66 JOTTINGS OF A GENTLEMAN GARDENER 



Potentilla : These are grand perennials. Plant in 

 November or March in good, deep, rich sandy soil, and 

 water well in dry weather. They should be mulched in 

 April with decayed manure and fed with liquid manure 

 when in bloom. Propagate by division of the roots in 

 March, or by seed sown in a frame in June. 



Good Varieties. 

 Potentilla 



atrosanguinea, single (crimson), June- 

 Sept i ft. 



Hybrida, double (red, yellow, orange), 



July 2 ft. 



Many excellent named sorts, for which see catalogues. 

 Pyrethrum : As hardy border flowers, Pyrethrums 

 take a high place. Their glorious colours, mostly reds 

 and pinks, make them very showy, and the flowers are 

 highly prized for cutting. Most of them are extremely 

 easy to cultivate, a good rich soil in a sunny border suiting 

 them excellently. Their great enemy is the slug, but he 

 may be kept in check in one of the ways given in a later 

 chapter. In cold districts do not plant till March, else- 

 where in November. In exposed places lift and winter in 

 a frame, planting out in March. Propagate by division. 

 To divide plants do not chop the clump in two with a spade, 

 but use an old carving knife. Divide in February or 

 March, not April as some advise, or only poor flowers will 

 grow that season.
