Populus tremuloides

Populus tremuloides

Quaking Aspen

Populus tremuloides is a deciduous tree native to cooler areas of North America. The species is referred to Quaking Aspen, Trembling Aspen, and Quakies, names deriving from its leaves which flutter in the breeze. The tree-like plant has tall trunks, up to 25 metres, with smooth pale bark, scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in Autumn. The species rarely flowers, often propagating through its roots to form large groves.

It propagates itself primarily through root sprouts, and extensive clonal colonies are common. Each colony is its own clone, and all trees in the clone have identical characteristics and share a single root structure. A clone may turn color earlier or later in the fall than its neighbouring aspen clones. Fall colors are usually bright tones of yellow; in some areas, red blushes may be occasionally seen. As all trees in a given clonal colony are considered part of the same organism, one clonal colony is considered the heaviest and oldest living organism at six million kilograms and approximately 80,000 years old.

Fenestraria is a monotypic genus of succulent plants in the family Aizoaceae. The species is also called babies toes or window plant. On each leaf there is transparent window-like area at the top, it is for these window-like structures that the genus is named (Latin: fenestra). In the wild, the plant grows mostly buried by sand. The transparent tips are often above the sand and allow light into the leaves for photosynthesis. F. rhopalophylla is native to Namibia and Namaqualand in southern Africa. The plants are generally found growing in sandy or calciferous soils under low < 100 mm rainfall.

Hemerocallis sp.

Hemerocallis sp.

Daylily

Daylily is the common name of the species, hybrids and cultivars of the genus Hemerocallis . The flowers of these plants are highly diverse in colour and form, often resulting from hybridization by gardening enthusiasts. Once considered part of the Liliaceae family, such as Lilium (true lilies), the genus name was given to the family Hemerocallidaceae in later circumscriptions.

The flowers of some species are edible and are used in Chinese cuisine. They are sold (fresh or dried) in Asian markets as gum jum or golden needles or yellow flower vegetables . They are used in hot and sour soup, daylily soup, Buddha's delight, and moo shu pork. The young green leaves and the tubers of some (but not all species are also edible. The plant has also been used for medicinal purposes. Care must be used as some species can be toxic.
