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.
The lateral leaflets of each stem leaf may be lobed, giving the appearance of five leaflets per leaf. Each leaflet is up to 5 cm (2.0 in) long, with serrate leaf margins (edges) and branched (not parallel) veins. The flower stalk rises directly from the leaf whorl. The solitary flower is 2–2.5 cm (0.8–1.0 in) across with 4–9 (usually 5 ...
The plant grows 3-8 feet tall with an unbranched stem until reaching the inflorescence at the very top. [5] Its yellow flower heads, which bloom in late summer through early fall, are 1-2 inches wide and consist of up to 10 bright yellow ray florets that are angled downward, each bearing a notch at the end, as well as a spherical cluster of ...
Symphyotrichum puniceum (formerly Aster puniceus), is a species of flowering plant in the family Asteraceae native to eastern North America. It is commonly known as purplestem aster, [3] red-stalk aster, [4] red-stemmed aster, [5] red-stem aster, and swamp aster. [6]
Teasels are easily identified with their prickly stem and leaves, and the inflorescence of purple, dark pink or lavender flowers that form a head on the end of the stem(s). The inflorescence is ovoid, 4–10 centimetres (1.6–3.9 in) long and 3–5 centimetres (1.2–2.0 in) broad, with a basal whorl of spiny bracts .
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
The erect, branching stem is purple, smooth, hollow, and sturdy. The compound leaves are bipinnate , with 3 to 5 leaflets per leaf. The total width of a lower leaf may be up to 2 ft (61 cm), and the leaflets are 0.75–4.5 in (1.9–11.4 cm) long and 0.5–2.5 in (1.3–6.4 cm) across.
