Fennel (Foeniculum vulgare)

The leaves of the sun-hungry umbellifer, which grows up to two meters high, are strongly pinnate, so that only a little water evaporates over the small leaf surface. Another adaptation of the fennel to the dry locations of its original home on the Mediterranean are the thickened lower leaf stalks. They form a pseudotuber with a storage function, which is particularly fleshy in the case of vegetable fennel. The yellow flowers of the fennel appear from July to September in large, plate-shaped double umbels.

Origin and cultivation.

Wild fennel is found only sporadically in Italy and on the Iberian Peninsula. But fennel has been cultivated since time immemorial, three subspecies are the result of constant selection. The light green to whitish bulbs of the vegetable fennel are used in cooking. The fennel seeds - botanically speaking, they are fruits because the seed is still stuck together with a pericarp - are also in demand: the seeds of sweet fennel (also called "Roman fennel") are used as a spice; seeds for medicinal use are harvested from bitter fennel.

Ingredients.

Fennel oil is found only in very small quantities in the leaves, but the seeds contain up to six percent of this essential oil, depending on the cultivation. It consists of over 50 percent anethole, which is responsible for the typical fennel aroma. Anethole not only has an antispasmodic and expectorant effect, but also supports the muscles of the stomach and intestines and stimulates milk production. Another component of fennel oil is the germ-inhibiting fenchone, which is responsible for the bitter taste. Bitter fennel contains about 10 to 20 percent fenchone, while sweet fennel contains less than one percent.

Use of fennel oil.

  • Tea from fennel seeds relieves flatulence and other digestive problems of infants and young children. Most children like the taste of fennel, which is much milder and sweeter than that of the similarly effective caraway
  • The expectorant effect of fennel is particularly well demonstrated in the form of the old home remedy fennel honey: The mixture of honey and fennel or fennel oil helps children and adults with colds and coughs. However, some ready-made products consist only of sugar solution with a little honey and fennel extract. Fennel honey is an insider's tip for singers against hoarseness
  • the fine aroma of fennel oil is also appreciated in sweets, liqueurs, soaps and toothpaste. A few chewed fennel seeds help against bad breath.
Special.

Hildegard of Bingen (1098-1179) was a big fan of fennel: "However it is eaten, it makes a person cheerful and imparts pleasant warmth and good sweat and digestion."

The more than 600 species of eucalyptus are native to Australia and eastern Indonesia. With heights of up to 100 meters, some species of the evergreen and mostly fast-growing trees are among the largest on earth. The blue-green, leathery leaves are still ovate on young trees, later forming crescent-shaped, drooping forms. The feathery flowers are protected by a tight lid before they bloom, hence the name: in Greek, "eu" means good and "kalyptos" means hidden.

Free-standing spruces grow 30 to 40 meters high, in dense stands they even stretch to 60 meters. Their sharp, piercing needles sit on small stems, and the hanging cones fall to the ground as "fir cones" in the fall. The spruce was named Tree of the Year 2017 because it does not tolerate a lack of water or waterlogging. It will therefore not cope well with the expected climatic changes - Germany's most common tree species could soon become rare.
