Propagation of challenging plants: creating a system that works©

J. Johnson
There are certain things to look for when reviewing plant propagation literature. Start by looking at the history of specific plant type propagation or propagation of related plants. Determine up front if the information is anecdotal (someone’s observation), repeated observations by someone who is familiar with the plant in question, or a scientific study. Each type has some value as a starting point but as one moves toward a more scientific study, the value increases.
This work was initiated by two request. In tissue culture (TC), Cornus kousa ‘Rutpink’, Scarlet Fire® kousa dogwood multiplies well and produces great shoots. Unfortunately, procedures have not resulted in roots initiating. Vaccinium macrocarpon ‘Haines’ produces good shoots and roots in TC but first generation cuttings taken commercially from the rooted TC plants rooted very poorly. Additional plants noted in this paper were assessed in the system propagation developed because they were of personal interest.
