2011-10-09 Vienna XXII. district, Lobau - Danube National Park (155 msm Quadrant 7864/2).German name: Nessel-Teufelszwirn, Nessel-Seide; Riesen-GoldruteSolidago is a new-found host of Cuscuta which prefers native Urtica (and a few other species); last year I found that Cuscuta is not as vital on Solidago as it is on Urtica (it only bore few fruit on the former), and the same was true this year - only that this year's growth of Cuscuta was much richer, and it reached fruiting stage on many Soldiago plants too - like on this one here.For more photos from the same habitat click here!

2010-08-25 Vienna XXII. district (Lobau brownlands, 155 m AMSL).Flower and fruit; here on Solidago gigantea (subsp. serotina): an untypical host.I've found some who died on Solidago before they could flower and fruit: so obviously it isn't too vital on Solidago, but it can survive there.German name: Nessel-Teufelszwirn (-Seide)For more photos from the same habitat click here!
2008.08.05: Austria, Vienna XXII. district, 155 m AMSL, fallow land (Lobau national park).Flowering from july/august till october.Very common, invasive (native of North America).German name: Riesen-Goldrute.ID: Fischer, Exkursionsflora 3rd; oftentimes mistaken for Solidago canadensis (I made the same error myself): the latter has a hairy stem while the former hasn't, or has at most some hair on its inflorescence (which usually is the case for populations in Lobau). Instead, the stem of S. gigantea has a 'floured' look, and you can wipe it off, as is shown here.
2010.07.25 Vienna XXII. (Lobau Hubertusdamm 155 m AMSL).Flower; note how the stems in the inflorescence are arcing, which is typical for this species (while they're straight with others).German name: Gross-GoldruteID: Fischer & al., Exkursionsflora (2008 3rd)
2010.07.25 Vienna XXII. (Lobau Hubertusdamm 155 m AMSL).Stem and leaf; note the 'floury' coating of the stem which you can brush away (I did so here, for illustrative reasons; see note above) - one of the easily detectable distinctive features of this species.German name: Gross-GoldruteID: Fischer & al., Exkursionsflora (2008 3rd)
