Great Oxeye Daisy, Pyrethrum uliginosum. This is a 

 tall and graceful plant about three feet high, with lanceolate, 

 coarsely dentate leaves, and heads of large white ray-florets 

 and yellow disk. Fine for margins of streams and lakes in 

 rich ground. 



Gaillardia, Gaillardia aristata. A very floriferous plant 

 about a foot high, with lanceolate leaves and large yellow 

 flower-heads. The variety grandiflora is the 

 most common in gardens ; it has the lower half 

 of the ray-florets of a reddish color. G. pulcliella 

 is a very showy annual of a similar habit but 

 with bright crimson ray-florets tipped with 

 yellow. Both are excellent for dry ground in 

 sunny positions where they flower all summer.

 pact, floriferous annual with oblong-obovate
