|I. sempervirens is a very attractive, spreading evergreen with narrow, dark green leaves. When in bloom, this plant is covered with clusters of pure white flowers and usually max-out by June. It is not uncommon for sporadic flowering to continue throughout the year. Some selections such as 'Snowflake' is a repeat bloomer, doing so sporadically throughout the year. Excellent for rock gardens and borders, this plant flowers best when it recieves morning sun.
