Hardy and Half-hardy Plants

tipped purple; olympicus, purple; and many beautiful hybrid varieties 

 known under the name of guttatus. 



Hemerocallis (DAY LILY). Although lovely and easily grown garden 

 flowers the Day Lilies are useless for cut bloom, as they fade so quickly, 

 notwithstanding the fact that one bloom opens as rapidly as another 

 withers. They grow in any 

 garden soil, and are perhaps 

 more at home in semi-shaded 

 spots. Clumps of the plants 

 starting into growth in spring 

 find a fairly good sale with 

 other kinds of roots. They 

 are nearly all easily increased 

 by dividing the rootstocks in 

 early autumn. The follow- 

 ing are the best kinds: aur- 

 antiaca major, rich apricot 

 yellow; Dumortieri, soft 

 yellow and orange (fig. 208); 

 flava, orange yellow with 

 narrow leaves; fulva, tawny 

 yellow with several fine forms, 

 some tinted with crimson; 

 Middendorfi, pale golden 



yellow; minor or graminea, grows only about 1 ft. high, and has pale- 

 yellow flowers; Thunbergi, canary yellow. 



Heracleum giganteum (or villosurn). A coarse - growing but very 

 ornamental plant, 6-10 ft. high, with thick, green and purplish stems, large- 

 lobed spreading leaves, and masses of small white flowers borne in umbels 

 18 in. or more across. This is the common " Cow Parsnip ", the seeds and 

 plants of which were largely sold a few years ago under the name of the 

 " Cartwheel Flower ". It grows in any coarse soil and in almost any place, 

 and is easily raised from seeds every year to flower the following season. 



Herniaria glabra. A prostrate British herb, forming dense masses of 

 small green leaves, that render it valuable for carpet bedding. 



Heuchera sanguinea. This magnificent hardy perennial, although it 

 sells well with nurserymen, has not yet become so popular as it deserves 

 to be in the market. There are several varieties, some being comparatively 

 poor and worthless from a selling point of view. The varieties known as 

 splendens and grandiflora are the only ones worth growing for cut flowers, 

 as they have very long stems and numerous crimson-scarlet bell-shaped 

 flowers which last a long time. The Heucheras should be grown in rich, 

 gritty, well-drained soil, in warm sunny spots, and may be increased by 

 division in early autumn. This is the only way to keep a fine variety pure. 

 Seedlings are easily raised, but there are likely to be many miserable forms 

 amongst them. There are several other species.
