The term 'purplish bloom' can refer to three different flowers: the LILAC, ASTER, and dayflower. The LILAC is a fragrant shrub with clusters of purple flowers that bloom in the spring. The ASTER is a perennial flower with daisy-like blooms that come in shades of purple. The dayflower is an annual flower with small, star-shaped blooms that range from blue to purple in color. All three of these flowers have purplish blooms and are popular garden plants.
