Leaf flushing or leaf out is the production of a flush of new leaves typically produced simultaneously on all branches of a bare plant or tree. Young leaves often have less chlorophyll and the leaf flush may be white or red, the latter due to presence of pigments, particularly anthocyanins . [ 1 ]
Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
This can happen when an air layer is located just under the epidermis resulting in a white or silvery reflection. [8] It is sometimes called blister variegation. [citation needed] Pilea cadierei (aluminum plant) shows this effect. Leaves of most Cyclamen species show such patterned variegation, varying between plants, but consistent within each ...
Mesquite is a common name for some plants in the genus Prosopis and Neltuma, both of which contain over 40 species of small leguminous trees. They are native to dry areas in the Americas . They have extremely long roots to seek water from very far under ground.
The trees were still bare, but wildflowers peeked through the leaf litter. Mortenson Winlock named the ones we saw along the way — Mayapples, Dutchman’s breeches and trout lilies. “Sorry ...
Some experimentation on plant litter from marcescent trees indicates that keeping the leaves above ground may increase the amount of photodegradation the leaves are exposed to. Because some marcescent species' leaves do not decompose well, the increased photodegradation may allow them to decompose better once they finally fall off the tree.
There is a myth that Judas Iscariot hanged himself from a tree of this species, causing its white flowers to turn red. [10] This belief is related to the common name "Judas tree", which is possibly a corrupted derivation from the French common name, Arbre de Judée , meaning tree of Judea , referring to the hilly regions of that country where ...
