Ailanthus altissima: "toxic tree of heaven"
"Des Higgins" wrote in message . ie... "Bill" wrote in message s.com... NB: this is posted to uk.environment.conservation and uk.rec.gardening "The toxic Tree of Heaven threatens England's green and pleasant land" http://observer.guardian.co.uk/uk_ne...874333,00.html '...grows raipidly to heights of 80ft or more...' '...amateur gardeners should be vigilant. Look out for sprouts and self sown seedlings... remove them.' '...Ailanthus leaks toxins into the ground which prevent the germination and establishment of other species in its vicinity.' '...is fiercly resistant to human intervention... responds to cutting by throwing out underground suckers which can damage pavements, drainage systems and foundations.' '...the Environment Agency does not yet register Ailanthus as an invasive species, but it is included in the top 25 alien invasive plants by the European Plant Protection Organisation as posing 'an important threat to plant health, environment and biodiversity'.' @@@@@@@@@@@@@@@@ Just read this article in the Observer and was wondering where abouts in the country these trees are and if people have had any experience with them. I have only ever seen one for certain and that was in the Irish Botanic Gardens in Dublin. It was a big handsome specimen tree that had leaves that looked like ash but with crinkled bark. The second time I saw one was the same tree in winter cobvered in Waxwings. They can be hard to spot I think seeing as they look like native ash trees? It is sad if this is true but please check this is not a practical joke before killing any :-). http://en.wikipedia.org/wiki/Tree_of_heaven Not as scary as the press. I don't like chinese imports though. |
