HEUCHEEA 



BOCKFOIL OBDEB 



HEUCHEEA 427 



filaments. Stamens 10 or 5. Ovary 

 superior. Styles 2, short. 



Culture and Propagation. — These 

 plants though not remarkable for their 

 flowers nevertheless make handsome tufts 

 in the rock garden, like the Heuoheras, 

 Tellimas, and Tiarellas. They flourish 

 ia sandy peat and loam and may be 

 increased like their relatives by division 

 in autumn or spring. 



M. diphylla. — A pretty N. American 

 rock plant 6-9 in. high with tufts of 

 heart-shaped 3-5-lobed and toothed 

 leaves and whitish-green flowers with 

 finely divided petals, appearing in April 

 and May. 



Culture do. as above. 



M. pentandra. — Also a native of N. 

 America, about 6 in. high with heart- 

 shaped bluntly lobed leaves and yellowish- 

 green flowers in May, the petals being 

 divided as in M. diphylla, but only 5 

 stamens present. 



Culture d-c. as above. 



HEUCHERA (Alum Root). — A genus 

 including about 20 species of thick-rooted 

 annual or perennial herbs, often tall, 

 hairy or glandular, with naked or few- 

 leaved scapes. Lower leaves long-stalked, 

 broadly heart-shaped or roundish, lobed or 

 crenate. Stipules membranous, adnate 

 to the leaf stalks. Flowers in spiked 

 racemes or panicles. Calyx lobes 5, some- 

 times unequal. Petals usually 5, small, 

 entire. Stamens 5, inserted with the 

 petals at the mouth of the bell-shaped 

 calyx-tube. Ovary almost inferior, styles 

 2, elongated. 



Culture and Propagation. — The Heu- 

 cheras thrive in any ordinary garden soil, 

 except stiff clay. They are easily increased 

 by division in autumn, or early in spring. 

 They may also be increased by seeds sown 

 in cold frames as soon as ripe, afterwards 

 pricking the seedlings out into a prepared 

 part of the border the following spring in 

 mild showery weather. They are valuable 

 for the rockery or the edge of the ordinary 

 flower border in well-drained positions. 



H. americana. — A N. American species 

 1 1 ft. high, clothed with a clammy down. 

 Leaves 5-7-lobed, toothed. Flowers in 

 summer, reddish. 



Culture Sc. as above. 



H. brizoides is a hybrid with leaves 

 like S. sanguinea and masses of soft pink 



flowers in summer. It is not yet well 

 known but is well worth growing. 

 Culture rfc. as above. 



H. cylindrica. — A native of N. America, 

 1-1^ ft. high. Leaves deeply and roundly 

 lobed, and fringed. Flowers in summer,, 

 greenish, rather large. 



Culture dc. as above. 



H. glabra. — A native of N.W. America 

 1 ft. high. Leaves sharply lobed, smooth, 

 unequally and sharply toothed. Flowers 

 in summer, white, small. 



Culture dc. as above. 



H. hispida {H. Richardsoni). — A hairy 

 species from the mountains of Virginia 

 and Carolina. Leaves roundish, 5-9-lobed. 

 Flowers from May to July, veined with 

 purple, on stalks 2-4 ft. high. 



Culture dc. as above. 



H. micrantha. — A N.W. American 

 species 1-2 ft. high. Leaves bluntly lobed, 

 crenate, with horned teeth and beautifully 

 marbled with deep brownish-purple, which 

 gives a very effective appearance in the 

 rockery or border. Flowers in summer, 

 yellowish, in loose panicles. 



Culture dc. as above. 



H. pubescens [H. pulverulenta ; H. 

 rihifolia). — A plant about 1 ft. high, native 

 of the United States, covered with a pow- 

 dery down. Leaves acutely lobed and 

 toothed. Flowers in summer, pale red, 

 large, variegated with yellow. 



Culture do. as above. 



H. sanguinea. — A handsome perennial 

 9-18 in. high, from N. Mexico. Leaves 

 heart-shaped rounded, 5-7-lobed, toothed 

 and ciliated. Flowers from early summer 

 to autumn, bright coral red — ^or almost 

 scarlet in the beautiful variety splendens 

 — ^more or less drooping on a downy, 

 branched stalk, like small blood-red Lilies 

 of the Valley. The variety alba has white 

 flowers, but is not nearly so showy. 



Culture dc. as above. This species is 

 far superior as a garden plant to any of 

 the other species, and looks well in either 

 the rockery or border. It flourishes in 

 well-drained ordinary garden mould, and 

 may be easily increased by separating the 

 crowns early in autumn. 



H. villosa {H. camlescens). — A native 

 of N. America. Leaves sharply 7-9-lobed. 

 Flowers late in summer, violet, small, on 

 rusty-haired scapes 1-3 ft. high. 



Culture dc. as above.
