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]
Each palmate leaf is made up of 6 to 8 leaflets about a centimeter long and a few millimeters in width. The inflorescence is a petite spiral of flowers a few centimeters long just arising past the basal disc of leaves. Each flower is 6 to 8 millimeters long and bright blue in color, generally with a white or yellowish spot on its banner.
It has green to gray-green palmate leaves, with 5–12 leaflets per leaf. The leaflets are 2–6 centimetres (0.79–2.36 in) long, often sparsely covered with fine silky hairs. In spring it bears many racemes, 30 cm (12 in) long, of fragrant, soft yellow, pea-like flowers. [1] [2] Both yellow and lilac to purple flowering forms are known ...
The spot on its banner is white to yellow turning red once the flower is no longer fertile. This color change makes the flower less visible to bees so they continue on to more fertile flowers. The palmate leaves are each made up of about seven leaflets. In the wild, white and even pink blooming plants are very rarely observed.
Lupinus excubitus is a small shrub with gray-green foliage. The fan-shaped leaves are borne on the stem and may be clustered at the base. Generally covered with silvery hairs, each is made up of 7 to 10 narrow 5–50 millimetres (0.2–2.0 in) leaflets. The raceme inflorescence is a tall stalk of rich purple flowers, each with a bright yellow spot.
While these plants are relatively low maintenance, it’s not unusual for peace lily leaves to turn yellow here and there due to stress, pests, or other issues. This guide explains the most common ...
The leaves are palmately compound with 9–17 leaflets 3–15 centimetres (1.2–5.9 in) long. The flowers are produced on a tall spike, each flower 1–1.5 centimetres (0.39–0.59 in) long, most commonly blue to purple in wild plants. The flowers are mostly visited by bumblebees. [5]
It has some leaves shorter leaf stalks growing from the flowing stem. [3] Lupinus prunophilus flower photographed in White Pine County, Nevada. The flowering part of each stalk (the raceme) will have 25–68 flowers and be 6–28 centimeters long.
