RHUBARB, or Pie-plant, is commonly grown by division of the roots, and this is the only method by which a particular type can be increased. Propagation from seed, however, often proves satisfactory, and always interesting, as the seedlings vary greatly. The seed germinates easily, and if started early the plants become fairly large and strong the same season. Although the crop is so easily produced, and so certain and regular after a plantation has once been started, it is one of the most profitable of market-garden crops, even in small places and neighborhoods. A large number of home gardeners are still without it on their premises, although everybody seems to want Rhubarb pie as soon as spring opens, this plant giving the first available material in the year for pies.
