And the List of Blooming Plants Grows (Updated May 18) - Arboretum gardening and horticultural staff found about twice as many blooming plants on the grounds this week as they did last. The big news is that the Northern Lights Azaleas are blooming in many locations on the Arboretum grounds in a variety of intense colors. The lilacs are putting on a spectacular show as well.
