R. augustiniiR. augustinii is a rhododendron species that boasts variations of blue, purple, violet and lavender blossoms and can be available in a number of forms. We love the new foliage colors and textures, which change over time. R. augustinii can grow to over 6' tall at maturity and is hardy to 5F when protected from windchill. Plant in partial shade to full sun and anticipate blooms around April.
