Healthy larger rhododendrons will often produce more terminal flower buds than terminal leaf buds as the plant grows older. I don't usually suggest anyone get onto a ladder to deadhead, sometimes deadheading just isn't practical. Rhododendrons expend a great amount of energy setting seed in summer, energy that would otherwise go into flower bud production. Skipping deadheading can lead to heavier flowering every other year, more pronounced on some, and on younger rhododendrons - it isn't necessarily true of all of them or all ages of them. If you can safely reach and don't plan to collect the seed, there is no reason to let the seed form. Those persistent seed pods can distract from their appearance too when down more near eye level or lower, you'll have fresh blooms with remnants of the old still visible the following year.

Thanks for the tip--I've already checked them out. It seems like that will be my best bet. I've also joined the ASA. They have an annual seed/swap sale that may be a resource for me as well. Bruce

If you are still looking, here are people that share their seeds,and have a nice variety. Here is a link that might be useful: willow garden

ok then please email me about the trade thanks
