Dormancy & Root Development
8-12 weeksBulb is planted in fall and develops roots over 8-12 weeks in cold soil without visible above-ground growth.
Plant in October-November in well-draining soil. Ensure bulbs contact soil. Mulch lightly to insulate. Keep cool and moist over winter.
Emergence & Foliage
2-3 weeksIn early spring, mottled gray-green leaves emerge from the soil, characteristic of Greigii varieties, followed by flower buds.
Remove mulch as growth begins. Monitor for slugs and snails. Provide occasional water if rainfall is scarce. No fertilizing needed at this stage.
Bud Formation
1-2 weeksThe flower bud develops and elongates, still enclosed in the emerging stem. The plant reaches near full height.
Protect from strong winds with stakes if needed. Apply diluted liquid fertilizer to support bloom. Ensure consistent moisture.
Blooming
2-3 weeksCup-shaped flowers open, displaying vibrant red-orange petals with striking yellow base. Flowers face upward and may open/close with temperature changes.
Deadhead spent flowers to extend bloom period. Protect from heavy rain and strong winds. Do not remove foliage yet. Avoid overhead watering.
Senescence & Bulb Restoration
4-6 weeksFlowers fade and petals drop. Foliage remains green and continues photosynthesis to rebuild bulb energy reserves.
Let foliage die back naturally (4-6 weeks after bloom). Continue watering and apply low-nitrogen fertilizer (bulb booster). Do not cut leaves early or bulb won't return next year.

Herbal Infusions
CulinaryTulip petals can be steeped to create delicate herbal teas with subtle floral notes, though this is less common than culinary use of the fresh petals. [source]
Harvest Tips
Cut tulips for arrangements in early morning when stems are turgid. Slice stems at a 45-degree angle. Remove lower leaves and place in fresh, cool water. Change water every 2-3 days. For garden display, leave flowers on plant and deadhead only spent blooms to allow foliage to feed the bulb. Do not cut foliage until it yellows (typically 4-6 weeks after bloom).
Fun Facts
- 🌱 Greigii tulips are named after Carl Friedrich von Greigius, a 19th-century Russian botanist and plant collector. They are known for their distinctively mottled or striped foliage, which sets them apart from other tulip classes.
- 🌱 Toronto tulips are part of the Darwin Hybrid group's heritage and were bred to have exceptional disease resistance and reliable perennial return, making them more reliable than many other tulip varieties in the same hardiness zone.
- 🌱 Tulips have a unique characteristic called nyctinasty—they open and close their petals in response to temperature changes, opening wide on warm days and closing tightly at night or in cold weather.
