What’s in Bloom


The Arboretum’s diverse living collection set amidst a quintessential Vineyard landscape offers beauty and interest to visitors on every day of the year. Even in the depths of Winter gorgeous bark, showy fruits and even some flowers provide beauty and interest for those who venture out to explore.  Once Spring arrives the Arboretum offers an ever-changing procession of bloom that extends well into Fall.  This regularly updated list highlights what plants are currently in bloom or are significant for a showy display of fruit, foliage, bark, or other interesting features.
