Dormancy/Planting
3-4 monthsBulbs planted in fall go dormant underground. Minimal visible growth; roots develop over winter.
Plant bulbs October-November in well-draining soil. Ensure excellent drainage to prevent rot. Protect from excessive winter moisture with gravel mulch.
Sprouting
3-4 weeksNarrow green shoots emerge in late winter to early spring as temperatures warm. Single or multiple stems per bulb develop.
Reduce watering slightly as growth begins. Monitor for slugs and snails. Ensure good air circulation.
Vegetative Growth
4-6 weeksStems elongate with thin, grass-like foliage. Plants develop height (12-24 inches) with minimal leaf development.
Continue moderate watering. Support tall stems if needed with small stakes. Do not fertilize heavily.
Flowering
2-3 weeksCup-shaped flowers with 3 petals bloom at stem tips in late spring to early summer. Flowers feature intricate patterns with hairy glands and striking color combinations.
Water moderately but avoid wetting flowers. Protect from strong winds. Enjoy blooms; each flower lasts several days.
Post-Bloom Dormancy
4-6 weeks until complete dormancyFlowers fade and seed pods may develop. Foliage yellows and dies back naturally. Plant enters summer dormancy.
Cease watering as foliage dies back. Allow seed heads to mature if collecting seed. Do not disturb bulbs; leave undisturbed for future seasons.

Harvest Tips
Superb Mariposa is grown for ornamental flowers, not harvest. Enjoy blooms on the plant in situ. For seed collection, allow flowers to mature into seed pods in early summer, then harvest dried pods before natural splitting. Do not cut or remove bulbs unless absolutely necessary; allow them to naturalize and spread over years.
