134 STUDIES IN GARDENING 



Well-grown plants are 4 or 5 ft. liigh and bear a 

 dozen or more flowers. It likes a good loamy soil 

 mixed with leaf-mould, but is said to thrive in stiff 

 clay if well drained. It suffers from drought if ex- 

 posed to the full heat of the sun, and should be grown 

 among low shrubs or herbaceous plants. It will sel- 

 dom thrive on a bare patch of ground. It is best 

 planted in early autumn and takes some years to reach 

 its full beauty; so it should not be disturbed when 

 once well established. It grows very well in the grass 

 in half shade at Wisley, and can be raised from seed, 

 though this is a slow process. It is often called also 

 L. monadelphima, but this is really a distinct species 

 with flowers of a darker yellow. 



Three North American hlies — L. Canadense, L. 

 pardalinum, and L. superbum — grow well and in- 

 crease in a moist soil rich in humus, if they are 

 protected both from cold winds and from the full 

 heat of the sun. They like peat well enough, but 

 prefer it enriched with loam and humus. L. par- 

 dalinum and L. superbum will grow also in fairly 

 dry shady places if they are well watered in dry weather. 

 They do well among shrubs, such as azaleas, rhododen- 

 drons, kalmias, &c., but they must not be smothered 

 by them. When the soil is not naturally moist it is 

 well to plant them in a slight hollow where the water 

 will be collected and drain down to their roots. Their 

 chief enemy is drought, and they will not usually 

 thrive in the ordinary border. They should not be 

 disturbed when established, and if grown in a suit-
