152 PRACTICAL FLOHICULTURE. 



white, by sowing seed in August and transplanting to 

 cold frames in October. We ourselves raise tens of thou- 

 sands in this way, as we have not suitable soil to keep the 

 established kinds, that are propagated by division, alive 

 through the hot summer. 



Cowslips, Primroses and Auriculas are beautiful spring 

 plants, when kept over as are Pansies in cold frames. 

 They are also increased by division, like the Daisy, but 

 the process is slow and they are often, like the Daisy, 

 difficult to keep through our hot and dry summers, but 

 they can all be easily raised from seed, which should be 

 sown about the same time in spring as we sow the Chin- 

 ese Primula. See Chapter 22 on Propagation by Seeds. 



Myosotis (Forget-Me-Nots), When wintered over in 

 cold frames, the Forget-me-nots bloom freely in early 

 spring. They can easily be kept over the summer by 

 planting in some cool, partially shaded place, and in- 

 creased by dividing in fall, or they may be grown from 

 seed, exactly as recommended for Cowslip or Primrose. 



In addition to the plants just named as being grown in 

 cold frames, to bloom in early spring, the following half 

 hardy plants that bloom later in the season can all best 

 be raised from seed and grown in cold frames during 

 winter : Aquilegia, Delphinium, Digitalis and Holly- 

 hocks. Although these are all hardy in this latitude, we 

 find that better plants can be had the first season from 

 seed by protecting them in cold frames. The distance 

 apart at which plants are set in cold frames must be gov- 

 erned by the size and kinds ; we ourselves plant from 100 

 to 200 in a three by six foot sash.
