| Portland Chapter Home | Smith Home | Visitations | Rhododendrons |
This is a partial list of the rhododendrons in the garden. These are the rhododendrons about which we have reasonable confidence in their provenance. In order to avoid a long entry, R.degronianum ssp. yakushimanum var. yakushimanum is entered simply as yakushimanum. 'Koichiro Wada' is a named form of R.degronianum ssp. yakushimanum var. yakushimanum.
Some of the entries reflect plants that were not found on the latest garden survey. It is possible that
they were missed in the inventory, so are still carried in this list. These usually don't have a 'bed'
number in their entry.
Identical multiple entries may reflect multiple plants or only
multiple entries in the database.
This list is available in zipped text form in plant name order or accession number order
