Fun Facts about Geraniums ◆ ◆ Their leaves often smell of peppermint, chocolate or other fragrances but the flowers can also be odorless. ◆ ◆ Geranium can reach from 6 inches to 3 - 4 feet in height, depending on the species. ◆ ◆ Geranium develops elongated, palmately divided leaves with serrated edges. Most species of gera- nium have green leaves. Some varieties develop yellow, orange or red-colored leaves. ◆ ◆ Geranium produces individual flowers that can be white, red, pink, purple or blue colored. Some va- rieties of geranium produce double blooms (flow- ers with 2 or more rows of extra petals). ◆ ◆ Geranium blooms from early spring until the late autumn. The flowers are a rich source of nectar which attracts bees, bumblebees, flies and beetles, which are responsible for the pollination of these plants. 36 of geranium is elongated capsule with a beak-like tip. Capsule is filled with 5 seed. It resembles the crane’s bill, hence the nickname “cranesbill”. Ripe fruit splits explosively and ejects seed away from the mother plant. ◆ ◆ Geranium propagates via seed and cuttings. ◆ ◆ Flowers of geranium are good source of essential oils that can be used for the removal of scars from the surface of the skin. The root of geranium con- tains compounds that are effective in treatment of excessive bleeding, conjunctivitis, retinal disorders and hemorrhoids. Root also has antiseptic proper- ties (prevents growth of harmful microorganisms) and ability to relieve symptoms of diarrhea and irritable bowel syndrome. Extract of geranium root is available in the form of capsules and tinctures. ◆ ◆ Flowers of some types of geranium have rose-like scent. Essential oils extracted from those plants are used for the manufacture of artificial rose oil in the perfume industry. Rose-scented geraniums can be also used as flavoring agent for jellies and cakes. ◆ ◆ Leaves of geranium can be used for the prepara- tion of tea. ◆ ◆ Citronella-scented geranium repels mosquitoes and can be used as natural insect repellent, in- stead of chemical, industrially manufactured insec- ticides. ◆ ◆ Geranium belongs to the group of low-mainte- nance plants. It is frequently cultivated in gardens because of its ornamental, colorful flowers. ◆ ◆ Geranium grows as annual (lifespan: one year), bi- ennial (lifespan: 2 years) or perennial plant (lifes- pan: more than 2 years), depending on the species and climate. www.GardenandGreenhouse.net November 2018
