The sweet-scented geranium abounded and so did the crowberry, which is a finer and sweeter kind than that which grows nearer the settlement.
In contrast, K. Taulavuori et al. , found decreased frost resistance in bilberry in response to elevated UV-B radiation levels and Beerling et al.  showed decreased frost resistance in bog whortleberry, lingonberry, and mountain crowberry.
Bog whortleberry (or bog bilberry – '' Vaccinium uliginosum ''), lingonberry, and mountain crowberry showed increases in leaf ice nucleation temperature exceeding 2.5 °C whereas bilberry showed no significant effect, as in another study .
Mountain crowberry and lingonberry showed no responses to enhanced UV-B radiation levels after seven years of exposure whereas bog whortleberry and bilberry showed few responses (Table 7.6).
Four dwarf shrubs were studied over the first three years of the experiment; one, the deciduous bilberry, showed increased annual stem growth (length) in the first year whereas two other evergreen dwarf shrubs (mountain crowberry – '' Empetrum hermaphroditum '' and lingonberry) showed reduced growth.
Laine  showed that the reproduction of bilberry ( '' Vaccinium myrtillus '') depended to some extent on the climate in the previous years (see section 14.7.3 for examples of this in trees), whereas Shevtsova et al.  showed no such response for co-occurring lingonberry and crowberry ( '' Empetrum nigrum '').
It consists chiefly of low mats of such herbaceous and shrubby species as dwarf arctic birch, crowberry, Labrador-tea, arctic willow, resin birch, and dwarf blueberry.
Typical species are dwarf birch Betula nana, Arctic crowberry Empetrum nigrum ssp. hermaphroditum and Arctic blueberry Vaccinium uliginosum ssp. microphyllum.
The dwarf scrub communities are dominated by crowberry (Empetrum nigrum) and include other ericads (Vaccinium spp.), arctic willow (Salix arctica), and white mountain-avens (Dryas octopetala).
This is a diverse community of ferns, sedges, grasses, angiosperms and mosses and is dominated by B. palmiforme, crowberry Empetrum rumbrum, grasses and sedges.
