✂️ Care

Pinch back stems in early summer to encourage dense branching and more generous flowering. After autumn blooming, cut the plant back to 10-15 cm from the ground to prepare for winter. Apply an organic mulch at the base to protect the roots and enrich the soil.

Divide clumps every 3 to 4 years in spring to maintain vigor and rejuvenate the plant. Water regularly the first year to establish a robust root system. Once well-rooted, the plant tolerates dry periods well and requires little maintenance. Stake if necessary to support tall stems late in the season.
