Although weather and other variables play their part, we can pretty much predict from year to year what will bloom and when. Here’s a partial list of plants you’re likely to find flowering at Coastal Maine Botanical Gardens at various times.

To search for what’s in bloom during a specific time period, please visit FloraFind. Details on new flowering plants are added throughout the season.

You can also visit our Image Galleries to see pictures of the Gardens in all seasons.
