Flamboyant with Hyères, SESBANIA Punicea |

SABANIA PUNICEA (Flamboyant by Hyeres,  or  SESBAN Scarlet) is a decorative shrub of 2 to 3m which produces flowers of red-orange color , with deciduous leaves. It is a plant that needs a lot of water, it develops in marshes or humid places. It also prefers a slightly acidic soil, of a pH between 6.1 and 6.52,3.

5 seeds - Average germination: 70%

This species is native to Brazil, Argentina, Paraguay and Uruguay. He has spread to parts of Africa, other parts of South America, and many coastal expanses in the southern United States. Due to its strong need in water, this species adopts  most often of the swampy banks. It can also form dense and prosperous thickets in disturbed areas4.

This shrub has deciduous leaves which are alternate and composed with between 5 and 20 pairs of elliptical leaflets. The edges of the leaves are generally whole, with little or no lace. Each leaflet is oblong in shape and ends with a pointed end. The leaves contain generally discreet stipules. These plants produce both fruits and flowers at the end of the stems. The branches of this shrub are rather thin, and are originally green, but saw dark red brown when they arrive at maturity. The bark varies from a gray to a red brown with obvious horizontal lens8,9.

Flowers resemble pea flowers, 2–3 cm long, and are often red-orange or red-pourpre. These flowers are often found in a racemically. Characteristic of the Fabaceae family, this species has five welded sepales and five free petals. The flower still contains 10 stamens, sometimes with various combinations of merged nets. The ovary is superior and the style is often bent. Characteristic of the Faboideae sub-family, these flowers are zygomorphic and have a specialized structure. The upper petal is called the banner, and encapsulates the petals when they are in the bud. The two adjacent petals, called the wings, the overlap of the lower part of two petals. The bottom of the petals are often merged with apex, forming a structure called the keel. Flowers often appear bizarre and " sighted " because they are most often pollinated by insects, the use of these tactics is simply a call to pollinators.
The fruits are large pods, like peas, compartmentalized in four and appear as if they had slightly shrunk due to drying. These fruits are dehiscent and dry as they ripen. Each fruit can contain between five and ten seeds, which are only dispersed when the pod and opens. The number of pods found on a single plant depends on the age and growth conditions of the plant. On average, a single plant can produce 100 to 300 pods. When the pods emerge on the plants and are not yet completely mature, they are yellow or green in color. As the season progresses, these pods become darker green, possibly becoming dark brown. These seeds often remain on the plant during the winter, and the seeds inside create a distinct rattling noise when shaken by the wind, which gives the plant its common name of "rattle"10,11
