Populus × acuminata ( anglais )

fourni par wikipedia EN

Populus × acuminata or Populus acuminata, the lanceleaf cottonwood, is a species of Populus native to the Rocky Mountains of North America. It is a naturally occurring hybrid of narrowleaf cottonwood, Populus angustifolia, and eastern cottonwood, Populus deltoides, found where their ranges overlap. It is planted as a shade tree in cities in the Rockies, preferring to grow at elevations between 4,500 and 8,500 ft.[3][4] Given the plant's proclivity (like other poplars) to send out shallow roots and suckers, some municipalities prohibit their planting. Fort Collins, Colorado, by contrast, has many lanceleaf cottonwoods gracing its avenues.[5]

Populus ×acuminata ( néerlandais ; flamand )

fourni par wikipedia NL

Populus ×acuminata is een hybride populierensoort uit de wilgenfamilie (Salicaceae).[1] Het betreft een kruising tussen Populus angustifolia en Populus deltoides. De soortnaam acuminata verwijst naar de puntige bladeren. Aan de bladvorm dankt deze kruising ook haar Engelse naam Lanceleaf Cottonwood.

P. ×acuminata is een snelgroeiende loofboom met een dichte piramidale groeiwijze. De bladeren zijn donkergroen aan de bovenzijde en lichtgrijs op de onderzijde, elliptisch met een scherpe punt en zacht sinuaire marges, tot 8 cm lang en 6 cm breed. De bladeren worden in de herfst geel voordat ze vallen. De schors is grijs / bruin en schilferig. De bloemen zijn tweehuizig en worden door de wind bestoven en verschijnen in de vorm van katjes. Na bevruchting vormt de boom groene doosvruchten.

P. ×acuminata komt van nature voor in de Rocky Mountains in Noord-Amerika. In zijn natuurlijke leefgebied groeit het in oevers en stromingsvlakten van rivieren. Hier geeft het de voorkeur aan vochtige, vruchtbare, goed doorlatende bodems. P. ×acuminata verdraagt een brede range aan pH van de grond, maar houdt niet van droge bodems. De boom kan zich verspreiden door worteluitlopers.[2]
