Leaves are slightly larger in L. chinense, compared to L. tulipifera, but with considerable overlap between the species; the petiole is 4–18 cm long. Leaves on young trees tend to be more deeply lobed and larger in size than those on mature trees. In autumn, the leaves turn yellow, or brown and yellow.
The reduction of chlorophyll production in leaves due to decreased sunlight in the autumn explains why some leaves turn yellow. However, the yellow color can attract aphids, so some trees turn the leaves red instead by injecting a bright pigment. [8] The loss of chlorophyll may also contribute to the abscission process.

Harpullia pendula is a tree that typically grows to a height of up to 15 m (49 ft) with a dbh 60 cm (24 in), its new growth with soft, fawn-coloured hairs. Its leaves are paripinnate, 100–300 mm (3.9–11.8 in) long with 4 to 8 elliptic to egg-shaped, thin, leathery leaflets with the narrower end towards the base, mostly 55–105 mm (2.2–4.1 in) long and 20–40 mm (0.79–1.57 in) wide on ...

The tepals are normally oval. The filaments are black or blackish purple, the anthers yellow or black. Tulipa armena is placed in the subgenus ...
Tulip stems have few leaves. Larger species tend to have multiple leaves. Plants typically have two to six leaves, some species up to 12. The tulip's leaf is cauline (born on a stem), strap-shaped, with a waxy coating, and the leaves are alternate (alternately arranged on the stem), diminishing in size the further up the stem. These fleshy ...
Tulipa gesneriana, the Didier's tulip [2] or garden tulip, is a species of plant in the lily family, cultivated as an ornamental in many countries because of its large, showy flowers. This tall, late-blooming species has a single blooming flower and linear or broadly lanceolate leaves.
Japanese maple autumn leaves. Autumn leaf color is a phenomenon that affects the normally green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, various shades of yellow, orange, red, purple, and brown. [1]
Parrot tulips are the result of natural mutations to single late tulips and triumph tulips. [6] During the 17th and 18th century the most notable mutations were to color patterns with growers attempting to influence the color of the tulips using pigeon droppings, old plaster and even dirty waste water from the kitchen.
