Jicama is one species in the genus Pachyrhizus that is commonly called yam bean, although the “yam bean” sometimes is another name for Jicama. The other, major species of yam beans arealso indigenous within the Americas. In India it is called Sankalu

 

Habitat :Jicama  is native to maxico but now it grows in  many tropical cuntries

Description:The jicama vine can reach a height of 4-5 metres given suitable support. Its root can attain lengths of up to 2 m and weigh up to 20 kilograms. The root’s exterior is yellow and papery, while its inside is creamy white with a crisp texture that resembles raw potato or pear. The flavor is sweet and starchy, reminiscent of some apples, and it is usually eaten raw, sometimes with salt, lemon, or lime juice and chili powder. It is also cooked in soups and stir-fried dishes.

Jicama is a tropical plant and thus requires at least 9 months of warm growing season for good sized roots to mature. However, if soil is rich, light and there is at least 4 months of warm weather available, the resulting roots will be smaller, but still quite delicious. Presoak seeds in water for about 24 hours before planting. Can be started indoors about 8 to 10 weeks before the last spring frost. Transplant into your garden as soon is weather is warm, but be careful where you plant it as the ripe pods, leaves and seeds are toxic and narcotic. Care should be taken so that no humans or animals will mistakenly eat these parts. The immature seed pods are edible as well as of course the turnip like roots for which it is grown. Can be grown near a trellis for support or like pole beans. Can also be grown on the ground but then requires a lot of space. When they grow to about 3 feet tall, pinch the tips to promote horizontal branches. Tubers form as the days grow shorter and should be harvested before the first frost. If you allow the plants to go to seed, the root lobes will be small. Blossoms appear in late summer, but can be pinched out for maximum root growth.

Due to its growing popularity, cultivation of jícama has recently spread from Mexico to other parts of Central America, China and Southeast Asia where notable uses of raw jícama include popiah and salads such as yusheng and rojak. Jícama has become popular in Vietnamese food,  In Mexico it is very popular in salads, fresh fruit combos, fruit bars, soups, and other cooked dishes.

Edible Uses:

Standard Uses: This is an unusual vegetable that is becoming increasingly popular with American cooks, but has been grown in its native Mexico for centuries. More and more U.S. supermarkets are now carrying this turnip shaped, usually four lobed root. Its skin is a brownish gray, but its flesh is white and crisp. It’s flavor resembles that of water chestnuts but is sweeter. Makes a great appetizer and is a very good addition in both taste and texture when added to salads.

While many vegetables and fruits are common, others are not, but that doesn’t mean they’re not an excellent food – just unfamiliar. For one thing, jicama plants thrive in tropical regions.

Like other foods, jicama contains real culinary goodness: sliced and baked, julienned in salad, chopped in stir-fries and soups, and mixed with other veggies and fruits to emphasize its sweetness or starchy texture. Just remember to eat only the root, since the other parts may be toxic.

So if you haven’t experienced jicama in your dining repertoire, you have everything to gain – and if you’re actually hoping to lose, this might be your new favorite.

Jicama : Kitchen & Cooking Tips

Health benefits, and the common uses for Jicama in cooking.

Medicinal Uses: .

Low in calories but high in a few vital nutrients, jicama is a bit of a contradiction when it comes to its starch content. It provides one-quarter of what’s needed daily in fiber per serving. But not just any fiber – jicama’s fiber is infused with oligofructose inulin, which has zero calories and doesn’t metabolize in the body. Inulin, a fructan, promotes bone health by enhancing absorption of calcium from other foods, protecting against osteoporosis. Inulin has a prebiotic role in the intestine – it promotes “good” bacteria growth that maintains both a healthy colon and balanced immunity. Because it has a very low glycemic index, jicama is a great food for diabetics, and low in calories for those interested in weight reduction.

Jicama is also an excellent source of fiber and vitamin C – 44% of the daily value per serving – and a powerful antioxidant that zaps free radicals to protect against cancer, inflammation, viral cough, cold, and infections.

Jicama is starchy. The most interesting health benefit related to jicama is the inulin, which studies have shown can protect against osteoarthritis, and have a positive impact on colorectal cancer, especially when eaten during its early stages. Studies are increasing on this root veggie that has until recently been quite overlooked.

Besides healthy amounts of potassium, this little powerhouse can help promote heart health, since high-potassium vegetables and fruit are linked to lower risks of heart disease. Jicama contains important vitamins like folates, riboflavin, pyridoxine, pantothenic acid, and thiamin, and the minerals magnesium, copper, iron, and manganese. Like potatoes, they should be used sparingly due to the high carbohydrates content.

Other Uses:

Jicama is a vine plant that makes an attractive ornament, deserving a place in your flower garden. It blooms profusely with white to lavender colored flowers that resemble sweet peas. Its leaves are heart shaped and large.click & see

Studies on Jicama:

A study published in the British Journal of Nutrition in 2005 showed that foods containing inulin, such as jicama, lower colon cancer risks in several ways, which include reducing exposure as well as the toxic impact of carcinogens in the gut, and inhibiting the growth and spread of colon cancer to other areas of the body. Scientists concluded that inulin-type fructans may reduce colorectal cancer incidence when given during early stages of cancer development.

Jícama is high in carbohydrates in the form of dietary fiber. It is composed of 86-90% water; it contains only trace amounts of protein and lipids. Its sweet flavour comes from the oligofructose inulin (also called fructo-oligosaccharide).

 

Known Hazards:The leaves, ripe seed pods and seeds are toxic and narcotic  .  In contrast to the root, the remainder of the jícama plant is very poisonous; the seeds contain the toxin rotenone, which is used to poison insects and fish.

The scientific name for Hollyhocks is Alcea rosea but used to go by the scientific name Althaea and is still seen that way in garden catalogs on occasion.

Common Name:Hollyhocks

Habitats: Holyhock is native to Eurasia.It grows in Woodland Garden; Sunny Edge; Dappled Shade; and in  Cultivated Beds.Hollyhocks prefer rich, well-drained soil and full sun. Light shade is tolerated but wet winter soil is not….click & see

Description:
Holyhock  is a biennial or short-lived perennial plant about 4-8′ tall. The stout central stem is unbranched or sparingly branched; it is light green, terete, and more or less hairy. The blades of the alternate leaves are up to 8″ long and across; they are palmately lobed (with 3-7 blunt lobes each) and crenate along their margins. Each leaf blade is orbicular or oval in outline and indented at the base where the petiole joins the blade. The upper surface of each leaf blade is medium green, slightly pubescent to hairless, and wrinkled from fine veins; the lower surface is light green and pubescent. The petioles of the leaves are as long or a little longer than their blades; they are light green and hairy..

The central stem terminates in a spike-like raceme of flowers; axillary flowers are produced from the axils of the upper leaves as well. These flowers occur individually or in small clusters along the central stem; they nod sideways from short hairy pedicels. Each flower spans about 3-5″ when it is fully open; it has 5 petals, 5 sepals, 6-9 sepal-like bracts, and a columnar structure in the center with the reproductive organs (stamens toward the tip, thread-like stigmas below). The overlapping petals provide the flower with a funnelform shape; they are usually some shade of white, pink, or purplish red. The sepals are light green, ovate, and much smaller than the petals. The bracts of each flower are located underneath the sepals; they are light green, hairy, ovate, and joined together at the base. The blooming period occurs from mid-summer into the fall; a colony of plants will bloom for about 2 months. Each flower is replaced by a fruit containing a ring of 15-20 seeds (technically, a schizocarp). These seeds are oval, flattened, and notched on one side. The root system consists of a taproot. This plant spreads by reseeding itself.

Uses in the Garden: Perfect for planting in the back of borders, for old cottage gardens, cut flower gardens, humming bird beds or fence borders.

Cultivation details:
Succeeds in most soils. Poor soils should be enriched with organic matter. Prefers a heavy rich soil and a sheltered sunny position.Plants are hardy to about -15°c.A very ornamental plant, it is usually grown as a biennial due to its susceptibility to the fungal disease ‘rust’. There are many named varieties.Young plants, and also the young growth in spring, are very attractive to slugs. The preference is full to partial sun, moist to mesic conditions, and a fertile loamy soil. Lower leaves will wither away during hot dry weather. Hollyhock is vulnerable to foliar disease, including rust.

Propagation:
Seed – sow April/May or August/September in pots or in situ[200, 238]. Easily grown from seed, which usually germinates in about 2 – 3 weeks at 20°c[133, 268]. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.Division after flowering. Only use rust-free specimens.Root cuttings in December.Basal cuttings at almost any time of year

Medicinal Uses:
Antiinflammatory; Astringent; Demulcent; Diuretic; Emollient; Febrifuge.

Hollyhock is stated to be an emollient and laxative. It is used to control inflammation, to stop bed-wetting and as a mouthwash in cases of bleeding gums .

The flowers are demulcent, diuretic and emollient. They are useful in the treatment of chest complaints, and a decoction is used to improve blood circulation, for the treatment of constipation, dysmenorrhoea, haemorrhage etc. The flowers are harvested when they are open and are dried for later use.
The shoots are used to ease a difficult labour. The root is astringent and demulcent. It is crushed and applied as a poultice to ulcers. Internally, it is used in the treatment of dysentery. The roots and the flowers are used in Tibetan medicine, where they are said to have a sweet, acrid taste and a neutral potency. They are used in the treatment of inflammations of the kidneys/womb, vaginal/seminal discharge, and the roots on their own are used to treat loss of appetite.
The seed is demulcent, diuretic and febrifuge.The flowers are used in the treatment of repiratory and inflammatory ailments and the root extracts to produce marshmallow sweets.

Other Uses
Compost; Dye; Litmus; Oil; Paper.
A fibre obtained from the stems is used in papermaking. The fibres are about 1.9mm long. The stems are harvested in late summer, the leaves are removed and the stems are steamed until the fibres can be removed. The fibres are cooked with lye for 2 hours and then ball milled for 3 hours or pounded with mallets. The paper is light tan in colour.

The flowers are an alternative ingredient of ‘Quick Return’ herbal compost activator. This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost.The seed contains 12% of a drying oil.The red anthocyanin constituent of the flowers is used as a litmus.A brown dye is obtained from the petals.
Hollyhocks are tolerant of black walnut toxins and, like Polemonium plants, can be planted near and around black walnut trees where other plants will not grow.
