and should be given a sunny yet sheltered place, with 

 a sandy loamy soil. A stock may be raised by sowing 

 seed under glass in spring, wintering the plants thus 

 raised in a cold frame, and planting out in spring. When 

 established they may be increased by division in spring. 



LIN ARIA (Toadflax). — ^The Linarias are a rather 

 large genus, and they comprise some very pretty and 

 useful plants, both annual and perennial. The dwarf er 

 perennial species should be made good use of by those 

 who have to plant dry rockeries, for they are as accom- 

 modating as Sun Roses. They will thrive in ordinary 

 garden soil, and do not mind poor chalky ground. 

 A stock of plants can be raised by sowing seeds in fine 

 prepared soil out of doors at mid-spring. Afterwards 

 farther propagation may be effected by division in 

 spring. Alpina (see coloured plate) is a charming 

 species. It comes from the European Alps, and bears 

 violet flowers marked with orange, in summer. It is 

 generally biennial, but by sowing itself serves the 

 purpose of a true perennial. There is a variety of it, 

 differing in colour, called rosea. Cymbalaria, known as 

 the Kenilworth Ivy, is a pretty trailer with lilac 

 flowers, and will grow on old walls. There is a pink 

 variety called rosea y and a white called alba. Another 

 useful species is hepaticaefolia (Hepatica-leaved), a 

 trailer with purple flowers. 



LINNMA BOREALIS,—A pretty evergreen 

 trailer, about four inches high, with perfumed pink 

 flowers which it bears in June. It Hkes a cool place 

 and a moist peaty soil. Propagation may be effected 

 by division.
