The leaves of the other shore flower
Along the wild path during the autumnal equinox, you can always see the figure of the other shore flowers blooming like flames. The most fascinating thing about this plant, known as the "Hell's Flower", is the fact that its flowers and leaves never see each other. When we stare at its slender leaves, have we ever wondered what kind of survival wisdom these green leaves contain? Careful observation of the garlic leaf shape with unique morphological characteristics of the leaves of the trees are arranged in a bulbous shape, and the 30-cm slender leaf body is only 0.5 cm wide. This shape resembling garlic sprouts is actually a typical feature of Amaryllidaceae plants. The white waxy layer covered on the surface of the leaves will condense crystal dew in the morning. The color code of the leaves Most varieties show emerald turquoise, and the midveins of some rare varieties show milky white stripes. As the seasons change, the leaves will undergo a color evolution from tender green to dark green and finally yellowing. This color change mechanism is closely related to changes in carotenoid content in the leaves. Analysis of the life code growth cycle of alternating leaves and leaves. After the flowering period ends in September every year, underground bulbs begin to germinate new leaves. These leaves continue to photosynthesize during the winter, storing nutrients for the next year's flowering. Before the plum rainy season in June of the next year, the leaves will complete their mission and naturally wither, making room for the growth of the scapes. Environmental adaptation intelligence, the habit of alternating flowers and leaves, is actually an evolutionary result of coping with the East Asian monsoon climate. Dormancy avoids high temperatures and rains in summer, blossoms in autumn attract pollinators, and long leaves in winter use the mild climate for photosynthesis, perfectly adapting to seasonal changes. Leaf maintenance points Yellow leaf warning signal The leaves of the lily
Unnaturally wilting yellow leaves often imply environmental abnormalities. When the leaves are found to turn yellow in advance, it is necessary to check whether water is causing bulb rot, or direct light is causing chlorophyll to decompose. Maintaining the ambient temperature of 18-25 ° C and scattering light lighting can keep the leaves healthy. Horticultural planting techniques It is recommended to use a mixed substrate of humus soil and river sand, and regularly supplement phosphorus and potassium fertilizers. Pay attention to drainage in the rainy season, and volcanic rock particles can be laid on the ground. When wintering in northern regions, it is recommended to cover a 5 cm thick insulation layer of pine needles. Leaf cultural image In Japanese classical literature, the green leaves of the other shore flower are called the "leaves of missing", symbolizing the attachment of the living to the dead. These slender leaves often appear in the background of Ukiyo-e, forming a strong contrast with the bright red flowers, implying the philosophical thinking of life and death.
