generally unnecessary.
