flowers in late spring or early summer, and grows a 

 foot high, the latter purple flowers. It grows about a 

 foot and a half high, and has downy leaves. If seed 

 can be procured, it may be sown in a frame in Spring, 

 and propagation may also be effected by division 

 between autumn and spring. Sandy loam, with a 

 little peat, suits them. 



CORYDALIS (Fumitory). — As already stated, 

 this genus contains members of great value owing to 

 their graceful foliage, bright flowers and freedom of 

 growth, but which are apt to become troublesome if left 

 unchecked. A notable instance is the yellow Fumitory 

 C. lutea. This is an undeniably pretty plant, with a 

 store of vitaUty which few plants can equal, but in 

 congenial places it becomes an undoubted weed. This 

 is particularly the case on limestone. It loves to 

 estabhsh itself among stones, whether in the rockery or 

 on walls. It wiU settle down comfortably in the mouth 

 of a drainpipe. The stems are thick and succulent, 

 able, apparently, to make their own moisture. I 

 allow it to grow under strict supervision, making 

 drastic reductions at frequent intervals. It sows 

 itself everywhere and needs more curbing than en- 

 couraging. It begins to bloom in spring, and goes on 

 spreading and flowering all the summer. C. nohilis is 

 a finer plant. It also has ferny foliage, and the yellow 

 flowers are marked with chocolate. It blooms in late 

 spring. It does not spread like lutea, and may have 

 a little cultural care, such as the provision of light loamy 

 soil and propagation by division. Cheilanthi folia and 

 thalictrifolia are also pretty, but the latter could only
