weeds, is to pull out the flower stalks when they appear. 



Helleborus atrorubens, H. caucasicus, H. Olympicus, 

 and other varieties. These plants are commonly known as 

 Lent Roses, and always succeed best if left in the same 

 position from year to year, but to get them true to name they 

 must be increased by division of the roots as soon as flower- 

 ing is over ; the pieces should be pulled asunder without 

 cutting, using a small handfork if the stocks are very large ; 

 they may then be planted out one foot apart each way, on 

 some good ground, and will require watering and mulching 

 if the weather is hot and dry afterwards. In two or three 

 years they may be moved to their permanent quarters. 



/ris foetidissima variegata. This is easily increased by 

 division, and the pieces after being planted on a piece of good 

 ground will make plants fit for use the following season. 



Iris pallida variegata. This is a far more beautiful plant 

 than the preceding, both for its foliage and flowers, 

 unfortunately it is not so robust in its growth, and takes two 

 years' longer to make good plants after division ; like all others 

 of this family it dislikes being moved after it gets established. 



CLASS II. 



The plants in this class are more easily increased, 

 and are not so particular as to time of division. 



Arabis albida, single white. This is very easily propa- 

 gated ; if pieces with a growing point are put in almost 

 everyone will make a large plant by the following October, 

 in fact they are often too large for single lines, and for that 

 purpose it is best to put in some more pieces early in June.
