✂️ Maintenance
Light pruning in spring encourages a compact shape and denser flowering. Regularly remove spent flowers to extend the blooming period until the first frosts.
Water moderately during the growing season; this sage tolerates drought well once established. Well-drained soil is essential to prevent root rot. A light mulch helps retain moisture in dry periods.
Ideal for borders, sunny beds, butterfly gardens, and natural landscapes, this vigorous sage offers abundant and prolonged flowering while being low-maintenance and undemanding.
