Did you know?
This Rhododendron is fairly hard to grow since it needs just the right amount of moisture, always moist but not too wet. It is usually pollinated by female bumblebees. It looked so different from other rhododendrons that it was at one time put in the genus Rhodora, hence the common name. Rhodora is also the name of the botanical journal published by the New England Botanical Club.

State Ranking Justification [-]
There are approximately eight known populations, and some of these have hundreds to thousands of stems. Many of these populations are within protected landscapes. Today there are few threats on these populations and the short/long term trends appear stable.
