The flower is pollinated by bumblebees and other bees. The bulbs are an important and preferred food of the grizzly bear. Mule deer readily eat the foliage. [11] [12] [13]After hummingbirds migrate 1,500 miles each year from Mexico to the Rocky Mountains of Colorado they collect energy from the nectar of the lilies, however, rising temperatures from global warming cause the flowers to bloom ...
The plant is 15–90 cm (6–35 in) tall. The fern-like leaves are lobed and grouped in threes, growing from the base and off the flowering stems. The flowers are 1–2 in (2.5–5.1 cm) long and have yellow petals with a red spur and red sepals. They appear in late spring (usually in May and June), nodding on stems above the leaves.
A yellow trout lily produces an erect flower stalk with a nodding, bisexual flower with 6 recurved, yellow, lanceolate tepals. The 20 to 33 mm long tepals are composed of 3 petals and 3 petal-like sepals. [3] E. americanum does not flower for the first 4 to 7 years of its life. [5] [6] In any given colony, only 0.5% will have flowers. [8] [3]
Yellow loosestrife is a tall downy semi-evergreen perennial plant with an upright habit, 50–150 centimetres (20–59 in) high, with erect panicles of conspicuous yellow flowers. [ 5 ] : 519 The edges of the petals lack the fringe of hairs seen in L. punctata , and the hairy, narrow triangular sepals have a conspicuous orange margin.
The second-year plants normally produce a single unbranched stem, usually 1–2 m tall. In the eastern part of its range in China, it is, however, only reported to grow up to 1.5 m tall. [ 5 ] The tall, pole-like stems end in a dense spike of flowers [ 3 ] that can occupy up to half the stem length.
Solidago altissima, the tall goldenrod [5] or late goldenrod, [6] is a North American species of goldenrod in the family Asteraceae which is widespread across much of Canada, the United States, and northern Mexico. It is common in much of its range and fairly tolerant of landscapes which have been disturbed by humans.
The showy yellow flowers, about 1 inch (25 mm) across, grow 2 to 4 together in clusters on the stem. Flowers normally bloom July-September. The fruit is a straight, narrow pod 1.5 to 2.5 inches (38 to 64 mm) long, which splits along 2 sutures as it dries; the pod sides spiral to expel the seeds some distance from the parent plant.
