Growth Stages

Establishment (Spring planting)

4-6 weeks

Young plant develops root system; foliage is compact and green

Water regularly to establish roots. Mulch around base with 2-3 inches of organic matter, keeping mulch away from stem. Avoid heavy fertilizing.

Vegetative Growth (Spring-Early Summer)

8-12 weeks

Stems elongate; foliage becomes denser and fuller; plant establishes its shape

Pinch back tips in early spring to promote bushiness. Light pruning to shape. Water moderately and consistently. Begin monthly balanced fertilizing.

Flowering Peak (Mid-Summer to Fall)

12-16 weeks

Dense spikes of lavender-purple flowers emerge from stem tips; plant is covered in blooms; foliage remains attractive

Deadhead spent flower spikes to encourage continuous blooming. Continue regular watering; do not allow soil to dry out. Feed monthly with balanced or low-nitrogen fertilizer.

Late Season/Dormancy (Late Fall-Winter)

12-16 weeks

Flowering diminishes; foliage may become bronzed or partially deciduous; plant prepares for rest

Reduce watering frequency as growth slows. Cease fertilizing. Prune lightly only if needed for shape; avoid heavy pruning. Protect from harsh freezes in zone 8b.
