Zone 5b dates sourced from www.longfield-gardens.com.
Tulips are planted in fall and bloom the following spring, which means the payoff for this year's work doesn't show up until next year: one upright, cup-shaped bloom per 12- to 24-inch stem, in almost any color except true blue. Even then, most hybrid tulips put on their best show once and fade in vigor after that. Treating them as a bulb you might replant rather than a permanent perennial saves a lot of disappointment.
How tulip fits zone 5's season
Zone 5b's frost-free window runs about 148 days, from May 10 to October 5. Tulip needs about 180 days from sowing to first harvest.
