Establishment
First yearYoung plant with small rosette of blue-green leaves, typically 6-12 inches across
Keep soil consistently moist. Mulch around the base to retain moisture and regulate soil temperature. Avoid transplanting for the first year.
Vegetative Growth
Years 2-3Leaf mound expands significantly; foliage becomes increasingly textured and deeply ridged; plant reaches 12-18 inches tall
Continue regular watering. Remove any flower scapes if you want to encourage leaf development. Fertilize in spring with balanced fertilizer. Monitor for slugs.
Flowering
4-6 weeks in summerTall scapes emerge from the leaf mound in early to mid-summer, bearing light lavender flowers in a dense raceme
Flowers are a bonus feature; deadhead if desired to redirect energy to foliage. The scapes do not detract from the plant if left to mature.
Maturity
Years 4+ (indefinite)Plant reaches full size of 24+ inches tall and 48 inches wide with massive, deeply textured blue-green leaves forming an impressive mound
Maintain consistent moisture and mulch. Annual spring fertilizer application supports continued vigor. Divide in spring if needed after 5+ years.
Dormancy
Fall to early springFoliage yellows and dies back to ground level in fall after frost
Leave dried foliage in place to protect crown from frost and provide winter interest. Cut back to ground level in early spring before new growth emerges.
