 stocks as the fruit-bearing sorts. See Prunus.

Increased by bulbels. Remove these from the parent 

 bulb in the fall, and keep in a warm, dry place until the 

 following spring. The soil should be light, rich and 

 moist throughout the summer. Before frost comes in the 

 fall, take the bulbs up, and when dry, cut off the leaves. 

 The bulbs should be kept as during the preceding winter, 

 and the culture during the following year is the same as 

 during the first. The bulbs usually flower the second or 

 third summer.
