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 broadly ovate, pink or white petals of an Anacampseros telephiastrum flower The loosely-arranged, brown-green, papillate leaves of An. telephiastrum. A small branching species with loosely-held 18mm long leaves. The leaves are brown-green with papillae and tiny points (mucros) at their tips.
Leaves retain their yellow border from the initial chlorosis. Apothecia survive in the fallen plant debris over winter, releasing spores when the temperature is warm again. [ 5 ] The infection of Tar Spot is localized to the chlorotic areas on the leaves and is mostly a cosmetic issue, rather than an economically detrimental disease.
The fairy duster flowers are a pale pink color and are an attraction to animals that live in the desert. This plant becomes a source of food for the deer that roam in the desert or hillsides. The plant also attracts butterflies, bees and hummingbirds for nectar when the flowers are blooming.
Prolonged exposure to overspray of glyphosate will cause yellow leaves and new leaves will be small and elongated. Hormone weed sprays (e.g. 2,4-D and 2,4,5-T) may cause grotesque new growth with thin twisted leaves and distorted buds. Plants may die in severe cases.
The leaves are opposite, oval and pointed. They are borne by petioles of 2 to 4 cm 1. The most common type has green leaves with pink spots, although it can range from white to any shade of pink to red. The spots on the undersides of the leaves are far lighter in color, often white. It may produce small, solitary pink/purple flowers at the ...
Growing to about 13 cm (5 in) high at most and covering a 50 cm (20 in) wide area, it is an evergreen perennial forming mats or cushions of hairy, linear leaves. The small, five-petaled flowers bloom in rose, mauve, blue, white, or pink in late spring to early summer. [3] Its habitats include rocky ledges, slopes and clearings. [4]
Producing pink or white flowers from spring to autumn, it forms underground tubers and large rootstocks. It is a prolific seed producer. The seeds float on water. The fruit and seeds are eaten and spread by a wide range of animals such as pigs, racoons and birds. The tubers will resprout if the plant is cut back or damaged by frost.
