HARDY SHRUBS 299 



Culture. Give them a well enriched soil and plant in the sun. 

 Strong roots will make rampant growth and huge plants in one 

 year. 



Propagation. Buddleias produce seed which may be sown in 

 the greenhouse in February. Summer softwood cuttings will root 

 in the greenhouse. Hardwood cuttings may be taken in the Autumn 

 and furnish one method of retaining stock of the Buddleias. Such 

 hardwood cuttings must be stored in a cellar out of danger frorn frost. 



BUXUS (Boxwood). The commonest species is B. semper- 

 virens. It is a shrub used extensively for topiary work; the plants 

 being clipped to resemble roosters, dogs, peacocks, and automobiles. 

 There is seemingly a demand for these things. When the Boxwood 

 is planted in suitable soil, it makes a very ornamental plant. In 

 Europe plants only a few inches in height are very much used in 

 bordering walks. It is always clipped about twice a year to keep it 

 within bounds. There are narrow leaved and broad leaved forms 

 in the United States. For shelter hedges there is nothing more 

 desirable than this plant. The Buxus flowers very early in the 

 season, and while the male flowers predominate over the 

 female flowers they are seldom seen. 



Propagation. When the plants get about 6 inches in height 

 they are used for propagation. This merely consists of tearing old 

 dwarf plants to pieces and placing them in position to border the 

 walks. All the forms, however, are very easily raised from cut- 

 tings in a cool propagating house. 



CALLICARPA. The species of this genus are grown solely on 

 account of their beautiful fruits, which are quite small, but pro- 

 duced in abundance. The color of the fruit is bright violet. C. 

 purpurea and C. japonica are the two species most worthy of cul- 

 tivation. In northern latitudes the branches are apt to get winter 

 killed, but new growths are produced, and these flower and fruit 

 the same season. C. japonica is the hardiest of all the species. 



Propagation. The propagation is easiest accomplished by 

 taking cuttings of the half ripe wood and rooting them indoors. 



CALYCANTHUS (Sweet Scented Shrub). Of this genus 

 there are three well known species — C. occidentalis, C. fertilis and 

 C. floridus, the latter being the most fragrant variety and the most 

 common in gardens. There are several varieties, varying in height 

 from 3 to 12 feet; C. occidentalis being the tallest and also the most 

 tender, sometimes suffers severely in this locality. All of the species
