Identification

This is a widely recognized, 2 to 12 tall, erect, perennial forb. It rises on up to 20 or more basal leaves and 1 to 10 or more flowering stems (scapes) from a deep, somewhat fleshy, seldom branched taproot. When broken the scapes and leaves exude a milky latex.

The leaves are all basal, 2 to 18 long, and ¾ to 4 wide. They are erect to horizontal. They may be shallowly or deeply lobed (pinnatifid), sometimes cut nearly to the midrib. They are often deeply pinnatifid with the lobe ends pointing downwards. The terminal lobe is usually larger than the lateral lobes. Smaller leaves may be unlobed. The upper surface is hairless. The underside has woolly hairs along the midveins and sparse woolly hairs on the surface. The margins may be toothed or untoothed.

The flowering stems are erect or ascending, hollow, leafless, and hairless or with sparse, woolly hairs. They are ¾ to 16 long, usually as long or longer than the leaves.

The inflorescence is a solitary flower head at the end of each scape.

The involucre is composed of an inner series of usually 13 to 20 bracts and an outer series of 11 to 17 bracts. The bracts are often purple tinged toward the tip. The inner bracts are fused at the base with the tips erect at first, later bent backward. They form an urn-shaped or cup-shaped structure that does not have small, horn-like protuberances. The outer bracts are similar in shape but about half as long or less than the inner series. They bend back sharply as the head first develops.

The flower heads are 1 to 2 wide. They are composed of 40 to 120 or more bright yellow, strap-shaped ray florets and no disk florets.

The fruiting head is a whitish, spherical mass with a feathery appearance. The fruit is an olive-colored to greenish-brown achene with a tuft of white hairs attached at the tip. They are dispersed by wind.

Species

Red-seeded dandelion (Taraxacum erythrospermum) leaves have terminal lobes that are smaller or at least no wider than the 2 adjacent lateral lobes. The flower heads are no more than 1 across. The achene is reddish-brown.

Dandelion - Taraxacum officinale (cc) There are fields and fields of blooming dandelion throughout British Columbia in the spring time. Although we have been conditioned to think of them as noxious weeds best dealt with chemical poisons, there are other uses for dandelions.

Small birds are very fond of the seeds of the Dandelion and pigs devour the whole plant greedily. Goats will eat it, but sheep and cattle do not care for it, though it is said to increase the milk of cows when eaten by them. Horses refuse to touch this plant, not appreciating its bitter juice. It is valuable food for rabbits and may be given them from April to September forming excellent food in spring and at breeding seasons in particular.

The young leaves of the Dandelion make an agreeable and wholesome addition to spring salads and are often eaten on the Continent, especially in France. The full-grown leaves should not be taken, being too bitter, but the young leaves, especially if blanched, make an excellent salad, either alone or in combination with other plants, lettuce, shallot tops or chives.

Young Dandelion leaves make delicious sandwiches, the tender leaves being laid between slices of bread and butter and sprinkled with salt. The addition of a little lemon-juice and pepper varies the flavour. The leaves should always be torn to pieces, rather than cut, in order to keep the flavour.

In Berkshire and Worcestershire, the flowers are used in the preparation of a beverage known as Dandelion Wine. This is made by pouring a gallon of boiling water over a gallon of the flowers. After being well stirred, it is covered with a blanket and allowed to stand for three days, being stirred again at intervals, after which it is strained and the liquor boiled for 30 minutes, with the addition of 3 1/2 lb. of loaf sugar, a little ginger sliced, the rind of 1 orange and 1 lemon sliced. When cold, a little yeast is placed in it on a piece of toast, producing fermentation. It is then covered over and allowed to stand two days until it has ceased 'working,' when it is placed in a cask, well bunged down for two months before bottling. This wine is suggestive of sherry slightly flat, and has the deserved reputation of being an excellent tonic, extremely good for the blood.

The roasted roots are largely used to form Dandelion Coffee, being first thoroughly cleaned, then dried by artificial heat, and slightly roasted till they are the tint of coffee, when they are ground ready for use. The roots are taken up in the autumn, being then most fitted for this purpose. The prepared powder is said to be almost indistinguishable from real coffee, and is claimed to be an improvement to inferior coffee, which is often an adulterated product. Of late years, Dandelion Coffee has come more into use in this country, being obtainable at most vegetarian restaurants and stores. Formerly it used occasionally to be given for medicinal purposes, generally mixed with true coffee to give it a better flavour. The ground root was sometimes mixed with chocolate for a similar purpose. Dandelion Coffee is a natural beverage without any of the injurious effects that ordinary tea and coffee have on the nerves and digestive organs. It exercises a stimulating influence over the whole system, helping the liver and kidneys to do their work and keeping the bowels in a healthy condition, so that it offers great advantages to dyspeptics and does not cause wakefulness.

Location: Everywhere right now.

They are coming up like never seen before.  50 to 100 plants per square foot. It seams like "the year of the dandelion".  I'm curious if we will see some other "bloom" in nature, like an over abundance in spiders or other insects?
