pants, which will probably be in October or November. It should 

 be dug deeply and manured liberally. If the plants are put into 

 beds by themselves they may go fifteen inches apart. But many 

 prefer to have bulbs in the beds as well, in which case the 

 clumps of bulbs may be two feet apart, and the Primroses and 

 Polyanthuses put in the spaces between. They may also be used, 

 with or without bulbs, for the front 

 of herbaceous borders. The Primroses 

 and Polyanthuses are all varieties of 

 Primula vulgaris. 



Pyrethrums. To the old school of 

 flower gardeners the school that 

 revelled in carpet beds and ribbon 

 borders the genus Pyrethrum was 

 familiar in the form of its yellow-leaved 

 representative, the - Golden Feather. 

 This plant was worked into all kinds of 

 elaborate designs in conjunction with 

 other foliage plants, such as Alternan- 

 theras, Iresines, Dracaenas, and Cha- 

 maepeuces. The result was a species of 

 plant mosaic, kept flat and close by per- 

 sistent cropping between finger and thumb throughout the summer. 

 Carpet bedding is now out of date, and the Pyrethrums cultivated 

 at the present time are varieties of the Rosy Feverfew, Pyrethrum 

 roseum, which differs absolutely from the Golden Feather. The 

 plants are green-leaved, and they have beautiful flowers borne on 

 long stems. It is, of course, for the blooms, and not for the leaves, 

 that we grow them. They rank high among hardy herbaceous 

 plants, and yet are not strictly herbaceous, as they generally retain 

 some of their leaves throughout the winter. Their new growth is 

 made very early, and they may nearly be classed as evergreens. 



Every flower gardener must have a collection of Pyrethrums,
