the begimiiug of August ; they do not come up till spring, and 

 when of a pretty good size, the young plants should be transplanted 

 into a shady bed there to remain until autumn, when you may 

 plant them where they are to remain. The double sort bears no 

 seed, therefore is propagated only by dividing the roots, which is 

 the easiest and, perhaps, best way of propagating either. Do this 

 as soon as the plant has done flowering, keep it moist till it have 

 taken root ; water, if the weather be very dry ; and do not part 

 the roots more than once in three years, as the tufts must be pretty 

 thick to flower well. — Violet, the dogs-tooth. — Lat. Erythronium 

 dens canis. A purple pendulous flower with leaves spotted with 

 brown on the upper side. Blows in the beginning of April. May 

 be transplanted any time between June and September. Roots 

 should not be kept out of the ground long, for they are apt to 

 rot. Plant in patches, ten or a dozen roots near to one another, 

 as they look best so. Perennial, four inches high. 



596. WALLFLOWER. — Lat. Cheiranthus cheiri. A biennial 

 plant of the south of Europe. Grows from one to two feet high, 

 and blows a fine yellow flower from April till June. Propagated 

 by seed, sowed in a hot-bed of moderate heat, or in beds out of 

 doors in March. When they are four or five inches high, they 

 are planted where they are to remain. They want little w^atering, 

 and a soil rather dry than moist. The double ones are pro- 

 pagated by cuttings planted in good earth and rather shaded. This 

 plant is called hardy, but in very severe frosts it should have pro- 

 tection, or it blows late and sparingly, and not so double as other- 

 wise it would. It may be made the hardier by being sowed in 

 poor ground, which causes the plant to be less succulent and con- 

 sequently less susceptible of frost. It grows well on old walls, or 

 any walls, indeed ; or on rubbish of any kind, and makes a pretty 

 show wherever it is found. 



597. WILLOW-HERB, ^^ero5e hay. — Lat. Epilohhim anyusti- 

 folium. A native perennial plant, owing its vulgar name to the 

 resemblance of its leaf to that of the common willow. It grows 

 three or four feet high, sends up innumerable branches, which are 

 decked thinly all the way up by narrow pointed leaves, and, to- 

 wards the tops of these branches, it bears a peach-blossom flower 

 in July and August. It is a troublesome thing i.i a flower border, 

 on account of the great quantity of stems that it sends up from its 

 very wide-spreading root, and, on this account (as well as on ac-
