Peat Moss, also called sphagnum moss and bog moss, common name for about 300 species of moss plants that grow in swamps and bogs throughout the world. Peat moss may grow to 30 cm (12 in) or more in height. The plants have many branches covered with small, light green leaves. The leaves and stems have special cells that absorb and hold much water. Peat moss is one of the most common plants from which peat, a fuel, is produced. When the plants die, the dead organic matter is preserved more or less intact because the moss is acidic, so bacterial and fungal decay occurs slowly. The dead peat moss and other plants are compressed by the weight of the living plants growing above them. This compressed matter eventually forms the peat. The peat can be cut into blocks and removed for use as fuel. Peat moss is also useful in gardening. It combats excessive alkalinity in the soil and produces the acid environment that certain plants need to grow, including such ornamental shrubs as rhododendro...

A small bryophyte plants belonging to the phylum Anthocerophyta; any of several submerged plants of the genus Ceratophyllum, forming branched masses in quiet water and having finely dissected, whorled leaves and minute unisexual flowers.  Unlike liverworts but like mosses, hornwort sporophytes have stomata. The hornwort gametophyte consists of a low thallus, out of which numerous slender, upright sporophytes tipped with sporangia grow. The sporophyte has a meristem that elongates the sporophyte with new growth, a feature that distinguishes the plant from the other bryophytes. The name of the hornworts was suggested by the hornlike appearance of the sporophytes.

Calabash Tree (Crescentia cujete) of the trumpet-creeper family (Bignoniaceae), 6 to 12 metres (20 to 40 feet) tall, that grows in Central and South America, the West Indies, and extreme southern Florida. It is often grown as an ornamental. It produces large spherical fruits, up to 50 cm (20 inches) in diameter, the hard shells of which are useful as bowls, cups, and other water containers when hollowed out. The fruit's shell encloses a whitish pulp and thin, dark brown seeds. The tree bears funnel-shaped, light green and purple-streaked flowers and evergreen leaves. Fruits of the unrelated bottle gourd (Lagenaria siceraria) are also known as calabashes. In some countries the rind and juice are used for medicinal purposes.

Rye, cereal grain of the family Gramineae (grass family). The grain, Secale cereale, is important chiefly in Central and N Europe. It seems to have been domesticated later than wheat and other staple grains; cultivated rye is quite similar to the wild forms and no traces of it have been found among Egyptian ruins or Swiss lake dwellings. Where it grows well, wheat is preferred, but rye will produce a good crop on soil too poor or in a climate too cool to produce a good crop of wheat. The standard schwarzbrot, or pumpernickel, of Europe was formerly the major rye product. A bread of lighter color, called rye bread, is made of rye flour mixed with wheat flour. Today rye is used mostly as a stock feed (usually mixed with other grains), for hay and pasturage, for green manure, and as a cover crop. Russia leads in world production. Rye is much used as a distillers' grain in making whisky and gin. The tough straw of rye is valued for many purposes, e.g., thatching for roofs and stuffing ...

Shadbush, Juneberry, or serviceberry, any species of the genus Amelanchier of the family Rosaceae (rose family), chiefly North American shrubs or trees conspicuous in the early spring for their white blossoms. The bush is more often called shadbush on the East Coast (it is said to bloom when the shad are running); serviceberry is in general a Western name. The huckleberrylike fruits of native species were eaten by the Native Americans and are still sometimes collected. They are an important wildlife food. Some kinds of shadbush are cultivated for ornament. The wood is very hard. Shadbushes are classified in the division Magnoliophyta, class Magnoliopsida, order Rosales, family Rosaceae.

Cinquefoil (sĭngk`foil) [O.Fr.,=five leaves], name for any plant of the widely distributed genus Potentilla of the family Rosaceae (rose family), chiefly herbs of north temperate and subarctic regions. Most cinquefoils are perennial; many but not all of them have leaves of five leaflets, for which they are also called five-finger. The flowers are most often yellow. Most North American species are native to cooler regions of the W United States. The shrubby cinquefoil (P. fruticosa) and the silverweed (P. anserina) are common wildflowers in the West and the Northeast; they are thought to be naturalized from the Old World. These and other species are sometimes cultivated in rock gardens. Silverweed is one of the species reputed to have medicinal powers, hence the Latin name of the genus [potens=powerful]. Cinquefoil is classified in the division Magnoliophyta, class Magnoliopsida, order Rosales, family Rosaceae.

Strawberry, any plant of the genus Fragaria of the family Rosaceae (rose family), low herbaceous perennials with edible red fruits, native to temperate and mountainous tropical regions. The European everbearing strawberry (F. vesca) is the only species that does not put out the stolons typical of this easily propagated genus. It has been cultivated sporadically since pre-Christian times but intensively only since the 15th cent. The common strawberry, grown in many varieties in both Europe and America, is Fragaria × Ananassa, the result of the hybridization of F. chiloensis, believed to be indigenous to Chile and to the mountains of W North America, with the wild strawberry (F. virginiana) of E North America. Both species were introduced to Europe by New World explorers; the large French industry grew from a single common strawberry plant. Strawberries are sold fresh, frozen, or in preserves and are used in confectionery and for flavoring. Strawberries are classified in the division Mag...
