After a forced two year hiatus Books in Bloom is back, offering a preview of colorful things to come. What is Books in Bloom? Sponsored by the New Friends of the Saugus Public Library and Saugus Garden Club, it is an annual event where local flower enthusiasts put together floral arrangements that interpret a book’s title, book jacket, or theme. Each arrangement contains some fresh plant material (foliage, flowers etc.) and, of course, a book. Showings take place around the library on Friday, May 20th (9:00 a.m. to 4:30 p.m.) and Saturday, May 21st (9 a.m. to 3:00 p.m.).
