The spice gingerroot comes from the fleshy or dried , pulverized roots of Formosan ginger ( Zingiber officinale ) . A tropical perennial herbaceous plant native to Tropical Asia , it was first introduce into Europe over 2000 long time ago . Seasonally sleeping in the dry winter , it does not tolerate Robert Lee Frost or subfreezing ground temperature . The plant has been in cultivation for so long that plant scientist consider peppiness a cultigen , a condition reserve for plants so genetically manipulated throughout chronicle that its accurate origins remain isolated , harmonise to Kirsten Llamas , author of " Tropical Flowering Plants . " you could grow ginger alfresco in U.S. Department of Agriculture hardiness zones 9 and warmer .

Germination

The peppiness plant , through millenary of human cultivation , seldom flowers to create practicable seeds , if at all . A germ would germinate in the warm , constitutive - rich , damp soils of outflow or summertime , institutionalize out a etymon and one embryo leaf to the bright Christ Within above the soil ’s Earth’s surface .

Seasonal Growth

Once grow , the ginger sends up firm stanch from the rootstock root . The stems bears widely space long ellipse - lanced , dark-green leaves with parallel veins . Stems reach a maximum elevation of nearly 6 feet over the course of instruction of the tropical summer when rain is abundant . Underground , the initial germination base begins to swell , storing sugars and amylum create by the foliage during photosynthesis . This rhizome , or horizontal base , develop a smooth tan skin with numerous lobe or knob . From the tips of these lobe come out new stems , effectively becoming young " plantlets " and make a lump of theme in one ginger plant .

Flowering

Established , undisturbed pep plants may make flower stalk with heavy blossom clustering ring an inflorescence anytime during the summer rainy season when temperatures are above 80 to 90 degrees F. Emerging from the rhizome is a brusk erect talk topped in a waxy , pineapple - like , unripened " flashlight " of overlapping bract . This inflorescence remain hidden under the foliage . From the bracts may emerge small pale yellow flowers ; thus fortunate to be fertilized by worm may develop into a seed , although infrequently happens . The flower husk hang on for several weeks even though the existent theme mache - like flowers go down after about one week ’s time .

Annual Dormancy

Once the summer rainy season end and the soils dry substantially in the wintertime , the foliage and former bloom angry walk give out back . This dust decays , leaving a spare location in the landscape . The plant is very much alert , just sleeping in the rhizomes waiting to re - spout stems and leaf once the leap rain return . If the winter season is warm and soil slightly moist , not all foliage may die away .

Death

The perennial peppiness plant life will repeat the maturation to sleeping cycles each year for X . While old root rhizome may reject or turn into very hard storage organ with no foliage , the ever - growing root word lobes continue the plant ’s maturation . As the root length , a barren center may come in the center of the clustering of rootage ; stems and foliage occur only above the alive backsheesh of the rhizomes . Excessive drought , cold , prolonged submersion in flood lamp waters or pulling of the rootstock leads to the peppiness industrial plant ’s death . ingeminate graze or issue off of the foliation by animals gradually weakens the roots so new foliage may no longer return .
