Growth Stages

1

Propagation & Establishment

4-8 weeks

Soft to semi-hardwood cuttings develop roots; young plants establish shallow root systems.

Use well-draining propagation mix; maintain consistent moisture without waterlogging. Apply hormone rooting powder to cuttings. Provide bright, indirect light until rooted.

2

Vegetative Growth

8-12 weeks

Foliage expands; fine, needle-like leaves develop in whorls along stems; plant forms mounding shape.

Water moderately; pinch back growth to encourage bushiness and branching. Provide full sun. Fertilize lightly every 4-6 weeks with balanced, low-nitrogen formula.

3

Flowering

12-16 weeks (spring through fall in warm zones)

Delicate lavender-blue, tubular flowers appear in leaf axils and along stems; blooms occur in cycles throughout warm months.

Maintain consistent but moderate watering during flowering. Deadhead spent flowers to encourage continued blooming. Avoid overfertilizing, which reduces flowers.

4

Maturity & Dormancy

Ongoing seasonal cycle

Plant reaches full ornamental size and form; flowering slows in cooler months or winter. Growth slows significantly.

Reduce watering in winter; allow plant to dry between waterings. Minimal fertilizer needed. Prune lightly in late winter to maintain shape if desired.
