From the ARS announcement:

Wondering what we’ve been up to since 1992, when this event was last staged on Long Island? District 7 hybridizers have made exciting progress on the challenge of creating a host of new rhododendron cultivars for the Northeast, that extend the range of flower color, cold hardiness and overall performance. Join us for a celebration of these accomplishments at the upcoming ARS Convention to be held on Long Island.
