Growth Stages

1

Spring emergence

3-4 weeks

New shoots emerge from the crown as temperatures warm. Low, compact growth with emerging foliage.

Cut back old growth to 4-6 inches if not done in fall. Apply balanced fertilizer. Ensure good drainage to prevent crown rot.

2

Vegetative growth

6-8 weeks

Rapid leafy growth creating a full, bushy mound of deep green foliage. Plant reaches 24-36 inches tall and wide.

Pinch back stem tips in early summer (before July 4) to encourage bushier, more compact growth with more flower buds. Water consistently. Divide crowded clumps every 2-3 years.

3

Bud formation

4-6 weeks

Flower buds appear at stem tips in late summer. Dense clusters of small green buds develop as days shorten.

Reduce nitrogen to encourage flowering over foliage. Ensure adequate air circulation to prevent powdery mildew. Stake or support tall stems if needed.

4

Flowering

6-8 weeks

Abundant double lavender-blue flowers (often 1-1.5 inches across) open in profusion from September through November. Blooms cover most of the foliage.

Deadhead spent flowers to extend blooming. Water deeply during dry periods. Monitor for aphids and spider mites. Enjoy for cutting; flowers last well in vases.

5

Dormancy

3-4 months

Stems gradually brown and foliage dies back after frost. The plant enters winter rest with dried stems above ground.

Cut stems back to 4-6 inches in late fall or early spring after hard freeze. Do not cut back too early in fall. Ensure drainage is excellent to prevent winter rot.
