They are known to grow up to 15 feet (4.6 m) or more in the first year. It is reportedly the fastest-growing hardwood tree [citation needed]. Some proponents state that P. elongata plantations can reach a harvestable size in five to seven years. [citation needed].
Pollarded trees do not produce flowers, as these form only on mature wood. Paulownia tomentosa requires full sun for proper growth. [15] [16] It is tolerant of pollution and can tolerate many soil types. It can also grow from small cracks in pavements and walls. Paulownia can survive wildfires because the roots can regenerate new, very fast ...
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.
SRF is the practice of cultivating fast-growing trees that reach their economically optimum size between 8 and 20 years old. Species used are selected on this basis and include alder, ash, southern beech, birch, Eucalyptus, poplar, willow, [1] [2] new varieties of Paulownia elongata, paper mulberry, Australian blackwood and sycamore.
