Growth Stages

1

Seedling

2-3 weeks

Small leaves emerge from soil; plant develops low rosette of narrow, lance-shaped foliage

Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing.

2

Vegetative Growth

4-6 weeks

Plant develops deeper root system and larger rosette of hairy, textured gray-green leaves; stems begin to elongate

Reduce watering frequency as plant establishes. No fertilizer needed if soil is decent. Remove any weak stems.

3

Flowering

4-8 weeks (late May through July)

Tall flower spikes (18-24 inches) emerge with densely packed deep purple-violet tubular flowers arranged in whorls

Deadhead spent flowers to encourage more blooms throughout late spring and early summer. Stake tall stems if needed in windy locations.

4

Post-Flowering

8-12 weeks (August-October)

Flowers fade to seed heads; foliage remains attractive and gray-green; plant hardens off for winter dormancy

Cut back spent flower stems by half. Leave some seed heads for wildlife and winter interest if desired. Allow plant to rest.

5

Winter Dormancy & Spring Renewal

4-6 months dormancy; regrowth in spring

Foliage dies back in cold climates; plant goes dormant underground. In spring, new shoots emerge from crown

In very cold zones, mulch lightly after ground freezes. Cut back any dead growth in early spring. No supplemental water needed.
