General characteristics of a Russian Olive. Caution - invasive!
Willow (Narrow-leaved olive)
The narrow-leaved Olive Willow is a medium sized tree or large shrub that can grow to a hight of 6 to 10 meters. Its characteristic features are its elongated, narrow leaves, which have a grayish-green upper surface and a silvery sheen on the underside.From late spring until early summer the tree produces small fragrant yellow flowers that grow in clusters that attrackt bees and butterflies.
The fruits are olive -like and edible. This species is highly tolerant of drought and high temperatures. Furthermore, the narrow olive willow is tolerant of air pollution, making it a popular choice for urban areas. Despite its benefits, it can become invasive in some regions, potentially displacing native plants.

Where does a Russian Olive. Caution - invasive! grow
Narrow olive willow grows in very sandy, often more or less disturbed, moderately to highly nutrient-rich, and rather dry habitats. The species is generally found primarily in dunes and on reclaimed land. To a lesser extent, it can appear on abandoned railway lines and industrial estates. It can grow in both wet and dry areas.
Smalle olijfwilg groeit op uitgesproken zandige, vaak min of meer verstoorde, matig tot sterk voedselrijke, eerder droge standplaatsen. ln het algemeen wordt de soort vooral aangetroffen in duinen en op opgespoten terreinen. In mindere mate kan ze opduiken op verlaten spoorwegen industrieterreinen. Hij kan zowel in natte als droge gebieden groeien.

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). |
