Tall pines, a thin growth, stood wherever we turned our eyes, and the ground was covered with the dwarf palmetto, and the whortleberry, which is here an evergreen.
Only a few plants, such as the grouse whortleberry (Vaccinium scoparium) and elk sedge (Carex geyeri), grew in the dense shade.
The sequel, Edwardian Farm begins tonight – a 12-parter this time, on rural life at the turn of the century, covering everything from goat-rearing to whortleberry selling.
Understory growth is not luxuriant, consisting mostly of grouse whortleberry, Oregon grape, and birchleaf spirea.
Sami reindeer herders from Kaldoaivi in Utsjoki have observed that berries such as bog whortleberry ( '' Vaccinium uliginosum '') have almost disappeared in some areas.
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 .
In the subarctic, measurements of stem length, branching, leaf thickness, flowering, berry production, phenology, and total UV-B radiation absorbing compounds were affected significantly by ambient UV-B radiation levels in only two of three dwarf shrubs (i.e., bog whortleberry and lingonberry ).
Increased CO2 concentrations interacted with high UV-B radiation levels to increase leaf ice nucleation temperature by 5 °C in bog whortleberry.
A combination of elevated CO2 and UV-B radiation levels increased late-season frost sensitivity of leaves of bog whortleberry from -11.5 to -6 °C.
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.
