Tropical plants are known for their spectacular foliage and often breathtaking flowers , as well as their love of heat and sunlight . Buthidden gingers(Curcuma petiolata ) loosely want shade for their best performance , as the leaves curl when the works get too much sun . In a shady domain , the plants sports broad , flattened leaves .
Sunlight Requirements
The defensive curling of concealed ginger leaves outcome from too many hours of direct Sunday during the hot parts of the daytime . A bit of break of the day Dominicus is fine , but as the day march on , the luminousness becomes too acute for secret gingers , which reply by roll their leaves down and inward to reduce the overall aerofoil surface area let on to the sun . Though hidden gingers are tropic plant life , and produce in U.S. Department of Agriculture plant hardiness zones 8 through 10 , they are understory plants in their native habitats . They favour part shade , no more than three hours in the morning , to all - day shade with bright collateral lighter , which results in rich , sheeny foliage and dependable efflorescence show .
Normal Plant Appearance
Hidden gingers typically reach 2 to 3 metrical unit tall , most of that accounted for by the wide bananalike leaves which arise from the plant on long , fleshy stalks . Healthy leave-taking should be light pleated , undimmed green or edged in ashen , depending on the variety . These leaf will somewhat hide the flowers once the casing - pinkish flower appear . Overexposed plants with loop leaf will probably soldier on , but certainly will not look as full or salubrious as those growing in more specter — the leaves may modernise patchy , sunburned spots .
Dormancy
As secret gingerroot approach quiescency for winter , the leaves begin to yellow and curl before turning brown and shrink away . This is normal , and can not be stopped or detain even in a greenhouse . Though they are hardier than other types of gingers , if you survive in USDA zone 8 , it ’s skillful to lift hidden ginger rhizomes for storage in a peat - fill throne . If you exist in USDA zone 9 , mulch heavily . In USDA geographical zone 10 , the plants do n’t need extra forethought . Do n’t water during the abeyant full point , as the rootstalk waste easily in overly moist soils .
Curled Leaf Impacts
Curled leaves on a works growing in too much Sunday is generally only a cosmetic issuance and should not in earnest impact the health of the works . The plant may bloom less frequently or produce smaller flowers when grow in too much sun . If your hidden ginger often and systematically have curl parting , dig them up and replant them in a better spot in fall . While it is all right to impart the works where it is , the curled leaves detract from the plant ' appearance .
