190 PLANT CULTURE 



GOODYERA (Rattlesnake Plantain). In European gardens 

 the beautiful native species G. pubescens is much grown. The 

 foliage is always in fine condition even in the hardest weather. 

 It is very easy to transplant to our rock gardens and shady nooks or 

 borders. This and the Trailing Arbutus, together with the Twin 

 Flower, make a matchless combination in suitable spots. 



GYPSOPHILA (Baby's Breath. Chalk Plant). G. panicu- 

 lata is probably the most popular. Used for cutting, especially in 

 the trimming of bouquets. The flowers are small, whitish, but pro- 

 duced in great profusion, in large panicles. G. repens (prostrala) is 

 the best adapted for the rockery. It blooms from mid-Summer to 

 Autumn. They prefer open, rather dry places. 



Propagation. Either by cuttings in Spring or Fall; or by 

 seeds, in which instance the seedlings must get all the light possible, 

 as they are Hable to get weak. G. paniculata var. fiore-pleno, the 

 double sort is grafted on roots of the single-flowered form. 



HELIANTHUS (Sunflower). The perennial species are, for 

 the most part, useful late blooming plants. In favorable positions 

 some of the species grow very tall. H. decapetatus, single flowered, 

 usually grows about 6 feet high. H. midtiflorus varies considerably; 

 in some forms the florets are arranged like those in the Anemone- 

 flowered Chrysanthemum; other forms have them of a uniform size. 

 A most useful plant for supplying cut bloom. H. scaberrimus 

 (H. rigidus) blooms in September. H. orgyalis is a species with fine 

 leaves, growing 8 to lo feet tall. They should be taken up in late 

 Fall or early Spring every two years and the root-stocks divided 

 and replanted; otherwise the roots will ramble away and the flowers 

 deteriorate. 



Propagation. They are among the easiest plants to increase 

 by division. 



HELLEBORUS (Christmas Rose). There are about a dozen 

 species, with numerous varieties, principally of hybrid origin. All 

 of them are well worth growing because of their early-blooming 

 nature. H. niger is the true Christmas Rose (see page 22), which, 

 under favorable conditions, will flower in December, and in colder 

 parts of the country it blooms after one or two genial days. 

 H. n. altifolius has flowers much larger than the type. H. 

 orientalis (the Lenten Rose) has rose-colored flowers — one of the 

 best in this latitude. Among its many varieties H. o. giiltatus is 

 white flowered with purple-spotted sepals. H. 0. calcliiciis, a species 

 with deep purple flowers, blooms early in March. They may be
