Forsythia are deciduous shrubs typically growing to a height of 1–3 m (3 ft 3 in – 9 ft 10 in) and, rarely, up to 6 m (20 ft) with rough grey-brown bark. The leaves are borne oppositely and are usually simple, though sometimes trifoliate with a basal pair of small leaflets; they range between 2 and 10 cm (0.79 and 3.94 in) in length and, rarely, up to 15 cm (5.9 in), with a margin that is ...
Forsythia suspensa is a deciduous shrub that grows up to 3 metres (9.8 feet) tall. Its flowers are golden-yellow and they bloom March to April. [2] Leaves are green in color, broadly-ovate, and simple. [2] It can be grown as a weeping shrub on stream banks and can be identified by its pale flowers. Garden cultivars can be found. It is a spring ...
Leaf spots can vary in size, shape, and color depending on the age and type of the cause or pathogen. Plants, shrubs and trees are weakened by the spots on the leaves as they reduce available foliar space for photosynthesis. Other forms of leaf spot diseases include leaf rust, downy mildew and blights. [4]
The opposite leaves turn yellowish or occasionally purplish in the autumn before falling. [3] The bright yellow flowers are produced on one- to two-year-old growth and may be solitary or in racemes from 2 to 6. [2]

The presence of hairs on leaves, which may be coloured differently from the leaf itself, can also produce variable coloration. This is found in various Begonia species and their hybrids. Sometimes venal variegation occurs – the veins of the leaf are picked out in white or yellow. This is due to lack of green tissue above the veins.
