Most of the here presented plants cannot be bought in European nurseries at the moment, though more and more are becoming available. If they are offered, then often there are just a few clones, which does not cope with the high variability that can be found in nature. Another problem is, that sometimes the sold plants do not agree with their labels.
The best and easiest way to get good plant material, often even with field data, is the seed distribution of the Deutsche Rhododendrongesellschaft (DRG). To benefit from this a membersip in DRG is necessary wich is well worth it for several reasons. At the moment there is a wide selection of species available. With the kind help of my American friends I try to make sure, that this goes on in the future.
I do not have a nursery and therefore I cannot sell plants in noteworthy numbers. Surplus seedlings I often donate with the help of DRG to a few intersted botanical gardens. So in the future more and more American rhododendrons will be seen in these gardens. Occasionally I can give a few plants to DRG members or bring them along to our meetings.
