Syringas (Lilac), which typically bloom in the spring, have been a landscapers' choice for years because they are easy to care for, have a hardy nature, have a long flowering period and shows off a bright color (purple or blue, and at times off-white). It also has an appealing and intoxicating fragrance, too! Many of these beautiful flowering shrubs can grow up to be as much as 30 feet tall!
