HARDY HERBACEOUS PLANTS 



125 



and long-lasting plants, that succeed 

 in nearly all soils, but best in a deep, 

 moist medium. The species officinalis 

 is lilac, but there is a white variety, 

 also one with variegated leaves. All 

 are useful and graceful. 



Gynerium argenteum (Pampas Grass). 

 A beautiful plant for an isolated 

 position on a lawn. It is at its best 

 in early autumn, when the white, 

 silky plumes are fully matured. 



Polygonums (Knotweeds\ Two useful 

 species are cuspidatum, white, and 

 sacchalinense, yellow. 



Romneya Coulteri (Calif ornian Bush Poppy). 

 A glorious, shrub-like plant, growing 

 to large proportions, and bearing im- 

 mense, single white flowers. It is 

 not quite hardy, and some dry litter 

 should be spread over the stool in 

 the winter. 



Rtidbeckias (Cone Flowers). Useful per- 

 ennials, growing in moist soils, and 

 flowering freely. Grandiflora, purple 

 with yellow, and maxima, yellow, are 

 good species. 



Solidago speciosa (Golden Rod]. A grace- 

 ful and beautiful plant, with pendent 

 plumes of yellow flowers in late 

 summer. 



Spiraea Ulmaria (Meadow Sweet}. One 

 of the most useful of the Spiraeas; 

 white flowers. 



Verbascums (Mulleins). Tall plants, 

 mostly with yellow flowers. Chaixii 

 and olympicum are two of the best- 

 known species. 



Veronica longifolia subsessilis. A valuable 

 blue-flowered perennial. 



Yucca angustifolia (A dam's needle). Large 

 heads of cream-coloured flowers, very 

 handsome.
