Petunia Hedgiflora

Above: ground-cover petunias of the (silver) tidal wave variety.

One of the most popular annual plants, petunias exude a nice perfume and are often considered a staple of American gardening, from hanging baskets (grandiflora) to populating considerable swaths of hillside or lawn (hedgiflora). Many color varieties exist as well, and petunias (when provided ample sunlight and planted in soil that drains moderately well) often bloom from after frost until the end of the summer, making them extremely easy to grow and cultivate.

Cetraria Islandica

Iceland moss is actually a lichen; its "moss" nomenclature most likely resulted from its appearance, which presents common aspects of other mosses (ascending, erect foliation).

Coloration ranges from a lively green to a greyish, almost snowlike white. And although it grows abundantly in the western and northern plains of Iceland, it can be found in various (mountainous/northern) regions of Wales, Scotland, Alaska, Colorado, and New England.
