Meristem vs Scape Tissue in Tissue Culture Propagation

Hosta propagation by Tissue Culture (TC) growth can be accomplished using two different types of Hosta tissue: meristem and the young scape tissue. In general the meristem is the preferable of the two tissue types because it is the only way to produce variegated hostas from a variegated tissue donor. If the genetic traits for variegation are not required, the use of young scape tissue can be used to grwo solid color (green or blue) plants. To understand why it is necessary to become familiar with the genetics of hostas. (see chimeras) When using young scape tissue, make sure to use only the newly emerged and still actively growing crown centers.
