Pollarded trees do not produce flowers, as these form only on mature wood. Paulownia tomentosa requires full sun for proper growth.

A deciduous angiosperm, Ochroma pyramidale can grow up to 30 m tall, and is classified as a hardwood despite the wood itself being very soft; it is the softest commercial hardwood and is widely used because of its light weight. Balsa trees grow extremely fast, often up to 27 metres in 10–15 years, and do not usually live beyond 30 to 40 years.
This species is also fast-growing, without the common problems of weak wood strength and short lifespan often seen in fast-growing species. In 2024 the unusual combination of fast-growing with strong wood was explained. No longer called a hardwood, the term "midwood" was created expressly for the wood of tulip tree. [5]
