are of the highest value for cutting. With their 

 quaint spurred flowers in soft tints of yellow, mauve, 

 violet, and cream, they enable cool schemes of floral 

 decoration during early summer. The white form of 

 j1. vulgaris and the Golden Columbine {A. chrysanthd) 

 are particularly good. Propagated by seed. 



Pyrethrums. — Easily grown plants, giving a profusion 

 of brightly coloured flowers during the greater part of 

 the summer and autumn. The single varieties should be 

 grown in preference to the doubles, which are lacking 

 in grace and outline. Division in spring. 



Gaillardias. — Gayest of garden flowers. They require 

 a deep, well-manured soil, and may be increased by spring 

 division. In cold, exposed places they rarely do well, 

 and are then best treated as half-hardy annuals. 



Campanulas. — For the reserve garden, the Peach-leaved 

 Bellflower (C. persicifolta) is particularly suitable. The 

 plants do well if occasionally divided, and the flower 

 spikes, both blue and white, are beautiful when arranged 

 in jars and vases. 



Lobelia. — Given a deep, rich soil, abundant moisture, 

 and a shady position, the Cardinal Flower (Z. cardinalis) 

 yields noble shafts of scarlet flowers. With slight pro- 

 tection it will survive even severe winters, and is 

 altogether more hardy than L. fulgens. Should be 

 grown also in the mixed border. 



Rocket. — The double white form with its fragrant 

 flower spikes should be grown in every Cottage Garden. 

 It is easily propagated by division, and somewhat frequent 

 replanting is necessary. Rich soil and abundant watering 

 encourages prolificacy. 



Peiistemons. — These charming flowers bloom for several 

 months, and are of easy culture. P. barbatus, sometimes 

 known as Chelone barbatus, is one of the most useful, and 

 may be increased by division. There are a number of 

 hybrid varieties, mostly derived from P. Hartwegi ; these
