Juvenile Growth
1-2 yearsPlant develops multiple fan-shaped fronds with characteristic serrated petioles (leaf stems). Gradually increases in height and girth.
Reduce watering frequency as drought tolerance increases; minimal fertilization needed; remove dead fronds; maintain mulch layer
Maturation
1+ yearPlant reaches full structural form with dense crown of blue-green fan fronds. Growth slows; plant becomes increasingly drought-tolerant.
Water only during severe droughts; apply light fertilizer in spring if growth seems slow; prune only dead or damaged fronds
Flowering
4-8 weeksSmall, cream to yellow-white flowers emerge on branched inflorescences in late spring to early summer, nestled among the fronds.
No special care needed; flowers are inconspicuous but attract pollinators; ensure adequate light for optimal flowering
Fruiting & Harvest
3-4 monthsFlowers develop into dark blue-black, olive-sized drupes (berries) by late summer through fall. Berries persist on plant for extended periods.
Harvest berries when fully dark (blue-black) in late August through October; wear gloves for collection; allow some berries to remain for wildlife
