Characteristics vary among leaves on the same plant. They occur on the base, stems, and branches and become smaller the farther away from the base they grow. By the time flowers appear, the leaves at the base and on the stem have often withered or fallen. [3] The leaves are thin, have short hairs on the edges (margins), and come to a point.
The base of the leaf stalks (petioles) is greatly expanded. Smyrnium olusatrum, common name alexanders (or alisander) is an edible flowering plant of the family Apiaceae (Umbelliferae), which grows on waste ground and in hedges around the Mediterranean and Atlantic coastal regions of Europe.
Silene flos-cuculi forms a rosette of low growing foliage with numerous stems 20 to 90 centimetres (8 to 35 + 1 ⁄ 2 inches) tall. The stems rise above the foliage and branch near the top of the stem. The leaves are paired, with the lower leaves spoon-shaped and stalked. The middle and upper leaves are linear-lanceolate with pointed apexes.
A combination of characteristics is usually required to identify the plant. Identification of a non-flowering, non-fruiting plant with bare leaves may be difficult. Although some species of Trillium have petioles (leaf stalks) and/or distinctive leaf shapes, these features are seldom sufficient to identify the plant down to the species level.
Symphyotrichum lateriflorum is a clump-forming perennial that grows 20–120 centimeters (3 ⁄ 4 –4 feet) tall and up to 30 cm (1 ft) wide. [4] Herbaceous and with alternate leaves, [5] it can have a different appearance throughout its lifespan or a season.
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.
Panicled aster grows from a rhizome and has a thick, erect stem that can reach 1.5 meters (5 feet) tall or more, sometimes approaching 2 m (6 + 1 ⁄ 2 ft). The leaves are generally hairless but may feel slightly rough to the touch on the top because of tiny bristles. The leaf blades have winged petioles and may sheath the stem at their bases ...
This bulb flower naturalizes well in gardens. The bulb grows best in well-drained soil high in humus. It will grow in lightly shaded forest areas and on rocky outcrops as well as in open meadows or prairies. Additionally it is found growing alongside streams and rivers. The plants may be divided in autumn after the leaves have withered. Bulbs ...
