Tulip poplars, also known as yellow-poplars or tulip trees (Liriodendron tulipifera), are deciduous members of the magnolia family known for their unusual, tulip-like flowers. These flowers appear in showy shades of cream, green, and orange. Tulip poplars can grow rapidly and reach heights of up to 90 feet (27 meters) with a spread of 50 feet (15 meters).

Flowering Period
Tulip poplars typically produce their first flowers at 15 to 20 years of age. Flowering occurs from April to June, depending on the location and weather conditions. Tulip trees that are a few decades old will usually flower reliably every year and can continue flowering for several hundred years.
Reasons for Not Flowering
If a tulip tree doesn’t flower, it may simply not be old enough. Tulip trees do not typically flower until they are at least 15 years old. Additionally, an unusually cold winter can cause many flowering trees to go without blooms in spring. In such cases, flowering may resume the following year.
Conclusion
The flowering of tulip poplars is influenced by age and environmental factors. Tulip trees typically begin flowering at 15 to 20 years of age and continue flowering for several hundred years. If a tulip tree is not flowering, it may be due to its age or unfavorable weather conditions.
