Plants in peatlands survive low numbers of pollinators by staggering their flowering times.
"Many plant species depend on insect pollinators, and such insects are often rare on peatlands. Bog dwarf shrubs have separated flowering times. For instance, in Ontario the flowering sequence is Chamaedaphne calyculata, Andromeda glaucophylla, Kalmia polifolia, Rhododendron groenlandicum, Vaccinium macrocarpon (with wide overlap in flowering time only between Andromeda and Kalmia). The pollinators (e.g. bees) are quite generalist and serve several species, so it may well be that the differentiation in flowering time has evolved to avoid competition for pollinators (Reader 1975)."
