As the pod matures on the plants, it dries and splits open in the sun. The seeds will eventually fall out of the hard, dry, pod to the earth - or gardeners can remove them for storage or planting later. Bean seeds are actually comprised of two halves called cotyledons. Each cotyledon contains a food source for the emerging plant.
Castor bean is an exotic addition to the garden.
The first leaves to emerge from a bean plant do not look like the typical bean plant leaves. They're rounded, and help the plant grow quickly into a strong, mature plant. These leaves (also termed cotyledons) emerge above the ground, as opposed to below the soil surface which is common in other plants, and are connected to the seed. Ricinus communis, the castor bean or castor oil plant, is a species of perennial flowering plant in the spurge family, leslutinsduphoenix.com is the sole species in the monotypic genus, Ricinus, and subtribe, leslutinsduphoenix.com evolution of castor and its relation to other species are currently being studied using modern genetic tools. It reproduces with a mixed pollination system which favors selfing by.

With oversized, tropical-looking leaves and bizarre seed pods, castor bean is an exotic addition to the ornamental garden. The only member of the genus, Ricinus communis is in the Spurge Family Euphorbiaceae. Castor bean is native to tropical east Africa around Ethiopia, but has naturalized in tropical and subtropical areas around the world to become a weed in many places, including the southwestern U.
Plants are typically Bean plant growth in moist, well-drained soils in disturbed areas, such as along river beds and roadsides, and in fallow fields or at the edges of cultivated lands. Bean plant growth bean is a fast-growing tender perennial large shrub or small tree.
Castor bean is an evergreen herbaceous or semi-woody large shrub or small tree. This robust tender perennial can grow to 40 feet tall, developing woody stems over a few years in frost-free climates.
Because of its rapid, vigorous growth, it is easily grown as a warm season annual in temperate climates, but it rarely exceeds feet in a single growing season.
This fast growing plant tends to grow straight up at first, developing branches later in the season to form a well-proportioned shrub with sturdy stems and a dense canopy.
The plant is killed when the temperature drops below 32F. Unlike many members of the euphorbia family, this plant does not have milky latex sap, but has a watery sap. The large palmate leaves have many deeply incised lobes. Each palmate leaf has 5 to11 deeply incised lobes, with serrated edges and prominent central veins.
The species has glossy green leaves, but cultivated selections may have black-purplish, dark red-metallic, bronze-green, or maroon leaves, or bright green leaves with white veins. The monoecious plants produce male flowers below the terminal female flowers. The flowers do not have petals and are not particularly showy.
They senesce soon after shedding their pollen.
The three conspicuous, star-shaped stigma lobes of the female flowers are bright red with feathery branches. The small male flowers are produced below the more conspicuous terminal female flowers.
The little spiny ovary of the female flower develops into a fruit or seed capsule about the size of a golf ball after pollination. The seed pods may be green, pink, or red depending on the varietybut gradually age to brown. Each spherical, seed capsule is thickly covered with soft flexible spines and has three sections that separate when the seeds are mature.
Each section contains one seed that is ejected, often with considerable force, when the carpel splits open. The spiny seed pods may be green Lpink or red Cbut eventually turn brown and split open when ripe R.
The shiny, intricately mottled seeds are quite attractive, each with their own unique design in colors of black, gray, brown, yellow-brown, maroon and white. The intricately mottled seeds have a spongy caruncle at one end.
Each seed has a small, spongy caruncle at one end which helps absorb water for germination when planted. Seeds remain viable for years. About half the weight of the seed is a thick, yellowish or almost colorless oil that has been used in many industrial applications.
The oil was used in ancient times as fuel for lamps, and is now used in paints and varnishes, for water-resistant coatings, in high-performance motor oils, soap, inks, and plastics. Other derivatives are used in polishes, as solid lubricants, in synthetic perfumes and other products.
Plants are grown commercially for oil production primarily in India and Brazil, but also in some parts of the U. The seeds are extremely poisonous, so keep plants out of reach of children or trim off flowering spike if this is a concern.
The toxin in castor seeds is ricin RYE-sinone of the deadliest natural poisons, estimated as 6, times more poisonous than cyanide and 12, times more poisonous than rattlesnake venom. As few as four seeds can kill an average-sized adult, while ingestion of lesser amounts will result in vomiting, severe abdominal pain, diarrhea, and convulsions.
Livestock and poultry can also be affected if they consume seeds or meal from the seeds. Although it is a very potent poison, ricin has been investigated as an anti-cancer agent.
Since the toxin does not occur in the pure oil, castor oil can be consumed and has been used medicinally as a remedy for everything from constipation to heartburn. It is an effective cathartic or purgative laxative and can be used externally as an emollient for dry skin.Deciding what variety of bean you want to grow and whether to grow the bush or pole type plant is important when you are planning your garden.

A bean is a seed of one of several genera of the flowering plant family Fabaceae, which are used for human or animal food. Avoid bean growing problems by growing beans when temperatures have warmed and nights are no longer chilly.
May 15, · How to Grow a Bean Plant. Beans are a great plant for beginning gardeners to grow, as they are very easy to plant, maintain, and harvest.
The stages of bean seed growth are vegetative (V), with a number of stages corresponding to the number of leaves, and reproductive (R), with eight stages culminating in full maturity of the bean pods. The names and nature of stages are specified by The Iowa State University staging system. As a bean. Deciding what variety of bean you want to grow and whether to grow the bush or pole type plant is important when you are planning your garden. Green beans are probably the most widely grown in the vegetable garden. A bean is a seed of one of several genera of the flowering plant family Fabaceae, which are used for human or animal food.
Beans have the added value of being highly nutritious, giving you all the more reason to add them to 68%(69). Research has shown that applying soluble calcium with urea, an ammonium form of nitrogen, can improve crop production.
