Trifolium campestre, commonly known as hop trefoil, [1] field clover [2] and low hop clover, is a species of flowering plant native to Europe and western Asia, growing in dry, sandy grassland habitats, fields, woodland margins, roadsides, wastelands and cultivated land. The species name campestre means "of the fields".
Flowers appear April to May at the end of each stem in a group, or umbel, of 2 to 6, occasionally only 1. The flowers are 5–13 mm (0.2–0.5 in) long, with 3 yellow petals and 3 yellow sepals spreading outwards. The flowers will open in the morning but typically wilt in the hot afternoon sun.
The yellow star-thistle plant has the ability to create monotypic stands and habitats in the cultivated soil of fields, graded dirt sites, and disturbed natural ecosystem lands. Its colonization eliminates and prevents other plant species from growing, terminating the habitat's biodiversity. Extensive spreading monotypic fields of yellow star ...
Turnera ulmifolia grows erect, with dark toothed leaves and small, yellow-orange flowers, and is often found as a weed growing on roadsides. These yellow flowers bloom around 6:00 a.m. and wilt around 11:30 a.m. Life span for flower is around six hours. These plants can survive on minimum water and grow on walls, cement blocks, and rocks.
Geum aleppicum, commonly called yellow avens or common avens [1] is a flowering plant native to most of the temperate Northern Hemisphere, from eastern Europe across Asia and North America. It is a herbaceous perennial plant growing to 1 m tall with pinnate leaves. The flowers are 2 cm diameter, yellow, with five to seven toothed petals. [1]
This is a hairy annual or biennial herb producing stems which grow upright or lie along the ground to a maximum length of 30 to 40 centimeters. [5] It produces yellow flowers May–July that fade to white with four small petals about 1.5–3 mm long. [6] [7] The fruit is a round, hairy capsule up to half a centimeter long.
Mature plants range in height from 0.8 to 1.5 m (2.6 to 4.9 ft). [5] Flowering begins in late spring and may continue into the summer. The specific name means "yellow" in Latin and refers to the flowers, which may be white to pale yellow. The flowers measure 18–28 cm (7.1–11.0 in) in diameter and have 22-25 petals. [5]
It flowers very profusely, [50] and the large flower heads are borne on stalks 5–9 cm (2–3.5 in) above the foliage. Unlike other forms, the stems wither and die naturally after flowering, making way for more new growth and flowers. [51] The flower heads are golden yellow and measure 6 cm (2.5 in) across. [7]
