Dormancy
12-16 weeksBulb is planted in fall and remains underground through winter, requiring a period of cold (12-16 weeks below 55°F) for proper flowering.
Plant in October-November in northern zones, November-December in southern zones. Ensure excellent drainage to prevent rot. Mulch lightly if winters are very harsh.
Emergence
2-3 weeksShoots begin to emerge from soil in early spring as temperatures warm. Green shoots and foliage become visible above ground.
Remove any winter mulch once shoots emerge. Water if spring is dry. Monitor for slugs and snails which feed on emerging foliage.
Vegetative Growth
3-4 weeksFoliage develops fully; plant sends up a single sturdy stem with blue-green leaves. The flower bud forms inside the stem.
Provide consistent moisture as the plant grows rapidly. Apply balanced fertilizer once or twice during this period. Stake or support tall stems if needed in windy locations.
Blooming
7-14 daysLarge, elegant white flowers emerge in late spring. The blooms have a graceful form with slightly reflexed petals and yellow stamens, lasting 1-2 weeks when open.
Provide bright light to encourage full opening. Deadhead spent flowers but leave stems intact. Cut stems for vases when blooms first open; they will continue developing in water.
Post-Bloom & Dormancy
6-8 weeksFlowers fade and petals drop. Foliage yellows and dies back naturally as the plant stores energy back into the bulb for next year.
Do NOT cut off foliage until it is completely yellow and dry (at least 6 weeks after flowering). Continue watering until foliage dies back. Remove dead leaves and allow bulbs to dry.

Fun Facts
- 🌱 White Triumphator is a Darwin Hybrid tulip, a cross between the Darwin tulip and the Tulipa fosteriana species, resulting in exceptionally vigorous plants that often perennialize (bloom year after year) without lifting.
- 🌱 The name 'Triumphator' reflects this cultivar's victory in tulip breeding—it was developed to be a reliable, elegant late-season bloomer that resists disease better than many heirloom tulips.
- 🌱 White Triumphator flowers exhibit a fascinating response called heliotropism: on sunny days the blooms open wide and may slightly close at night or in cool temperatures, giving dynamic beauty throughout the day.
