Despite the common names ringworm and dermatophyte, the disease is caused by a fungus, not a worm or plant. Trichophyton, Microsporum, and Epidermophyton are the most common genera that cause ringworm in humans. These organisms feed on keratin, the major structural component of hair, skin and nails.
Thuja occidentalis 'Nigra'. Naturally broad, pyramidal evergreen shrub displays deep green, scalelike needles arranged in flat sprays. New light green needles emerge in spring, deepening in color as they mature. Deep green color adds contrast to winter landscape.
Chlorophyll is also what gives plants their green color. As summer ends and autumn begins, the days get shorter and shorter. With fewer daylight hours, leaves are not able to make as much chlorophyll as they can during the long daylight hours of spring and summer. As the chlorophyll fades, we are able to see other colors, such as orange and yellow, emerge. Many people mistakenly believe that weather makes leaves change color.
