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 basal leaves are much more numerous with the 7–30 centimeter long leaf stems [3] spreading in every direction to from a rounded tuft of leaves. [2] Each leaf is made up of 8–13 small leaflets, [ 3 ] each leaflet is 4–8 centimeters long and rarely less than 10 millimeters wide. [ 4 ]
An array of leaves encircles the base. 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 ...
Lupinus lepidus is a small hairy perennial that reaches 10 to 61 centimetres (4 to 24 inches). [3] Palmately compound leaves extend up the stem, but most are basal . [ 3 ] The inflorescence is a dense spike-like raceme , with pink, purple, or blue flowers that often have a yellowish spot. [ 3 ]
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.
The amount of fertility and moisture generally dictates the height of the plant. Prefers moist clay or heavy soils in full sun. Each palmate leaf is made up of 7 to 9 leaflets up to 6 centimeters long. The inflorescence is a series of whorls of flowers each between 1 and 2 centimeters long. The flower is generally purple-blue with a white or ...
Lupinus polyphyllus, the large-leaved lupine, big-leaved lupine, many-leaved lupine, [2] blue-pod lupine, [3] or, primarily in cultivation, garden lupin, is a species of lupine (lupin) native to western North America from southern Alaska and British Columbia [4] and western Wyoming, and south to Utah and California.
It is a perennial herbaceous plant growing to 40 to 80 cm tall. The leaves are palmately compound, with 7 to 13 leaflets each 2 to 5 cm long. The flowers are produced in whorls on a spike 12 to 20 cm long.
