Poplar (white)
General characteristics of a Poplar (white)
The white poplar (Populus alba), also known as the silver poplar, is a tree in the willow family (Salicaceae). The plant is native to Central and Southern Europe and Central and Western Asia. It has been present in the Netherlands since the 17th century. The tree is a fast grower that requires ample space and is prone to broken branches.
The tree is easily recognized by its bark and leaves. The bark is white-gray with characteristic black diamond-shaped markings. As it matures, the bark on the underside of the trunk turns black. The leaves of this white poplar are green on top and white and felty on the underside.
The white poplar is dioecious, meaning that there are trees with only male flowers and trees with only female flowers. It flowers in March and April, before the leaves emerge. Female drooping catkins are yellow. The male ones are red. After the pollen has blown away, they fall off. The female ones remain on the tree for a longer period. Then the seed pods open, releasing the seeds surrounded by downy fluff.
Characteristics
How to plant a Poplar (white)
The white poplar is usually supplied as self-rooting "slits" of 1-3 m in length. Plant them as deep as possible, 40-60 cm into the soil, preferably until the soil is moist, ideally from mid-February to the end of March. There is less chance of them taking root in November or December. Transplanting rootstock is also possible.
How to harvest a Poplar (white)
There are two ways to harvest white poplar. Gather rootstock around mature trees or prune branches for shoots.
Caring for and pruning your Poplar (white)
Like other poplars, the grey poplar often suffers from broken branches later in life. Removing overloaded branches in time can help prevent this to some extent.
Where does a Poplar (white) grow
(Dune) sand because of its good resistance to sea air. The tree is often planted as an avenue tree and along roads. You can also regularly find the white poplar in parks. In the wild, the tree grows on dune edges and the edges of river valleys.

Reproduction rate
| 1. Very low reproduction rate. The plant hardly spreads, has few seeds or vegetative spread (e.g., trees with heavy seeds). |
| 2. Low reproduction rate. Spread via limited seed production or specific conditions required |
| 3. Average reproduction rate. Regular spread, depending on wind, water, or animals, at a moderate speed (e.g., dandelion). |
| 4. High reproduction rate. Many seeds and multiple spread strategies (wind, birds, vegetative). Quickly colonizes open spaces |
| 5. Very high reproduction rate. Invasive species that spread explosively over large distances (e.g., Japanese knotweed). |

Harvest/recognition in winter
The white poplar produces a lot of rootstock. A mature tree has diamond-shaped lenticels in the bark. The buds are usually light brown to reddish-brown, elongated and pointed with white woolly hairs, and are arranged alternately on the branches.
