White or pale pink, extremely fragrant flowers grow in corymbs (clusters) of 5-20 and have five showy petals with the uppermost splashed with orange on the inside, signaling pollinators. Long stamens protrude out of the trumpet shaped throat. Fruit is a capsule occurring in clusters. Blooms May to June.

Growing Conditions: full sun to partial shade in well-drained, moist to wet acidic soil.  Rhododendron occidentale does not grow with its roots submerged in water and has no tolerance to drought.
