Paulownia tomentosa price

Paulownia tomentosa is a plant that is used for several purposes. If you want to buy it only for ornamental purposes, you should know that its price varies according to the age and size of the plant. It therefore ranges from 18 euros for a specimen with a trunk circumference of 8-10 centimeters, to 135 euros for an adult specimen of about 20-25 centimeters in circumference. If the aim is to create a plantation to then use the paulownia wood then there are different solutions: some companies sell the individual plants in a jar with virgin peat substrate, ready for planting, at 4 euros each; alternatively, you can buy a package, i.e. a certain amount of seedlings in stock, depending on the size of the land you have available, paying less because you buy in large numbers. Some companies, for example, sell 600 plants for 2400 euros. In other farms, however, the price is per hectare and is between 3000 and 5000 euros per hectare, depending on the characteristics of the land, such as shape, relief, composition and irrigation system.

Paulownia tomentosa is a tree that is part of the Scrofulariaceae family. Originally from China, it reaches up to twenty meters in height: it has a wide and horizontally developed crown, with the trunk often inclined. The bark is light gray-brown and rough; the deciduous leaves are large, with acute apex, covered with down, and of an intense green. The leaf reaches up to 30 centimeters in length and has an oval shape, or is divided into three lobes. The flowers are very beautiful: tubular and hermaphrodite, they are born between April and June, before the leaves, have an intense scent and are among the favorites of bees. They are usually violet, or white with bluish hues, about 6 cm long and gathered in clusters about 25 cm long. The fruits are hard capsules of about 40 mm, covered with fluff: in autumn they become dark and then open, letting the many seeds fall which are then dispersed with the wind. The production of large quantities of seeds begins around 8-10 years of age of the plant. The roots don’t go very deep, unless they experience a long period of dryness.

Paulownia tomentosa cultivation

The paulownia tomentosa prefers sunny places, but can grow well even in partial shade; it resists well both winter frost and summer heat. It usually develops better if it is planted as a single specimen. Young plants need to be watered sporadically in hot periods of the year, while rainwater is sufficient for adult specimens. In any case, it is always better to place a mature organic fertilizer at the base of the plant in spring, and then fertilize with slow release fertilizer at least once a year. The paulownia adapts well to any soil, as long as it is well drained and, in fact, rich in organic substance, which favors its rapid growth in the first three years of life; the large seeds released by the fruits in spring can be sown immediately. Newly born seedlings can be immediately planted and in spring they can be removed by root or branch cuttings. Paulownia has a weakness: it is often attacked by fungi such as Phyllosticta paulowniae, Phyllactinia guttata, and Uncinula clintonii. Of these three, only the guttata species is present in Italy.

Paulownia tomentosa uses

Introduced in Europe in 1700 as an ornamental plant, paulownia tomentosa is still used today for this purpose, both as a single plant and in groups in gardens. It is also used as a windbreak thanks to its thick foliage, or as a barrier against dust pollution, which the plant manages to retain thanks to the hair on the leaves. But this tree is also used for two other purposes: wood and biomass. Paulownia wood is precious, resistant, flexible and light: in the East it is used for musical instruments, for geta, that is Japanese sandals, for cabinets and masks. In the West, however, it is used to make coatings, objects and furniture. It is not attacked by woodworms, resists humidity and works very well; the only problem is that it doesn’t hold screws and nails, so you have to use glue. The paulownia is therefore grown in plantations to use wood but also to produce biomass, an energy source of organic origin and which therefore respects the environment. Finally, its leaves can be used to fertilize land or as forage for livestock, given their high protein content.
