V. nigrum, the variations do not appear sufficiently constant to 

 warrant making separations. In general, the plant is of low, 

 semi-prostrate habit, is extremely prolific and thrives on dry 

 sandy hills. It furnishes the bulk of the blueberries found in the 

 eastern markets. When mown down or burned, the new erect 

 shoots produce, the following year, a long spike-like mass of 

 bloom and fruit which may be stripped off by handfuls. 

 Because of its character, and early ripening habit, it is known on 

 the blueberry plains as "early sweet" or "low sweet."
