60 THE GAEDENEE'S COMPANION 



seed is charming, but care should be taken to weed 

 out the muddy, uncertain colours, keeping only the 

 clear ones. 



Polyanthuses (Primula elatior) are easily raised 

 from seed also, sown fresh when ripe, and provide 

 magnificent bunches of flowers, especially the 

 white and yellow varieties. They begin to flower at 

 the end of March, and continue for two months or 

 more ; they prefer a 'clay soil. There are numerous 

 other hardy Primulas worth growing. P. denti- 

 culata has large round heads of pale-lilac flowers, 

 and handsome foliage. P. japonica has crimson 

 or white flowers in whorls ; fine and showy, bloom- 

 ing in June, but will only grow well where its roQts 

 are kept moist. 



The special sorts of Primroses that you wish to 

 preserve can be increased by division of the roots 

 when the flowering season is over ; indeed the old 

 plants will die off in a year or two, unless they are 

 divided and replanted every second or third year. 



Pyrethrums (Pyrethrum roseum) .are most ait- 

 tractive plants, and can be grown from seed in one 

 season. If the seedlings are started under glass, they 

 will flower a little late in the summer, and will be 

 good plants the following year. The - fern-lik$
