Other than a reader offering you some why not just buy a large plant when they become available and use it as a 'Mother plant', a source for many cuttings. They are one of the easiest to promote in this fashion.

Joe, to buy cuttings you need to order a minimum of 1500 at a time. I don't know anyone who sells just a few unless you have a grower nearby who would let you cut some. Geraniums always need to be trimmed this time of the year you might do some grower a favor. I keep 700 stock plants and take cutting all winter until April. Do what Jeannie says and get some mother plants... Bob.
