Description |
||
The stem is hairless, often glaucous, and often tinged reddish-purple. With some well known exceptions, goldenrods are notoriously difficult to identify in the field. Giant goldenrod is one of those exceptions. It is the only goldenrod in Minnesota with a stem that is both hairless and glaucous. It is the only hairless goldenrod in Minnesota that gets more than 3′ tall. It is the only goldenrod with a hairless stem that may have a globular gall on the stem. The gall is produced by the goldenrod gall fly and is very common, occurring almost everywhere giant goldenrod is found. |

Published on Sep 4, 2012 Solidage géant, ou Solidage glabre, une plante à fleurs jaunes venue tout droit du continent nord-américain, une plante qui depuis s'est trop bien acclimatée et qui devient invasive et une menace pour la flore locale, elle est sur la liste noire de quelques pays, liste qui va sans doute s'étendre ! http://www.champyves.fr/nature/FicsHtml/F_J_Solidago_gigantea.htm |
