Crater Lake


This incredible upright rhododendron with its clusters of ruffle-edged blue flowers make an immediate statement in any garden. While the blue trusses make this plant stand out, the hints of lavender add a dazzling color complexity. We love Crater Lake, both the park and the plant! Anticipate booming around April and grow in partial shade to full sun. It can grow to 5' tall and is hardy to -5°F when protected against windchill.
