Coldframes for Wintering Plants 201 



February will hr'.ng the flowers out again, and they will continue to 

 bloom until April. In summer all plants should be frequently sprayed 

 to keep them free from the red spider and green fly, otherwise they will 

 give trouble in winter. 



The best single blue varieties are California and Princess of Wales ; the 

 latter has the larger flower and longer stem. Among double blues, Marie 

 Louise and Farquhar dark are favourites, but Lady Hume Campbell or 

 light Farquhar is the best. This variety has a more rugged constitution, 

 and blooms later. 



Forget-me-nots are raised to perfection in coldframes. Sow the seed 

 in July in a sheltered spot in the open ground. In four weeks, or when 

 plants are large enough to handle, transplant three inches apart ; water and 

 grow along till late m September, then plant seven inches apart in 

 frames, and keep them growing till frosts set in. A covering of three inches 

 of dry leaves or straw should then be put over them. The frost will not 

 hurt them, but the sun shining on them when frozen burns the leaves. When 

 the weather gets warm in spring, remove the leaf mulch. The plants 

 bloom during April and May. 



With the same general treatment, but leaving them in the open, the 

 plants start to flower toward the end of May, and bloom continuously 

 till July. The seed then falls, in due time germinates, and flowers appear 

 next season. Old plants will bloom several years, but young plants each 

 season give best results. 



Wallflowers in coldframes are very satisfactory. Sow the seed in 

 April or May in the open ground or in "flats." When the seedlings are 

 large enough to handle, transplant three inches apart. They w411 crowd 

 each other in four weeks, when they may again be transplanted, giving 

 each plant a square foot. By the first of October they will be twelve inches 

 high, and bushy, and may be planted singly into six- or seven-inch pots, or 

 several in boxes, and removed to the frame, where they should be covered 

 to prevent alternate freezing and thawing. They do not like high temperature, 

 so the sash should be removed on all clear days, especially in February and 

 March, as they start growing then. They flower in April. We have heard 

 that around New Rochelle, N. Y., some plants have been known to flower 

 after being left outside all winter, but we have ne»^ei seen them. 



Mignonette is always welcome and a general favourite in the garden 

 and yard, but it is seldom seen in the window garden or coldframes,
