Foliage of an 'albino' redwood. An albino [a] redwood is a redwood tree which is unable to produce chlorophyll, and has white needles instead of the normal green. It survives by obtaining sugar through the connections between its roots and those of neighboring normal redwood(s), usually the parent tree from whose base it has sprouted.
The most infected needles are prematurely shed by December. Because the infected needles are within the interior of the tree, the newer needles on the outer surface of the pines are flushed green and resistant to the disease. However, the premature shedding of needles in the interior can extend outwards leading to a loss in overall growth.
Thanks to glossy green leaves and big bright red blooms, bromeliads make for an ideal holiday decoration―even more so because they don't require consistent sunlight and won't shed! So, you don't ...
These are evergreen perennials with stems growing erect or decumbent and creeping. Stems that grow along the ground may root at the nodes. Stems that grow along the ground may root at the nodes. There is generally a crown of wide leaf blades which in wild species are often variegated with silver and green coloration.
Usually trunkless, it is multisuckering with heads of 75 centimetres (30 inches) long, filamentous, blue-green, strappy leaves. Y. filamentosa is readily distinguished from other yucca species by white, thready filaments along the leaf margins. [4] Flower stems up to 3 metres (10 feet) tall bear masses of pendulous cream flowers in early summer ...
This tree has a mixture of PVC and polyethylene (PE) needles, the latter of which have a molded design that closely resembles real spruce needles. It was the most realistic tree that we tested ...
The leaves (needles) are five per bundle , spreading, 8–14 cm long, 0.6-1.0 mm in diameter, straight, slightly twisted, pliant, dark green to blue-green, and persist 3–5 years. The upper surfaces (adaxial, facing the centre of the fascicle) is conspicuously whitened by narrow stomatal lines.
