Growth Stages

1

Establishment

6-12 months

Young plant with compact rosette of blue-green leaves; slow initial growth

Water moderately during first growing season to establish deep root system; protect from frost in zone 8; ensure excellent drainage

2

Vegetative Growth

2-4 years

Leaves elongate and multiply; plant gradually increases in width and height; rosette becomes denser

Minimal water once established; no fertilizer needed; remove dead or damaged leaves; stake if needed in windy areas

3

Maturation

Ongoing

Plant reaches full size with impressive spherical form; leaves can reach 3-4 feet long; visual impact increases significantly

Maintain well-draining soil; no pruning necessary except to remove dead leaves; mulch lightly with gravel

4

Flowering

Spring to early summer, 4-8 weeks

Tall flower spikes (up to 15 feet) emerge from center with small whitish or greenish flowers arranged along the stem

Flowering occurs on mature plants; allows pollinators to visit; flowers followed by seed development

5

Seed Production

2-3 months after flowering

Flower spike develops seeds; spike gradually dries and becomes brown; seeds disperse naturally

Leave seed spike for wildlife benefit or cut back after flowering if dense growth is desired; self-seeds in ideal conditions
