Found on an exposed headland in nature, it grows as a low mat-like perennial shrub 8 cm (3 in) high and 60 cm (2.0 ft) across. The foliage is green and rough and the flowers are 3 cm in diameter and yellow in colour with an orange disc. [52] It makes an ideal plant for rockeries, and strikes easily from cuttings during the spring growing period.
Melilotus officinalis can be an annual or biennial plant, and is 120–180 centimetres (4–6 ft) high at maturity. [3] Leaves alternate on the stem and possess three leaflets. Yellow flowers bloom in spring and summer and produce fruit in pods typically containing one seed. Seeds can be viable for up to 30 years.
The large, showy, golden yellow, trumpet-shaped flowers are in clusters at the ends of branches. The corolla of the flower is bell- to funnel-shaped, five-lobed (weakly two-lipped), often reddish-veined in the throat and is 3.5 to 8.5 cm long. Flowering takes place from spring to fall, but more profusely from spring to summer.
The flowers are bright yellow, 7–10 cm (2.8–3.9 in) across, with the typical iris form. The fruit is a dry capsule 4–7 cm (1.6–2.8 in) long, containing numerous pale brown seeds. I. pseudacorus grows best in very wet conditions, and is common in wetlands, where it tolerates submersion, low pH , and anoxic soils.
The petals of each flower are fused together to form a trumpet shape, 2–4 cm (0.8–1.6 in) across at the mouth, which has five to eight lobes. Inside the flower there are five to eight stamens . After fertilization , a globular white fruit (a drupe ) forms, 8–12 millimetres (0.3–0.5 in) across, containing from one to four seeds.
Black medick has small (2–3 mm) [9] yellow flowers grouped in tight bunches (compact racemes). On larger plants the flower heads may reach 8 mm ( 5 ⁄ 16 in) or more. [ 3 ] The fruit is a single-seeded pod, 1.5 to 3 mm in diameter, [ 9 ] that does not open upon maturation, but hardens and turns black when ripe.
